Things just got interesting., page-6

I will comment on the validity of the Ebay listing..

They have a GM part number and a US Department of Transport number. The C8 Corvette Z06 test mules have been running around with odd, very large wheel coverings (they usually just paint the wheels black). The CBR wheels above are huge (21 & 20 inch). They're certainly not fake images. GM does not like being one-upped by their cross-town rivals at Ford.

There is no doubt in my mind that these wheels will be on the C8 Corvette Z06. The only question for me is, will they be an option (like on the Mustang GT500), or will they be standard fitment (like on the Mustang GT350R).
