Re: Grand sport wheel offset ? (millerconsulting)

I am not sure what the backspacing # is. I do know that the stock Chevy spacing is fine for use on a C-5. I run a set of stock sized AFS grandsports on my 2001 for the race tires. I use the Kumhos in stock GS sizing and have no clearance problems what so ever. Hope that this helps. :D

Re: Grand sport wheel offset ? (millerconsulting)

gs wheels are 7.5" backspacing in front (9.5") and 8.875 in the rear (11")
a c5 has room to go up to 8" in the front and 8.75" in the rear
most of the t1 cars run 10" front w/ 7.5 and 11" rears w/ 8.25
m/cup sgs cars run 10.5" front w/ 8 and 12" rear w/ 8.75

:confused: Are you saying the 17x11 gs wheels will not work in the back. I have them on my car now even using the functional Z06 brake ducts.

Thanks,
