Hi,
The latest GCR has the wheel tire for C5 vettes in T-1 partly as: 17x10" (f&r), 17x11" r, 18.5" R and tire size 245x45x17 and 275x40x18. My stock out of the box C5 comes with 17x9.5 F and 18.5" R on 265 17's and 295 18's. I thought T-1 trys to be pretty stock yet by the rules my stock wheel tire combo is not legal?
Thanks!
