Amazing reconstruction!  :welder:  Too bad the Spyder frame didn’t make sense.

Good luck at your next race!

Just eight weeks after the serious crash into a concrete wall at the Historic Grand Prix Zolder, the Classic GP was held at the TT Circuit Assen in the Netherlands last weekend. The accident had caused severe damage to the front and rear suspension, chassis and bodywork.

The repair of the bodywork was a formality and the timely rebuilding of all four suspensions depended largely on the delivery time of important components from England. However, it was not clear from the outset whether the chassis could still be saved. To cover all eventualities, a replacement chassis in mint condition could even have been obtained, just in case. Ultimately, however, this was not necessary because the original chassis was repairable.

The to-do list hardly got any shorter, but the shift lengths got longer with each passing day. In the two weeks before the race weekend in Assen, every shift became a night shift. The rolling chassis was completed on September 1st and the marriage with the bodywork took place on September 2nd. This left ten days until qualifying on Friday, September 13, to make all the adjustments to the new front end and connect the electrics, water, oil and fuel lines. But the biggest challenge was setting up the completely new suspensions. Getting the basic settings right for the roll-out took a day and a half. As a result, the departure to Assen had to be postponed from Thursday to Friday.

The car drove the first meters under its own power down from the trailer in the paddock at 11 a.m. on Friday. Accordingly, not all teething troubles had been eliminated. A leak in a fuel line was fixed at 12:45 in the pre-start and the throttle cable had to be adjusted during qualifying. Otherwise, the roll-out went without a hitch. Only the driver's exhaustion took its toll. That's why I declared qualifying over after one reasonably clear lap so as not to risk any unnecessary driving errors. It was clear that the rear left tire tends to rub in right-hand bends. Based on this experience, the set-up could be refined.

After the essential midday nap, the rear left camber setting was adjusted. Otherwise, only the usual checks were carried out on the vehicle. Of course, special attention was paid to the renewed components, which had not yet been tested after the repair. Fortunately, all these components worked exactly as intended.

The lap time in qualifying was enough for 37th place on the grid out of 44 participants. However, it has to be said that two faster participants were placed at the end of the grid due to rule violations, otherwise it would have been 39th place. In the race, I was in 37th place on the second lap when I made a serious driving mistake in the fast left-hand bend before the start/finish chicane. I did an extremely scary 360° spin (https://youtu.be/GvQW6J3Z4Is?feature=shared), dropped back to 40th place and half a lap later the safety car came out. After that, there was only one more lap at race pace before a red flag came out after an accident involving several cars. In total, this race had only had 3 - 4 racing laps. This was very unsatisfactory for a race, but quite useful for an extended roll-out. I learned something about the limits of the car and got new feedback to improve the set-up.

For the second race, we changed the camber on the front and rear axles again and carried out the usual checks. The car felt transformed at the start of the second race. The starting lap was already close to my personal fastest lap of the weekend and the second lap was immediately three seconds faster. Unfortunately, the progression ended at this point because the grip of the soft Pirelli semi-slicks completely disappeared from one lap to the next. The feedback from the car was as if it was going to break out of control every second. So after the scare from race 1, I decided not to go on a time hunt, but to drive towards the finish in 39th place and take points for the championship standings. So the race more than fulfilled its purpose as a roll-out and damage limitation for the championship. For the season finale at the Nürburgring, I'll also have a fresh set of hard tires.

I am now back in seventh place in the Belgian championship standings for pre-1982 historic vehicles (without FIA-HTP). Unfortunately, the calculation of the points favors the high-displacement vehicles very strongly, so realistically I can hardly make up any ground with the last race at the Nürburgring. In purely mathematical terms, fifth place would still be possible. But if things go really badly, I could even slip down to 13th place. In previous years, I was 20th (2023) and 17th (2022) in the final standings.

Nonetheless, I view the race weekend in Assen as a big succes, because this accident would have been season-ending in all the years prior to 2024. To have a succesful roll-out and after that still one race weekend to go is just great.

Great job rebuilding your car. Given the damage and the rapid rebuild, to have the car run so well pretty much “right out of the box”, you did great! Hopefully with some good tires your next race will be better than ever!

Good luck!

Way to go Mecky! You've got your ground clearance lower than any Europa I've seen.

Yes, I guess, I will raise the nose slightly. The spoiler did touch some of the bumps under braking. The TC spoiler is some kind of consumable part with my car, but it doesn't need to touch the ground regularly.

The tyres aside, everything else on the car worked better than i could have hoped for after this huge rebuild. I'm very happy with, how reactive the car's behaviour is to suspension set-up changes.

My driving in the YouTube video sucks, of course. But it was my roll-out and I had neither confidence in the car nor optimized the set-up at the time. That's why the video isn't great, but it does offer a bit of action. Unfortunately, I'm making too many user-errors with my GoPro at the moment, so there's a lack of good video material.

Next time out, it will be a track, on which I have driven a lot of laps already and I have plenty of time to study onboards and drive the track on my PlayStation, which was not the case for Assen. Thus the initial finding-my-way-around-the-track-phase will not be a big issue. I hope to be closer to the pace and that I can beat my personal best lap at the Nürburgring GP track, if the weather stays dry.

The 2024 racing season is over. On 12th and 13th October, we took it to the track one last time with the BELCAR Historic Cup. We went to the Nürburgring GP circuit. The Eifel in October... You should really get a kick up the arse for this idea, but nevermind.

The weather was relatively good. The sessions on Saturday and Sunday morning were crispy cold at around 3°C, but at least it was dry. On Saturday afternoon, the temperatures almost reached double figures. The rain only came during the night from Saturday to Sunday and left a half-wet track for the second race.

Overall, the weekend was mixed. Free practice and qualifying on Saturday were still pretty uneventful for me. After qualifying, however, the car simply wouldn't start.

Cause: unknown.

Symptoms: Initially only occasional slight misfiring on an uphill straight in 4th gear at approx. 6500 /min, failed rev counter, an unusually loud switching relay and suddenly no ignition at all after switching the car off once. Nada.

As the symptoms were very diffuse and varied and time was pressing until the start of the race in the afternoon (approx. 3 hours), I wanted to rule out as many sources of error as possible at once using the brute force method. To do this, I installed all the new parts I had for the ignition and then checked all the cables and switches. New parts included spark plugs, distributor cap with finger, the aforementioned relay and, finally, the toggle switch for the ignition in the dashboard. This switch turned out to be the reason why the car would not start. The thread on one pole of the switch was broken and the screw with the cable lug had come loose. A new toggle switch solved the problem and I just managed to get to the pre-start in time. On the way to the grid, I unfortunately didn't make half a lap before I rolled out again without ignition.

So race 1 was a DNS (did not start). A major setback for the championship. The third zero-points-score of the season (two due to the accident in July) and as there are only two drop scores, this is particularly painful. But because the second race doesn't start until Sunday morning, there was still hope. There was definitely sufficient fuel supply and there was also an ignition spark. But it was apparently too weak. Luckily it wasn't a night shift, but at around 9 pm we were able to find the fault. Out of sheer desperation, we put the old distributor cap and the old distributor finger back on and lo and behold: it ran straight away. The brand-new distributor cap and finger simply no longer worked. After the engine had run for about 10 minutes before the race, I reved over 6000 for the first time on the way to the grid and it was over. These were original spare parts from 123-Ignition, especially for this electronic ignition distributor. "Never change a running system." is easy to say, but it wasn't running at the time. You always know more with the benfit of hindsight. Anyway, I was able to start the second race.

I started from the back of the grid in 42nd place and finished a very unspectacular race on a drying track in 31st place overall. Nothing great, but at least I scored some decent points. In the end, it was enough for 8th place in the Belgian national championship for classic cars. Not exactly World Champion, but a success by my standards. However, it is very annoying that the mishap with the distributor cost me 7th place. The points awarded are heavily weighted towards the overall ranking. Of course, this tends to swing the pendulum in favour of the high-displacement vehicles. That's why I can still live quite well with 8th place out of 20 participants in the national category for cars built before 1982.

Thanks for the great play-by-play! Isn’t always the case that the problem is last place you look?!

I’m glad you finally found the problem. Varied symptoms and tight time constraints make troubleshooting even more difficult.

All in all, I think your season ended pretty successfully.

What improvements for your car are you planning for next year?

Interesting situation with the distributor cap and rotor. I have seen this happen before - there are various reasons.

I do not think that I have posted this before, but my business is a plastic molding company. We are the last manufacture of caps and rotors in the USA. We mostly make US domestic caps & rotors, but I am actually talking with a 123Ignition distributor here in the States about making some caps & rotors for them. I will send you some if I can make the product.

It all depends on the spec and if I can modify or make a mold(s). A mold can cost $25K +, so low volume makes it hard to recoup costs. But, I do have a vested interest.
