C3 corvette in CS

Recipe for a L82 1979 Corvette in CS?

shocks, bars, alignment, pads, etc

Considering the cars it would be up against, just have fun? I'm not sure any amount of prep is going to help it. Bolt on some grippy tires, maybe... But even that might be tough given the lack of 15" tire choices.

Suspension will be your top priority. Stock handling is abysmal and it won't be competitive without serious suspension mods.

Are C3s rack and pinion steering?

It's drag link, but there are conversion kits available.

If he is running in CS, then the rack and pinion conversion is out. The drag link setup works well with good (new) parts. Tires are going to be tough like Ian said, not many grippy tires in appropriate sizes for a C3 vette. Might be worth while to step up to Street Prepared to run 17" wheels for better tire choices, plus the other mods allowed.

From Wikipedia 1978–1979: "The Corvette converted to metric tires with the P225/70R15 as standard. Wider P255/60R15 tires were available as an option and required fender trimming from the factory for clearance"

I was wondering how much those weighed (3,500lbs). I used to ride in the back of my dad's on occasion. Yeah that sounds like a lot of weight for 225/50R15 V710s and the 275/35R15 A6s are awfully short. R6s come in 245/50R15s which might work.

beat me to it.

I had a '76 L82 4-speed. It was fun, but tail happy in stock trim. I had 255/60/15, (street tire) they would rub a tiny bit in the front. I had the "heavy duty" 7 leaf spring and good shocks, otherwise, stock. Car did have the gymkhana option suspension.

First: according to the 2012 rulebook, stock-class cars can't be any more than 30 years old. Now with that said, I can't imagine anyone at a local autocross would care. So...

Is that fender trimming a real factory option, or a dealer thing?

What's the wheel size?

One problem you may run into is that the gearing will be all wrong because those cars were designed for tires with very tall sidewalls, and there just aren't any good performance/race tires like that anymore. So you can go with sucky tires in a stock diameter, or short, grippy tires that reduce your gearing quite a bit.

In CS you only get to change one sway bar, not both, so I'm guessing the biggest front bar you can find is the way to go.

Custom lightweight exhaust should save a lot of weight on a car like that.

Due to the car's age, braided stainless brake lines would be legal in stock.

Convert to the "Jeep" box.

Fattest front bar.

Tires? I've looked forever for 15s. If you find anything that can maintain close to the rolling diameter for less than gold LMK.

Bilsteins.

Get rid of the A/C, the spare tire and carrier, and anywhere else you can lose weight within the rules.

SP may be the better option. Especially where the rims and tires are concerned.

Look closer. That rule is only for national events they are still legal for local events.

Thanks all!

Ther are two holes in the upright/spindle/knuckle for the tie rod. I assume using the one for the fastest ratio is best?

One hole is for pwr steering, the other manual. Don't recall which is which.

True, but you can still run the faster ratio hole with the manual steer. Just wondering if it is a better autocross setup or not.

Not unless it was a factory authorized setting.
