Not sure what offset your are running, but a C6ZO6 rim in the front works well. I would guess Scotts frame would take the same. I set my car to run a C6Z06 back space in the rear as well. that way it would be easy to pick up used rims from the
www.corvetteforum.com
Anyway, go to the corvette forum and look in the C6 for sale section. Rims come up there all of the time. Normally very nice stuff in the sizes you want. That is where I picked up my HRE C21's.
