These were marked 53mm on the inside of the pad but still it's more than I want. Thanks for the info.

From everything I can find, the C5 Z06 rear wheel is actually 58mm offset, not 53mm. Based on that, I change my previous thought. The C5 Z06 rear wheel (18 x 10.5, 58mm) may or may not work, as it will give you almost 3/8" LESS clearance on the inside. Depending on your sidewall, that may be close.

So, based on the specs alone, I agree with Bryan that the C6 Z06 Front wheel should work, but the C5 Z06 Rear wheel might not.
