Hi all,

I’ve added a 4x scale to the suspension geometry calculator for all you boys with really long wishbones

I’m also busy with cooling updates to the car. I’ll update this site soon.

Well, here I am, back in the workshop again. I’ve had my winter holiday and given myself enough time to consider the changes required for next season.

Starting at the front, the ARB was useless and rather than transferring the weight from one side of the car to the other, it just flexed. So I have now added a 19 mm x 0.8 mm ARB and altered the drop links so they connect to the lower wishbones. Initial tests are looking good. The ARB transfers weight to the opposite side after about 25 mm of travel.

At the rear of the car I’ve reduced the length of the arms on the ARB, but the ARB is still a solid 12 mm bar. It seems to work better than the front, but I’m considering changing it.

I also noticed that when the left rear shock is compressed, the top left radius arm fowls the chassis. I’ve taken steps to increase the travel.

Mallory was a great success for me and the car as, not only did I manage to finish a race (competitively) I also got a third in class trophy so that’s something nice to have to remember the day.

The car felt sure footed, if a little tail happy in places (I’ll try and dial that out with the suspension settings). Removing the oil cooler cured the leak I had at Cadwell, but meant the oil temperature was rather high - over 100, so I need to get that back on there.

At the moment though, it’s outright speed that’s letting me down. You can see in the video how much time I’m losing on the straights. That’s a job for the winter though. For the rest of this season I’m content to get the car handling as well as I can.

As you can see the front passenger side was the first part of the car to hit the tyre wall. I’m amazed how little damage there was though as it is only fibreglass and thin fibreglass at that, but I guess the bodywork and undertray mated together made for a sturdy structure.

The car then span round and te rear also hit the tyre wall. How can both ends of the car hit the tyre wall!? The diffuser came off and split in two as did all of its mountings. Also, the towhook didn’t fair too well.

The rear wing completely detached as literally must have flown away as none of the marshalls could find it and after the race, neither could I.

Leaving all that behind though it took a couple off weekends to repair so all is good (as long as I don’t do the same thing at Mallory). The new wing comes from a Van Diemen sportscar and the profile looks more NACA than the previous ADR wing. Unfortunately, the mounting points are further apart so I’ve had to build some new towers, but they are aluminium this time so shouldn’t rip apart next time I have an off (the last ones were wooden).

The diffuser mounting has been simplified and there are new towhooks front and rear.

Also, I noticed the driver’s side front shock was leaking quite badly so I dropped it off at AVO in Northampton who fixed it there and then, for free! What a nice bunch of chaps.

Well there’s good news and bad news from Cadwell Park. The good news is that after a few glitches in qualifying and race 1, the car was starting to show some of its potential.

The really bad news is that whilst the car was showing some of its potential I managed to drive into the tyre wall at (or just after) Barn corner! The diffuser needs repairing, the front undertray needs repairing, there are a few holes in the bodywork and unfortunately the rear wing completely detached and has not been seen since! I can only imagine it flew into the lake.

So this weekend I’m repairing the damage ready for Mallory Park.
