I saved these stats from some unknown source:

C5 Z06:
Front 17x9.5", 54mm offset, 7.38" backspace
Rear 18x10.5", 58mm offset, 8.03" backspace
=======================================

From https://www.wheel-size.com/size/chev...corvette/2003/
I found the wheel size and offset for a base c5.

c5 base:
8.5Jx17, ET58mm (offset), 6.53" backspace (?)
9.5Jx18, ET65mm (offset), 7.32" backspace (?)

I converted the backspacing figures above from:

Thanks, D. I have 4.5" on current wheels (A body) sure would like to have a set when the mood comes to go corner. Guess Ill need some type of spacer not sure if thats safe or they make em that big?
