Sorry for the late reply on an old thread.

If the Koni double adjustable seemed to be the one to use in Trans-Am back in the days, what about today ?
In your opinion what is the best front shock to use today (TA legal) ?

It seems that if you have to run against cars that are racing on slicks, there shouldn't be a problem with them letting you run with aftermarket calipers like the kind offered back in the early '70s (Girlings, Hurst-Airheart, etc). This was legal in Trans-Am beginning in the 1970 season.

Jon,
what type of Girling calipers where used back in 1970 ? Would you have any period picture of these calipers, preferably in international racing (I might ask too much, I know :-) )

Thanks for the info, Jon. Unfortunately the only brake calipers that are homologated are the Delco Morraine.

The ride height on the rear is little high on my car. Would you use lowering blocks to lower it ? Would there be any benefit in terms of handling ?

Unfortunately not, hence the purchase of the M22.

Yes it was advertised with a Jerico but I bought a rebuilt M22 from the seller.

The BMW are allowed to run slicks as any car from 1972 on the grid. This is a big advantage as we are using threaded tires (Avon CR6ZZ).

As for the brakes we did go through the caliper seals and installed Willwood racing pads. Now it brakes, but I am sure it still can be improved.

Yes it is.

This was our first race this past week-end in the Heritage Touring Cup championship on the ex. Formula 1 track in Dijon (France). For those who are not familiar with this track (there might be some), here is a link to the most famous Formula 1 battle in history in Dijon in 1979 between Rene Arnoux and Gilles Villeneuve : https://www.youtube.com/watch?v=4pMkYK2d_GI

As for our race, we qualified 8th out of 25 cars which was a big result for a first race with the car. The BMW CSL are too fast for us but the car was surprisingly well balanced, sliding but not too much. We solved the brake problems and are now trying to improve them a bit (this is the weak point of the car).
For the race, due to two withdrawals following engine problems, we started 6th, and passed an ex.works BMW 635 Csi on the starting line, getting on 5th place in the first lap ! Unfortunately an electrical problem in the second lap cost us 20 minutes. We finally fixed the issue and finished 10th. I have to say that only 10 cars did finish the race ! Anyway, it was already an achievement to finish on our first outing.
The car is a blast to drive !

Few picture of the event :

Yes the pedal is soft, no need to warm up the pads, things remain the same when hot. Will pass to my mechanics your advice on the rear axle. Thank you.

I use the 1 inch master cylinder.

Thanks Jon.

Robert, the symptoms are as follows : No power on first brake, then the car slows down but don't really stop. On the test track we tested the car I went off the track several time at the end of the straight even when braking very early. We know the brake pads we first found are crap (don't want to mention the brand but they are made in UK). We will switch to Wilwood race pads that seems satisfactory to the Corvette guys we met here in Europe.  What's more my mechanics has spotted a leakage on one caliper, hence the need to go through the seals (I have ordered the O ring conversion and rebuild kit from Css).

As for the brake cooling ducting we have had no time to build and put them bit this is the plan, at least for the front. No power brake system.

Yes Delco Moraine Corvette calipers. Don't know if they are fitted with heat insulator. How could I tell ?

Yes I have done some shakedown runs. The engine is superb, handling far better than I expected but braking is awful. I will switch to Wilwood racing pads and go through the caliper pistons seals and hopefully it will get better.

As for the hood pins, I don't know, it was done like that and I did not change it.

A promised, here are few pictures of my car.
