My cousin has a 78 c3 corvette and wants to install larger wheels on it. Whats the biggest size he could go to? All help would be great. thanks I'm a member of the SSR forum and I myself are looking for a clean C4,C5, early C6.

For your question on wheel size, The biggest I have seen on a c3 18"s at a car show!! I have a 04 SSR also 2000 VETTE!! Good luck on finding your vette!! Tim c5garage

Thanks for your help, I traded my 99 C5 for the SSR because of healing from harley crash. The SSR is a 06, but want into a vette again. But like everything need to save for it a little more. But thanks for the tip on wheels.
