I would like to use Hoosier "A" tire in 295/35/17 F and 315/35/17 R on my C5 for SCCA autoxing. I believe I would be in class ASP(?). Anybody know what wheel size to use? I've been told the C4 wheels 10" F and 11"R w/the Grand Sport off sets would do the trick. Will Camaro wheel work? What are the req'd. specs. for the offset/setback F and R?
Am I on the right track here? (Not intended to be a pun.)

17X11 rear GS wheels have 50mm offset. 315 fits nicely but sticks out a little.
I think 17x9.5 has 54mm or 58mm offset

I run the GS 17 X 11 wheels on on all 4 corners w/ 315's on my C5 FRC with no problem. They stick out a tad, but no rubbing issues.

Stock Z06 sizes. 9.5 17s and 10.5 18s will work. Nevermind, I see you want 17s on the rear.

On my car there is one rubbing issue with the front 17 x 11s. The rims touch the control arms on tight turns and do a nice job of removing the balance weights.
