Suspension setup for Autocross

[Jesse D]

Asking here as I don't see much action in the Autocross section (heck I only scrolled down that far for the first time  last summer). Move to the autocross heading if appropriate.  I have a 1993 Caterham HPC with a Vauxhall that I have been autocrossing the last several years , using Avon slicks on 13x8 wheels with a square setup. Last summer my grandson joined me and we are working on the setup of the car. I drive maybe 1,000 miles on the road for fun . Our locations are bigger than most- a racetrack in NH, Loring AFB with a 2 mile runway and the apron of the old Navy airport in Brunswick. I just bought a new de Dion rear end and a wide track front end with new Nitron adjustable shocks all around. We have hub stands, plates and scales and I'm looking for toe in and camber settings mostly. and any other advice. I have no idea how it was setup before and we have replaced everything.

 

As an aside, SCCA has begun running events in Brunswick, so they consider it a good location if anyone wants to come to Maine in the summer. Loring is a long drive but an amazing place (an abandoned SAC base) and Northern Maine is unique.

Are the tires radial or bias ply?

They are Avon AV3146s, which I believe is bias ply. On their second year, I bought them from Roger Kraus just as Avon went out of business. Replacement is one of our issues at some point this summer.
