New member Jim (James) Bond from Tennessee. Hoping to get a little input on some modifications on my 1966 Corvette coupe.
I'm going to start running this car in local SCCA in the new CAM class with the hope of getting a few of the bugs out and hitting one of the Goodguys autocross and the Powertour's Knoxville stop.
Some of the current details. Stock big block suspensions with old KYB gas adjust shocks and a ADDCO front sway bar. Mild 350 with hooker sidepipes and stock 4 spd. Stock 4 wheel disc brakes with o-ring pistons
Current track tire and wheel setup is 15X10 aluminum Sprint slots with Kumho Victoracers that won't comply with the 200 treadwear limit and bigger flares won't be added till the off season. I'd love to keep the 15" wheels but it looks like there just aren't any good options for tires made anymore.
I'd love some input on some lower cost mods I could do. I'm thinking some 17 or 18 inch wheels (possibly used C4 or C5 as I have a set of Vette brake adaptors) with a set of 200 treadwear tires (Direzzas? Hankook? BFG Rivals?) What's a good low weight wheel option?
Are the old style Koni's a good option or should I be looking for a more modern setup?
Anyone who has had experience setting up a C2 or C3 for racing please chime in!
Welcome Jim! I'm not a Fan of KYBs, so I'm sure that Konis would be better.
A Common Complaint is 15" Tires - The Selection is smaller but there are still some good tires available. I just bought some Toyo r888's in 15" ffor my Race Car - Sticky!
Get yourself a fiberglass mono rear leaf... or make sure your spring is the correct rate.
Dial in the CORRECT spring rate up front
Get some toe out not toe in - up front and get 3* of camber front and rear...
Get yourself a quicker ratio steering box
You didn't mention whether or not you're a road racer or an Auto crosser.... and that would determine your rear end gear ratio === so possibly a change there to make it more fitting to the track your running or driving you're doing etc.
Switch to a ligher weight flywheel and pressure plate/clutch set up for quicker rpms.
Car appears to be a '64 (disc brakes weren't standard until '65) -- so you might be running drums -- so change that out to the disc in the rear
Upgrade your Master Cylinder to a dual chamber 7/8" or 1" (depending on your preference for hard or softer pedal). The '64 had a single master cylinder.
