Well done Tony, that is a big change to go to the 15" rims on the Corvette and for some (not sure if this is case for you) it could mean brake changes to allow for the 15" rim fitment - a cost that might not be as simple as new rubber and rim. This could change the Corvette grip level too.

If we have more do this - change their cars to meat the rules (Ricky changed from 16" rims down to 15" a while back, and I have seen others do the same over the past 12+ months) then we will have more compliant cars out there it might facilitate others to change too ie remove their sequential gearbox, cosworth engines, EFI on cars never sold with EFI.
