"Suspensions I assume are the same?
How much power is reliable through a reasonably stock driveline?
Can you actually get a roll bar in these things or is a convertible superior?
How much tire can I get on a stock chassis? I don't care if it rubs a little.
Stock weight?
Who is the #1 aftermarket source for budget suspension?
How many seconds per lap will I smoke a 1969 Ford Torino with sub par equipment?"
1. Suspensions are interchangeable for all chrome bumper cars. The 68 has some unique stuff but mostly body and interior pieces.
2. Autoweldchassis.com makes roll bars and cages for the C3. The car may fit a small gym bag and a box of kleenex once a bar is installed. The luggage rack on the back will have to be used for traveling.
3. You can get a 10" wide wheel under the car or go with fender flares. Duntov makes L88 flares.
4. Stock weight is 3200-3400lbs
5. VB&P and Sharkbite suspension systems will bolt on to a stock frame. A top of the line Sharkbite will run $10k but have all adjustable suspension, steering with bump stops, and C6 Z06 brake package.
6. Stock drive line is good to 500-600hp, maybe more if you dont drag race. Duntov has some upgrade options and several vendors have other upgrades to include a solid axle.
7. Custom chassis with C4-C6 suspension and rear diff are very common with SRIII and Street Shop vendors being the most popular. A Custom chassis with C4 stuff is $20k with C6 at $25k or so including a fuel tank. Tubbing kits are available to put 12" wide wheels under a stock body but can only be used with a custom chassis.
8. Decide early on whether you are going to upgrade your current frame or go after market chassis. Resale between the two will be vastly different as modded stock is worth less.
9. Very few after market seats will fit in a C3. Corbeau A4s fit and have custom rails for C3 installation. If you 6' tall or more, buy the short rails for a little more head room.
I did a C2 with custom chassis and am planning a C3 with upgrading the stock frame. Join the Corvette Forum and hang around the C3 section and the road racing section, lots of good information. Not all vintage Vette's sit in the garage waiting to be polished, lol.
The Camaro Gen 3 mullet is not an option for cruising in a Corvette, but polyester pants and white loafers are ok.
