Hard work pays @ 5th Lions Vredendal Gymkhana

September 15, 2011 Herman Mathee Leave a comment

The weeks preceding the event was very busy, especially in the home of the two Mathee brothers, we basically spend all our time between work, the garage, bed and Selina made sure we had enough coffee to keep us going. Mike played with a combination of different gearboxes, cams, etc. in the Fox. He either had way too much time on his hands or was determined to make the Fox a more competitive vehicle, I ran out of fingers counting the past 12 evenings he spend underneath that car.

After the Piketberg event, Mike and I decided that “Lil Datto” either needs a lot more rpm or a different differential ratio, as 1st gear was way too short for the straights and 2nd to dead. Between building my new race car “Datto LINK” I managed to source a very special ratio BMW E36 open differential. Luckily for me all the talk on the forums was correct when they stated that the E30 and E36 Medium case differentials use the same internals, this made building a custom ratio E30 Limited slip differential quite easy, poor “Datto” had to sacrifice his differential for the custom unit. Ruan and I spend time under the rear suspension of “Lil Datto” to get this new unit installed, the results was better than we expected, there is a big difference between theory and principle. “Lil Datto” was

so abused at the Piketberg gymkhana that we just had to double check every single suspension bolt, gave it a good rub with polishing cream and polish, at least the little car now looks as if it is only one colour.

A big thanks must go out to Johan Spies from Bergsig Motors 023 3412826 @ Worcester who extended an invitation to Pietie, Mike and myself to transport our vehicles to Vredendal and back, this meant we could drive thru to Vredendal without the worries of towing a vehicle and could have a nice and relaxing drive to Vredendal, the only drawback to this was the fact that everything had to be ready Wednesday evening as we had to take the Fox and Datsun to Worcester Thursday evening were they were loaded the Friday morning for their journey to Vredendal.

Saturday morning started with the usual, 6am wake up, get everything ready for the day. On arrival at the venue we were greeted with quite a surprising fog cover, something one of the locals told us is very uncommon this time of the year, well this was not going to stop us from getting everything ready for the fun to follow later in the day. Selina and Natasha was in charged off the gazebos while the boys kept themselves busy with preparing the vehicles. The usual documentation was finished and the weapon was put to good use learning the track. The use of the bicycle really aids in getting the route faster in your head.

Herman Mathee and Mike Mathee in Class F Datsun 1200 – 2nd in Class F and 9th Overall

Being on an Airfield, we were allowed to warm our tyres and drive train before a run, an opportunity I grasped with open arms as this would’ve been the first opportunity to get a feeling for the new differential with tight turns and hard acceleration. On the start line, looking at the first corner, it really looked very far and I knew we will be sitting on the limiter to the breaking point, we launched, what a surprise, it was must faster and the acceleration was much better than with the previous differential, but this was short leaved as we hit the limiter, which felt like just after the start, we went thru the 1st figure of 8 and on the entry changed to 2nd, this felt very nice as ‘Lil’ really accelerated hard to the next figure of 8, back to 1st and on the entry shifted to 2nd. Drifted the car into the slalom, once at the bottom, Mike quickly realised that I was

way too busy keeping the car on the racing line, he quickly changed the car back to 1st, all I had to do was time the clutch pedal. Entering the slalom, changed to 2nd, thru it and then a hard acceleration thru the last kink to the finish. This being Vredendal and the one course that I really like to test a cars handling and my own abilities, I had a nerves lift going thru the kink. At that point I forgot about the competition and set my own goals for the day as trying to flat foot “Lil” thru the kink.

We ended the round with a 1:04.95. With the goal set, the 2nd round was all about flat footing “Lil” thru the kink, moving thru the route went as previous, only with me trying to change back to 1st coming out of the slalom, which was to slow, on our way back to the finish i almost got the feeling Mike was getting ready for the fact that his little brother is really going to tackle the kink and flat foot it, well he was quite right, I had my mind set at flying thru the kink on the limiter at 78km/h, and that was exactly what we did. Goal achieved for the weekend. Round 3 was almost exactly the same thing, how fast can we enter the kink and sit on the limiter to the end. We flow thru that thing, surprising more than one person with the superb handling and braking capabilities of “Lil Datto”. Only then I realised that the day was at an end, I must admit, Kobus Wilson was untouchable on this specific route, if only I started concentrating at driving the complete route and not only the kink, maybe just maybe I could have tried chasing him. The day ended with a 2nd in class position and 9th overall.

I even managed to get “Lil Datto” as the photo on an article on Motorsport South Africa’s website, follow the link to the article: http://www.motorsport.co.za/News/DisplayNewsItem.aspx?niid=11105

Bjorn achieves a personal goal @ 3rd Piketberg Gymkhana

August 18, 2011 Herman Mathee Leave a comment

The weeks preceding the event went by like all the other, check and prepare the vehicles, except Mike fitting power steering to his VW Fox. Everything went smoothly with the installation with one or two issues presenting themselves, understandable if you consider the MK1 Golf/Fox shell was never intended to utilize power steering. Saturday morning 6 o’clock arrived and we started our little journey to Piketberg, on our way to the little town we noticed outside temperatures of 3.5degrees, luckily we packed enough warm clothes to battle the temperatures.

On arrival at the Piketberg Municipal Testing Grounds, we found ourselves a very nice location next to the start/finish on the Piketberg hospital grounds which served as the pits for the day, this allowed us to have out Gazebo’s next to the vehicles which helps allot especially with the vehicles being used multiple times on a specific round with different drivers and navigators. We went about the usual, setup the gazebo’s unpack the gears etc., then moved onto the vehicles. A frames were removed, racing tyres installed and all necessary suspension changes made to accommodate the short bumpy route, seeing that it was so cold outside; tyre temperatures was very high on the list of preparation work. Being the first time that the Race-Tech crew were participating at the event, everything was new to us.

Pietie unfortunately had to cancel his entry with the Mazda F due to improvements currently being done on the vehicle, due to this he could focus on his FWD entry with Mike next to him.

Bjorn Venter and Jan van der Vyver in Class D VW Fox 1.4i – 1st in Class D and 1st Overall

Jan at last convinced Bjorn to start competing again and what a result he achieved with on his return, Bjorn drove magnificently throughout the day, the two of us even disputed his first time and was under the impression he received an incorrect time and waited for round 2, if he could match the time we knew the 1st one was valid. He finished his second round 2 seconds faster than the first round and to make matters worse for the quicker classes was that his time was one of the best for the day in a 1400 powered vehicle which left the rest shell shocked. To sum it up Bjorn slightly bettered his 2nd round time with round 3 and took overall victory on the day, 2seconds faster than the overall championship leader Izak van Zyl piloting the Dynotech turbocharged VW Golf. Quite frankly a shocking surprise but well deserved.

Herman Mathee and Mike Mathee in Class F Datsun 1200 – 1st in Class F and 6th Overall

Having been a quit day for me on the navigating side with only 3 vehicles, which was 6 positions from each other provided me the opportunity to watch some gymkhana for the first time in the last 2 seasons. After making some improvements on the Datsun’s camber/castor plates setup time was reduced considerably. Luckily for me Mike went out on the route before me and could provide with some vital information regarding the track conditions and a few heads-up. We launched nicely, as we moved thru the middle section of the course it became apparent that today is the day that the “Lil Datto” is going to spend a lot of time at 7500 rpm. The first run I used to get familiar with the route and track conditions. On our way from one corner to the next we were sitting on the limiter in 1st, just tapping of at corner entry and then the same all over again. We finished the route with a time of 1:15.26, which we were actually happy with as we knew their isn’t a lot more in the car. This time placed us in 4th in class after round 1. As I did my duties as a navigator the track became warmer and warmer, which could definitely been seen by the other competitors times.
We entered round 2 with the impression that if we could match or slightly better the time we would be happy as we just didn’t have the legs with the car and changing to 2nd could become a problem. We drove thru the route with the car more on the limits, actually started to feel quite sad for the poor thing, but being a A series Datsun motor that thought quickly disappeared. We finished the route with a very impressive improvement and ended posting a time of 1:11.26, which we found quite astonishing. This time promoted us to 1st in class provisionally.
Standing in the line waiting to get to the start was probably the most nerve wrecking to date, as I was currently leading class F with Mike’s car and it would be a first for the car if I could win the class. This particular car is really surprising us race after race, as it is basically just a bunch of slapped together parts that is actually working quite well together. As we pulled away my brain was just telling my arms and legs to do exactly what they did in round 3, but my thoughts was causing the chaos, constantly reminding me that I need to perform if I want to win the class as there was another round after this one. We had the car on its limits throughout the route, but only managed to post a time of 1:12.75, not as great as the previous one, this kept us in 1st place and .7 seconds in front of second place.
We were ecstatic with the day, but we still had one round to complete as

generic viagra online the Clark of the Course was evaluating the possibility of a 4th round if the sunlight would prevail. It was a long nerve wrecking wait, with the only thing to do was to listen to the other class F competitors posting some pretty decent times. Just before the end of the 3rd round the call came out that there will be no 4th round do the sunlight fading very fast. Mike and I won the class and the best thing I could think off at the time was to crack open a Non Alchaholic beer (still had to drive home) to celebrate as we started prepping the vehicles for the open road home.

Selina Botes and Herman Mathee in Class D VW Fox 1.4i – 8th in Class D and 42nd Overall

Race after race Selina is getting more and more to grips with the entire concept of gymkhana, this is her first year competing after attending races last year with me, where I competed, she indicated that she also wants to drive at the end of last year, well what were we to say, we strapped her to the seat of Mike’s Fox one evening at Killarney racetrack and she were threw into the deep end. As time went on she started to realise that there is way more to the sport than just driving, here you have about 2 hours on average to learn the route as there is most definitely no time looking at a map while flying thru the course. With 2 very difficult routes after the opening event it sure was not easy. Although Selina is competing in the big boys class seeing that I’m navigating and encouraging her, if we compare her times with the al ladies class, she would have ended

4th in the class, a brilliant achievement none the less, only time will tell how comfortable she will become behind the wheel. A big thanks goes out to my brother who spend countless hours installing power steering into his VW Fox, which is making the live behind the steering wheel much easier for Selina.

Slippery on Tarmac @ 10th Flamingo’s Langebaan Gymkhana

July 28, 2011 Herman Mathee Leave a comment

Work was frantic on the VW front within the camp. Power steering on the Golf and Fox was the only topic discussed, luckily for me Ruan returned back from his absent due to work commitments in Zambia, at least now I have someone to talk about building our two big project cars, but later more about that. Mike and Jan toyed with the idea of power steering on a VW Golf MK1 shell for a long time and finally decided that they had enough of trying to turn 7″ and 8″ slicks in anger, the time has come for power steering, Jan volunteered to take his motor and gearbox out to help the design process for the modifications, after allot of measurements they could start. Mike spend endless hours in front of the computer designing all the mounting brackets and hardware for the kit to work, after the positive feedback Jan provided after the 5th Fairbridge Mall Brackenfell Gymkhana where he used his newly installed power steering for the first time, Mike started with the Fox, having to make a few changes due to different donor racks, everything looked on track to have the Fox turning with ease at the Piketberg Gymkhana.

Since Ruan’s returned the two of us tried at every possible occasion to catch up on all the car and life related discussions that we missed out on the last two years. Seeing as his car is the one that started this whole idea of racing was standing on blocks half way stripped, there was no possibility for him to use it to compete, Mike was generous enough to allow him to use “Lil Datto” to have some fun with us. Having a set of extra rims and slicks he no longer was going to use on the new and improved Escort, he had there PCD changed for use on “Lil Datto”, this however meant the two off us had some work to do to use these wheels on the “Lil”. The amount I extended the track on the car makes it difficult to use wheels with almost no offset. At the end of the day we had to cut a little more out of the front part of the fenders to get them turning to the maximum at full down travel.

Selina unfortunately injured her back on Friday and was unable to compete, every time I got to the gazebo I could see the pure frustration on her face, sitting and watching everyone else compete was getting the better of her. A few physio sessions later and she will be able to compete at the next event.

My track record at all the events that I participated at Flamingo’s speak for themselves, this isn’t my favourite venue and for some or other reason I just can’t do to good here, maybe it is the surface, slicks not working or just pure driver errors like hurting my arm and then driving over tyres, route errors, I don’t know. This particular route had in everything that I love in a route, fast flowing sections into slow and technical corners etc., a little bit of slow and fast sections is always nice. The route was covered with a new layer of asphalt, something we all looked forward to, as the old asphalt was prone to very high tyre wear. The first few cars onto the route posted some very good times, but from about the 5th car we started seeing the asphalt breaking up and getting the characteristics of a gravel road. As Pietie was only coming thru later on the day I had to navigate for Mike, his starting position is 10 and right from the get go, we noticed that the route had no whatsoever grip. This had me going for a while as “Lil Datto” is quite tail happy exiting a corner when stepping on the gas to much, with the gravel conditions this was either going to be a lot of fun or a huge frustration.

The 1st round went well considering the grip levels, the time was in line with the other fast class F runners, knowing there is huge potential for improvement as the run was very conservative to get a feel for it. Ruan went out with me next to him for his first time this year and also his first time with “Lil”, I must say with a little encouragement from my side he really started driving the car as a RWD should be driven, tight lines with the rear on the border of stepping out. Standing in the line for the start, me and Mike had a discussion around keeping the lines tight to get the times lower. Pulling away and on the route everything went well with Mike keeping me in line very nicely, the rear shifting only marginally from time to time, keeping everything under control and what felt quite fast, then all of a sudden I made a mistake entering a left hander to wide and all hell broke loose when I shifted

to second not realising I was off the clear line starting to form. Once the clutch pedal was completely released and my right foot totally down on the fuel pedal the rear stepped out at which was around 60km/h, Mike shouting all sorts of things at me that sounded quite strange, as he was sitting in the suicide seat it probably looked rather bad from his viewing point as we were approaching a tyre barrier on the right. Luckily I just kept my foot planted in a desperate effort to get the “Lil” under control, once this was done we over shot the braking point by at least 2m, with a combination of a poor man’s ABS braking, Mike on the handbrake we made it, a little wide but safe, the video footage was going to be interesting.

Seeing that the route was cleaning and a racing line was forming on the gravel, times started coming down, as we posted a time 2seconds faster than the first run. We were allowed a fourth run on the day, I was lying in fourth at the end of round 3. We went out not really trying to post a even better time, just wanted to drive the car to its limits as fast as we and the route would allow; and this is exactly what happened, we posted the second fastest time for class F for the day and brought “Lil Datto” home in 2nd position for the day with Ruan marginally behind me in 3rd. I must say he really adopted quit fast to the lesser power levels of “Lil” compared to his Escort. This was the best day of racing this year, hopefully the rest of the events can also compare to this memorable event.

Class D dominance @ 5th Fairbridge Mall Brackenfell Gymkhana

July 21, 2011 Herman Mathee Leave a comment

Weather indicated that this event could turn into a wet one, the possibility presented itself that it could be the same as last year’s event at Neelsie Stellenbosch gymkhana, an event that I really enjoyed since it was something completely new and a different challenge to drive on a drenched track. Friday night we as a team went down to the venue and helped to get all the fences

in place to ease the duties of the organiser for Saturday, this also allowed us the opportunity to have a look at the track and get our heads around it, which really helped at the end of the day. Back at home we packed every last bit of wet weather clothing we could as we were convinced it is going to be a wet one.

Saturday morning we got up and to our disappointment it was looking as if a wet track was out of the question, oh well, can’t get everything in life that you want. We moved down to the Fairbridge Mall and went thru the norm of setting up the Gazebo and prepping the vehicles for some fun before we started the usual walking and learning of the track, again I must add using a bicycle for this purpose is a real benefit.

This was a particular busy day as I had to navigate for 4 other vehicles, two of which is for Kobus Wilson Snr that sure as hell know how to drift a car in very confined spaces, I’ll even put money down that he will put many RSA drifters to shame when the space available is limited. On this particular day Mike and I decided to lend “Lil Datto” to Kobus Wilson Jnr as his bakkie wasn’t available for the particular event, we did this as good sportsman and provide him the opportunity to

gather points for his championship campaign. To date the organizers have decided not to allow him to keep the points that he earn on the day for 2nd place in class f, which left a particular nasty taste in our mouths. Gymkhana being an entry level category into motorsport where participants help each other and try to grow the sport, but the above actions is not the way in which good deeds should be awarded.

Throughout the day I struggled to get the times needed that the other participants was posting for the class, round 1 and 2 was off by about 2-3sec per round from the fastest times for the day, the front suspension felt spongy and i was just unable to drive around this. Kobus was actually able to post times 2sec faster with the Datsun. The last round of the day I was determined to post a time good enough to slot into 3rd place for the day in the class, on the start line my foot slipped on the clutch, for this error under pressure I was awarded with a 10sec penalty which ended my day, at least it provided Mike with the opportunity to really test the handbrake of the Datsun. At the end of the day I’m really disappointed with my results, but luckily I can look back on the day and learn from the mistakes.

The route layout was what we called easy compared to the Vredenburg routes which was a pretty difficult and a nightmare for new competitors. Throughout the day Selina was nervous but full of confidence regarding the route and this started to show with her times. During the day she started to drive harder and harder which will turn into real competitive times as time goes on.

Confusion @ 2nd Weskus Mall Gymkhana

April 11, 2011 Herman Mathee Leave a comment

The week leading up to the event was spent under “Lil Datto” front suspension, having taken it completely apart, to widen the track more. Some interesting male/female extension pieces was machined to allow for further adjustment of the track. The original pieces was on their limits and didn’t allow for more adjustment, the steering arms, was adjusted to use only 10mm of thread, which isn’t considered to be very safe. But from time to time these extreme measure are needed to test a theory in the practical world in order to make the decision if it is worthwhile to spend money on the modification, luckily for me this proved to be a huge success and I went ahead. The end result was a front end which is +- 85mm wider per side.

Another early morning start at 04:00am, packed the cool bags, attached the race vehicles and off we were at 05:15. On arrival at Weskus Mall at 07:00 we immediately started with swapping tyres, adjusting the suspensions and getting everything in place ready for the action to start. Went thru documentation and scrutineering; then the mega task of learning the route started, the itself not that difficult, but the venue with all the little bushes making it very confusing. Once we started with the learning of the route we had absolutely no rest what so ever. Being the most intimidating venue that we have come across in Gymkhana to date, the rest of the season can only be easier. This venue is so bad, I bought myself a video camera, maybe some previewing of the venue would help in the future.

Mike Mathee and Herman Mathee in Class D VW Fox 1.4i – 1st in Class D and 13th Overall

At 10:30 the action started with the first car on the line. Having to

navigate for 6 different entries on the day, the first outing is always the most important, my nerves was shattered and in the back of my mind I was struggling to keep the doubt under control as I was very uncomfortable with the route. Mike was the poor soul that was first on my list, placing the VW Fox on the line, we set off and all of a sudden the doubt cleared and we navigated thru the route with no navigation errors. On his first run he had to select reverse as his incoming line to a hairpin corners was completely off, something that I think was a first for me. Selina found it very difficult to remember the route thru the 30+ identical looking bushes, hopefully being the last time we compete at the venue this year, we can only looking forward to the other venues with their own challenges. The day continued with a straight battle between Mike and Jan for Class D honours, at the end of the day, the battle was decided with a very quick time from Mike on his last run which secured the title for the day. Hopefully on the next event Mike’s regular navigator will be back and for filling his duties next to my brother, as I really do feel additional concern in navigating for my brother and Jan in the same class when they are this competitive.

Herman Mathee and Mike Mathee in Class F Datsun 1200 – 2nd in Class F and 12th Overall

Starting the first round in “Lil Datto” at 5000rpm was a complete nightmare, as the vehicle launched hard and then all of a sudden the revs fell and I had to sit there and wait for it to pick up again; SU’s your days are numbered, going thru the first few corners I could feel something isn’t 100% correct, but once we got to the very technical side of things these concerns was highlighted, the front end felt slow to accept input. We continued thru the route and was the only vehicle in class F to have a clean run thru the route after the first round. Still trying to figure out what was causing the lack of response and front end grip we launched again for the 2nd round, with the revs higher and a little longer on the clutch it was much better. Having decided that we should drive much tighter lines and not overdrive the vehicle we swept thru the corners to stop at the finish line a full 3sec faster than before. Very pleased with this time, we came to the conclusion that the car really does not like to be overdriven and forget about the front end. The 3rd round I was very confident and determined to finish the day with a sub 1min 21sec time, this over confidence soon became apparent as I skipped a part of the course and had to turn around to correct it. Not very pleased with this I set off to have a little fun and practising my handbrake cornering, going thru a ditch and losing 1 bar of air pressure in the one rear wheel was a result of this. After the event when torqueing the wheel nuts on the street wheels, we realised that the front wheels had allot of play on, after inspection it became apparent that the front track rod bushes wasn’t tightened enough, causing the spongy feeling and lack of response.

Never the less, a very fun filled and enjoyable outing and one that will be with me for a very long time seeing that a made a big driving error and need to concentrate on it to rectify it, Lesson of the day: Listen to your navigator, it is there role next to you to keep you on route.

Complete Podium @ 1st Weskus Mall Gymkhana

March 31, 2011 Herman Mathee Leave a comment

During the weeks that passed since the last event all focus was on the preparation of the vehicles with many long nights clocking the hours in, in the garage. Mike decided that this would be the ideal time to fit the 2nd hand 1.4i VW Golf motor to the Fox, this was one of his best ideas to date, but also one of the worst, as this machine had a mind of its own.
To sum it up, after the fires was put out and everything working off it went to DynoTech for some seriously needed mapping on the Gotech side. The map that Jan and Mike developed on the road was quite good and very driveable, until the first power run on the dyno, it was very apparent that the motor had a lot more to offer, they start the process and Izak van Zyl quickly whipped it into shape. Before Izak got his hands on the car it had a sound of a sluggish rotor motor, which I particularly enjoyed, but Izak thought it good to get the motor to its full potential rather than letting it sounds as sweet as it did.

On Thursday evening Mike and Bjorn took the car to our test area to put it thru its passes in order to give the go ahead for competition, and all of a sudden I was called upon to bring the recovery vehicle as there were a strange rattling sound coming from the motor, first thoughts turned to main or big end bearings, but the sound was not familiar. Once back home we hook all the gauges up and started it again, after some time the sounds was diagnosed to be coming from between the gearbox and motor. Jan being Jan and only needed about 4 hours sleep a night, he persuaded Mike to get the spanners and start stripping to get the box from the motor.
Many hours later, too much coffee further and the gearbox was back in its place, and the culprit in the bin and replaced with a new one. The culprit turning out to be a 8mm bolt about 9mm long holding the dust cover behind the pressure plate and motor that came loose. The poor replacement being fastened with enough super strong Loctite to never come loose again. Friday evening the last of the loose parts, fittings and hoses was replaced and the car started up with no strange sounds, all this drama for one bolt.

It was quite busy on the “Lil Datto” front, after some very hard thinking and analysing sessions, I decided to stretch the track on the front suspension to start matching the rear E30 parts, seeing as this could be the mayor factor in contributing to the bad front end grip. After a visit to “Datto” I decided in raiding the bigger brother of some custom made front suspension bits like, adjustable lower control arms and track rods. Armoured with the correct parts, poor “Lil” was stripped and the conversion started to get the new parts in. Unfortunately I could only stretch the track by 35mm per side as the steering arms between the inner and outer tie rods was too short to allow more. Deciding that this will be the best for the time allowed I went ahead with the transformation using my race cars parts. After making new stills and mounting points for the anti-roll bars “Lil” was put back on its wheels, poor thing had a tear of happiness in its eyes as it starter to look less like a Frankenstein car and more like a car which rear wheels will follow in the same track as the fronts. Not yet 100% in line with the rears, but as close as time would allow, fenders was cut to allow the wheels to turn as a result of the strut being moved out and to the front.

Saturday morning 04:00am, way too early for comfort, still feeling very unrested from the previous late nights, we packed the cool bags, washed our faces more than once to wake up. We preheated the tractors and got the 6 vehicle convoy going, all 3 of the tow vehicles being diesels. We arrived at Vredenburg just after 07:00 and started with the pre event preparations, I had some space available in the bakkie and decided the morning to load a mountain bike for some transport around the venue, this turned out to be one of my better ideas as I will never again attend an event without it. The track route that we were presented with at documentation, really messed with my head, after a few rounds on foot I decided it is time to tackle the route with the bicycle, man oh man, what a difference did it make.

At about 10 o’clock the event started off and more or less at the same time we realised that this was going to be one of that very special warm days down at the Weskus Mall Vredenburg just outside Saldanha.

Mike Mathee and Pietie Erasmus in Class D VW Fox 1.4i – 1st in Class D and 10th Overall

Mike was the first Race-Tech member to navigate his VW Fox thru the route, he posted a very surprising good run, something we did not anticipate. He also entered the Fox in a non-scoring run to gain experience with the new engine combination, Selina was asked to navigate for Mike to gain some experience and get a feeling of grip. After the first run, Selina must have been in shocked as she was unable to stand on her own and had to press down on the car to keep her balance. Personally I think she was shell shocked at the speed Mike went thru the course, it is quite something to sit in the navigators seat with an fast driver, especially if his times is 15-30 seconds faster than your own, it is at that exact point that you get that feeling that in the next minute you will hit something/die/roll/pee yourself etc. The expression on her face was priceless after the run, just being exposed to the speed and commitment it takes to post fast times in Gymkhana. On Selina’s own runs se made very good progress thru the day, slashing a massive 15 seconds off her 1st run, with her last outing on the route. With a little more shell shocking and practise the team will get her very competitive one day, being motorsport and not a second nature, time will only reveal the true mystery.

Throughout the day Class D was rattled and shaken as Jan, Pietie and Mike battled it out to get to grips with the cars, the day ending in making history for Race-Tech. Pietie drove the Fox to 3rd place, Jan forced his Golf into 2nd spot and Mike literally trying to destroy the Fox into 1st, out of all the previous difficulties with the conversion, This result ended in being the 1st time that Race-tech managed to occupy the complete podium in Class D. This accomplishment was the Highlight for me personally.

Herman Mathee and Mike Mathee in Class F Datsun 1200 – 2nd in Class F and 8th Overall

After struggling with front end grip the 1st round of the Witzenberg Gymkhana championship at Flamingo’s, I was very positive in regards to the track changes made to the Datsun. I decided to

use the same front 13″ semi slicks as at Flamingo’s to truly see if the changes had any considerable effect on the grip, one option was to use wider more sticky rubber, but that idea was scrapped for the bigger picture as I’m using “Lil Datto” as my Ginny pig this year to learn the 1200’s handling characteristics and carry that info over to its bigger brother “Datto”. On my first run, entering the 2nd corner I immediately knew something was feeling familiar, but better, front end grip, a smile crept in and I was able to take corners as hard and fast as with the bakkie, a feeling that I really enjoyed in the past. Immediately I knew all the hard work was paying off. The 1st and 2nd round was rough on the car, my brother and myself, every corner was over braked, overdriven, sloppy lines, but boy was it fun to have a car with front end grip, a Limited Slip Differential, a Datsun motor that is very responsive and a overjoyed driver that was enjoying wagging the tail around. The times was very good, but not good enough, I know this car has a lot more in it, it must just be found and that was exactly what I set as my next goal. This meant forget about the “lekker” and start concentrating on precise lines. Just before round 3 I told Mike that let’s try driving this round as tight as possible, and that is what he had to keep telling me. Somewhere deep very deep within me I just naturally found the ability to drive very precise lines, which resulted in a few scratch marks on “Lil” and a few leaves attacking Mike, this didn’t concern me once we heard the time, a full 2 seconds faster than our “lekker” runs. At the end of our 4 runs for the day, Mike and Myself managed to get the car to the finish 8th Overall and 2nd in Class F. My best Overall placing to date.

Jan van der Vyver and Herman Mathee in Class D VW Golf 1.4i – 2nd in Class D and 11th Overall

When we got to the Weskus Mall, it was very clear that is a course like no other. The surface was of very good nature, but there was a few bumps that was not the norm. We quickly got the cars prepared and then started to study the course. The study process was helped on my using a bicycle. It took me the better part of the first 3 runs to settle down, this could be contributed to the heat and confusing course. Luckily there was a 4 run added to the event, in which I had very good runs with very good times, but it was not enough to beat Mike, whom was very consistent and up to par on this event. It was great to take the full D class podium on the day as a Race-Tech team.

Pietie Erasmus and Mike Mathee in Class D VW Fox 1.4i – 3rd in Class D and 15th Overall

Selina Botes and Herman Mathee in Class D VW Fox 1.4i – 7th in Class D

I’m very proud of Selina, she is currently competing in the Mens class and managed to beat one of the seasoned competitors.

Pietie Erasmus and Mike Mathee in Class F Mazda 1000 – 4th in Class F

Pietie almost came 3rd, I’m pretty sure he isn’t too happy that we had 4 runs on

this particular day, as he was 3rd in Class until the beginning of the 4th, Anton managed to complete his first error free run for the day, which costs Pietie his 1st, 3rd place. A feeling that I know all too well, having lost my 1st, 3rd place at Mountain Mill Gymkhana in 2009 with an error on braking at the finish.

Hot as Hell @ 4th Lions Vredendal Gymkhana

October 8, 2010 Herman Mathee Leave a comment

Preparation started very early for this event as it is so far from our home town, needless to say, everything did not go as planned. We realized with a shock that you are not able to tow a FWD car with a limited slip differential on a A-Frame. This did not go

down well in Jan’s eyes as hê now had to drive his very stiff suspension car up to Vredendal, a 350km/h odd drive with a very bad pièce of road between Citrusdal and Calvinia. Mike, Selina and I met each other at Piketberg, attached the A frame and we set off, at times I thought Pietman was driving a fire breathing monster, the way his diesel sniffing Renault was able to overtake trucks while towing a VW Fox. Once at Vredendal we setup camp and had a hour or two left to chat with the other competitors. UP early the next morning to get ready for the action, damn this place is properly satiated just above hell, not even at 9 o’clock and the sweat was already rolling down my forehead.

Herman Mathee and Jan van der Vyver in Class F Datsun 1400 – 2nd in Class F

The 1st run went down with a good time to start the day of and no mistakes, but the dreaded white paint on the airstrip proved that they will be my biggest hurdle for the day, once I touched them my bakkie just went straight, if I’m over them the front end grip returns and I can continue in the direction that I was meant to. Just before my 2nd run, i heard the time of my closest competitor, something I do not want to hear in the future again, the time hê posted was 6sec faster than my own, I decided that it is time to step UP and drive the bakkie to its limits, well, not everything is so easy when you have corners and cones, I totally lost the plot, made a few driving errors and incurred a penalty or two, not the way to drive fast times. The 3rd and final rounds was almost a carbon copy of themselves, on the last

round I managed to post a time only 3sec slower than my competition, most definitely the most competitive day so far this season, never before was I pushed so hard to post good times, by times I had Jan holding his breath thru the last set of corners, which I took at flat foot, the best part of the track for me. We managed to end the day with a 2nd place in the bag.

Jan van der Vyver and Herman Mathee in Class D Golf 1.4i – 2nd in Class D

We broke a sweat early in the morning with the sun on our backs as we changed tyres and setup tyres. It was expected to be a gear changing course, but after the first run we knew that you only had to change to 2nd on the last bit. The weaving thru the cones again learnt us that to go slow is sometimes faster. Pushing the whole day, but we could not brake the 1 minute 4 second barrier. There is defiantly some suspension word before the next event. On the last run we also learnt that braking on the black marks from all the other cars will only cause you to go over the line.

Wet to the Bone @ 1st Neelsie Stellenbosch Gymkhana

October 8, 2010 Herman Mathee Leave a comment

Ruan was able to get his dates in order and secured himself a return ticket from Zambia to South Africa to come and enjoy his first race of the season. Just after arrival at the Neelsie Student Center in Stellenbosch, we set of with changing the street tires to some serious rubber in the form of slicks for the bakkie, Escort, Fox and a set of semi’s for the Golf. The usual small talk was made and just at the end of changing the tires around someone started mentioning that they are feeling some water, we obviously laughed this of, and figured it would be the 3mm of water predicted, o man was we in for a surprise. The 3mm predicted rainfall turned out to be 97mm of rain during the entire day of competing, something that we were not prepared for.

Jan van der Vyver’s view:
Jan van der Vyver and Herman Mathee in Class D Golf 1.4i

The morning started of with changing tires in rain, which was not any fun.
On the first class D run, we under estimated the amount of heat two bodies can produced, this ended up with fogged over windows and us not really able to see the track. The golf had us running al over the place in the wet weather. After the second run a few other D class vehicles changed to normal road tyres, for some more grip, but we new that the time lost on the second run was due to braking error on the driver side. So the decision was made to stick to the semis on front and back, now it was time to see if it works on the last run. With an spectacular run we ended up 3rd for the day in class D.

Jan van der Vyver in Class H

The class H run was used to learn to understand the wet weather driving a bit better, at the end of the day on the third run, the golf ended up to be the 5th fastest car on the day, which was al beautiful end of the day.

Herman Mathee and Jan van der Vyver in Class F Datsun 1400
After my first feel for the track next to Jan as his navigator, I realized that

it is very very wet and slippery out there, I made a decision to swop over to normal road tires on the front and rear. Slicks in my mind was just not really a option, front end grip is very important to my style of driving and with already so much wheel spin to keep under control Semi’s at the back was just not a option for the amount of water on the track. The first run ended UP in being a crowd pleasure, we pulled off. From the start line and we had to

gain momentum with a huge amount of wheel spin, exciting the first corner the rear of the bakkie slipped out, at this particular point i decided it is time to play and started working on my drifting abilities. The second run went down much beter as I tried driving without the back stepping out or wheel spinning, the times also reflected that this is the style needed for the conditions. After the 3rd round we managed to finish 3rd in the Class.

Ruan Reynders and Herman Mathee in Class F Escort MKII
As Ruan is a big believer in you use racing tires for racing and street tires for street use, I kept to his initial decision to compete with slicks, a decision I thought is crazy as the water was standing in puddles on the track. We went out the first round and had the usual wheel spin and confidence levels was low in the wet, something new to us, this car is built for dry condition, even my shoes was wet after the 1st run. Personally I think the biggest challenge for Ruan was to get his head into the game, driving in this sport is only a pièce of it, learning the track is môre important. During the course of the day Ruan got his confidence back behind the steering wheel after a absence to the sport for almost 9months, our times came down and manage to keep the car in one piece and place the car in 2nd place.

Busy day @ 4th Fairdridge Mall Gymkhana

July 21, 2010 Herman Mathee Leave a comment

This was one of the most busiest days for us as a team, not only on the day but even the week before. Björn joined Jan in die Class D Golf and they went out for a practice session on Thursday, all went good, Jan had to adopt his driving style with the new rear suspension and Björn had to get to grips with a totally new car to him.

On Friday Mike and Herman decided it is time to get the newly acquired 1974 Datsun B110 Sedan in competing shape. We knew this was a tall order, during initial testing it

felt if the rear shocks was done, front left suspension completely shot and the piece of wood under the alternator a complete mystery. We set off and created a list of things to do according to the Supplementary Regulations of things that gets checked by the scrutineers. First was the alternator, removed it and discovered both mounting points was broken, sourced one from a friend and installed it. Front suspension was checked and all fastened and the rear suspension we found the culprit, a broken shock mount, welded it in place, added some suspension stiffening rubbers to the front struts and took it for a test drive, the little car transformed from a rattling underdog to a entry level machine.

Jan van der Vyver’s view:
The golf had a very busy day, Jan on his normal class D and H entries and then Bjorn, our newest driver, also in class D. Before this event Jan had did a lot of work on upgrades, which proofed to make the day very interesting. The suspension was upgraded with Polyurethane Bushes and a stiffened rear axle. This had Jan confused as he had to content with over steer and under steer in his first few runs, but as any good driver he will have to adapt to this. It was already allot more under control by the end of the day. The occupants of the golf, had a very nice upgrade to make use of as well as racing bucket seats and 6 point harnesses was fitted to the golf. Jan ended 2nd in class D and a very good 4th in class H.

The golf took was up to his normal jokes on a new driver, and there was also a 3rd gear selected by Björn when he was intending to select 1st, but Björn proofed to have enough experience to quickly change back to first. Björn had the best day for any class D car, it is clear that Jan and all other class D drivers will need to be ready for him on the next event.

Björn Venter’s View:
After being advised by Jan at Thursday night’s practice session to arrive at Fairbridge Mall at 7 o’ clock on Saturday morning, and only arriving at 9, I should probably have expected what happened later that day. Wrong slotting on the first run of your “comeback” gymkhana career is not an ideal way to settle the nerves. But, after setting the quickest class D time of the day in my second run, I was brimming with confidence. Could I actually win my class on “debut” against formidable competition??? Sadly, I made exactly the same mistake during my final run as I made during the first, dropping me down from the lead in class D, to an eventual 7TH in class. But, I have learnt a valuable lesson, gymkhana is 50% about driving skill, and 50% about proper mental preparation. But, it was a massively enjoyable day with friends and family, and I am looking forward to the next round at the Neelsie, where I hope to build on a promising start to my “new” gymkhana career…, as a good friend of mine said: “Die wortel hang nou…”

Herman Mathee’s View:

This picture is a good example what was waiting on us in the bakkie. The times posted by the other drivers in the class was very good and we had to drive balls to the wall to be competitive. All in all it was a good day for the bakkie, on the first run of the day I noticed a huge issue with front wheel tyre pressure and was sure to correct it before the next run. Besides finding it difficult to drive the correct tight line around the obstacles and keeping wheel spin under control we did good, our last run saw us posting our best time. I cannot wait for my new machine to be finished, concentrating on riding the correct lines and not worry about inner wheels spinning wil be such a joy.

Herman Mathee’s View:

“A picture is worth a thousand words sums up this car perfectly. Since my start in Gymkhana next to Ruan Reynders in his Ford Escort MKII I have not had so much fun in a vehicle than with this one called the “JellyBean”. This vehicles was designed for grandmother to drive to the Post Office to collect stamps, I’m pretty sure Datsun in the design stages never thought some nut cases would even consider the fact to do some advanced parking lot driving with it. Understeer was easy, that did not take a lot of effort, oversteering was simplified by me on the brakes and Mike on the handbrake lever, You may ask why I could not do both, well easy, this trick bit of Gymkhana machine has so much body roll, one hand is needed on the steering the other to hold on, hence the combined effort to facilitate oversteer. I can go on for days about this machine, hell forget about your STI, GTI and OPC, this is what fun in

a vehicle is all about, pushing the limits in something that was intended for transporting stamps.

This is just one of those events that I enter light heartily, never have I arrived at this event and felt that confidence needed to achieve, properly because this is the one event on our calendar that has a track record with me. If the tarmac does not break up thru the day, it tries to tear my arms out of it sockets or has that ability to let small mistakes creep in that ends up in one little bakkie flying over truck tyres. One day

is one day that I will get to grips with you. On a more enjoyable note, I love the camping and travel that this event provide, nothing like a weekend away from the city.

Herman Mathee’s View:

The day started of with the usual, setup the gazebo, help with the track preparations and get the track in-bedded in your head. After about 7 times around the track on foot I was confident I had.

Racing started and from the get go I was not lucky with the front end grip, tyre pressure up and down, but no difference, the set of slicks on the front was done, unfortunately I did not pack spare as this is away race and space is limited, I need to get tow vehicle. Luckily I was able to get 2nd in my class for the day. Navigating in the BMW and Skyline of which the owner and driver is Kobus Wilson Snr is always something to look forward to, or should I say sideways.
