Thanks Jon. We already have a proportioning valve and found very efficient pads. I really think the problem is the caliper but on the other hand we can't have the braking power of later german cars !

There have been Ford racers who have had their 4 piston caliper cast in aluminum...... doesn't work, it's not stiff enough in aluminum..   I'd have to guess there's something askew with your brakes, (or pads, or master cylinder..)   I don't think you'll ever stop with the smaller/later cars, but the Hemi Cuda reference tells me yours aren't right...    Ken

You are probably right. We will try to sort that out next week-end at Dijon.

PS. A rather extreme solution would be to have the Corvette caliper halves cast in aluminum, then some machining (and cast blast paint?) ..  and SS sleeves and aluminum pistons and you'd greatly reduce the weight, but I think they would still weigh more than 2 lbs??   

I have to say I would love to go for this solution. Do you know if anybody here on the board has ever heard of someone having done an aluminium cast of the Delco Moraine calipers ?

Well, the fact is they brake but we fight against younger / lighter cars like BMW CSL, 635 gr.A, Capri gr.2 and the braking distance we achieve is ridiculous compared to them. Even the heavier Hemi Cuda seems to brake better than our Camaro.
Better period correct calipers would be Girling and maybe the hurst-airheart but I am not sure. And I would have to prove they have been used in period on a Camaro if I want them homologated by the FIA.

How can heavy calipers be beneficial ? I have heard that alloy calipers would save around 36 lbs !! But again I have to prove that alloy calipers have been used in period if I want them FIA homologated. Not easy !

Few picture of the post race parc ferme packed with touring cars.

Is that a red Camaro with white stripes that I see in the distance in one of your photos? Looks like possibly another '67?

Yes it is a 1967 Camaro Z28, the Heinrich Chevy-land one which now belongs to a Belgium owner.
We also had several US cars in the grid : a 1978 Camaro Z28 that competed 8 times in the 24 hours in period, a 1970 Hemi Cuda, a 1968 Mustang 302 TA recreation, and two 1965 Mustang 289.

Great photos!  I Love them... and Congratulations on your finishes!

What are you running for brakes?  and do you have a plan for improvement?

We have the JL8 brakes with Delco Moraine calipers. They don't overheat but they are heavy and the braking distance is average to say the least. We have no plans for improvement for now, as we have to prove that any system has been used in period to use them on the car and be FIA legal.  It seems the Girling  alloy Calipers have been homologated at some point but we have no trace of them being used.

Spa Classic is now behind us. It has been an epic week-end with two races of 1 hour each (1 at 3 pm and one at night ). With 40 entrants and a stronger field than ever, we are very happy of our results : 12th in the first race and 9th in the second race despite little ignition issues that led us finish the race on 7 cylinders !
The Camaro pulls hard as usual but this time I think we have found the right chassis setup. The handling is much better now and is quite surprising by many who see the US cars as straight kings.
Brakes are consistent but the braking distance is one of the worst of the grid. I guess each car has his drawbacks !
Here is a link to a cool onboard video and article by the guys at Goodwood Road and Racing Club :

Few pictures of the races. Spa is just stunning !

We are getting ready for the next round in Spa. A big event that even includes a grid with historic Group C cars.
We will have the pleasure to race twice, 1 day race and 1 night race (1 hour each) to recreate the unique atmosphere of the famous Spa 24 hours races back in the 70's-80's when touring car racing was so popular.

A new clutch is installed, following our frustrating first round at Vallelunga.

We will also fit additional high beam headlights for the night race in the style of the Camaros which raced in period in the 24 hour race. See few of them here under :
I will keep you posted with hopefully great images and footage of the race (22-24th May)

Thanks Dale.

I had made some research prior our first season on the best threaded tyres to fit to our Camaro. A vast majority of guys here in Europe use Avon Cr6ZZ even on dry surface. I have to admit I don't know about the Goodyear and have heard that the Hosier are not that good. Do you have the reference of the Goodyear?

What engine size are you allowed in this series?

Robert

As my car is homologated as a Trans-Am car, the limit is 5 liter.

Thats awesome Eric! The two vehicle is pretty cool too.

Do you only get one race per event?

Yes unfortunately 1 race per event (1 hour), except for Spa (next round 22-24th May), where we have 2 races, 1 day, 1 night, to reproduce the glory days of the 24 hours of Spa.

Can you give some specs on your wheels and tires? I have been confused about what kinds of old school wheels are actually strong enough to race on, and you are running the exact wheels I love the most...now I just need to know who makes them!
Thank you so much.

As Steve stated, PS Engineering and I use Avon CR6ZZ tyres, the best threaded compound available for road racing we have found.
