Default 1976 corvette autocross project

Hi guys Iím new to this forum. Currently have a 76 Vette Iíd like to make a street/autocross car. Iíve got a new 750 Holley carb, 4 bolt main cammed 355. Is really appreciate some input on upgrading the still stock suspension. I donít wanna go cheap at all but Iíd like to do the project little by little without making the car unusable and without completely breaking the bank. Any info is appreciated. Let her rip!

Does the autocross group you run with have any restrictions on modifications that wont effect what class you run in?
Do you have a maximum dollar amount to invest?
A cheap place to start is front and rear sway bars and shock absorbers.
Beyond that increasing wheel and tire width.
Going further would be front and rear spring changes.
Still further would be complete changes to the type of front and rear suspension.

Though they do occasionally host an autocross, race tracks like Lime Rock Park and Stafford Springs, don't usually have autocross'. You'll find that normally they're held on a parking lot, through a course laid out using safety cones. Even when an autocross is held at a race track, they often only use a portion of the track, and may still lay out the course using pylons. My local Sports Car Club of America Region (SCCA), holds 10 or 12 solo events a year, one or two on track at NJ Motorsports Park, and the balance on a parking lot in Atlantic City.

Before deciding on what modifications you want to do, you really should reach out to some of the local SCCA Regions, and/or other sports car clubs, such as Porsche Club of America (PCA), to see what classes they run, and what modifications are allowed.

Your best bet might be to show up at an autocross, watch, ask questions of the organizers and participants, and maybe even enter your car in it's current stock condition, to get a feel for what it's like and to have a baseline for the future.

I did a lot of autocrossing in the 70's and 80's, in Corvettes and other cars, and really enjoyed it. My avatar picture is me autocrossing my 62, around 1978.

Something to keep in mind is that in autocross, aside from seat time, tires are the most critical element to making the car turn respectable times. It's important to understand that the best tires for autocross are not manufactured in 15" sizes appropriate for Corvettes, the 15" sizes are all very small for Miata's and such. The various organizations that host autocross have unique rules to allow 1" upsizing or downsizing the wheel diameter to open up tire options (SCCA, while NCCC allows +/-1" on diameter and width) and still stay in stock class. Going to 17's or bigger will bump you out of stock into a modified category, which is fine if that is what you want to do. If you run SCCA and plan to upsize wheels to 17" or more, you might want to look into the CAM-S class (Classic American Muscle-Sports), which allows for almost any modification but is restricted to high performance street tires (200 TW such as BFG Rival S or Bridgestone RE-71R). The drawback to CAM-S is that it allows Corvettes all the way up to current models.

Just make sure your tires are in good shape, maybe add a few psi to keep them from rolling over. Fresh fluids and you should be in good shape. Have a good attitude going in, realize that you'll more than likely be humbled by somebody in a grocery getter Honda or Mini Cooper. Other than that, focus on seeing the course, don't get lost and improve your times run over run. And have fun!

Is that something I should look into? I was wondering if Von steel was the way to go?

What are recommendations for new shocks? Iím thinking about getting the whole set of Bilstein sport shocks as my next upgrade.

Bilstein Sports would be a great choice.

Check out our thread on these and what it takes to make them fit.
Posted same info on the guy's Facebook page.
Buyers beware.

23 pages of information in this thread here......
Better have some skills to make them work. Welding, machining and re-coating all needed.

THESE are what the real Global West look like.
Notice the Global West label, the different ball joints and the real giveaway......the cross shaft on the real ones are a direct bolt on. The ones on the FB guy's need serious machining.

In addition to reading the rules, before you start throwing money at mod's I recommending reading up on these suspensions. They are unique and the more you learn, the less chance for making huge errors. This is a very good article to start with Vette Improvement Program (VIP).

Other good articles can be found here http://www.corvettefaq.com/c3/

You don't have to spend a ton of money to get C3's to handle quite well if you can turn a wrench and do some light fabrication.
