18x8.5" & 19x10" Corvette Wheels - Late C6/C7 Fitment

Looking to grab an autocross/track wheel set for my C7 Z51, the tire sizes suck for the 19/20 setup that comes factory on the car.

Specifics: 18x8.5" fronts & 19x10" rears from a stock base C7, but some of the late model C6 “gumby” wheels appear to fit also.

Let me know if anyone’s trying to move any of these things.
