Has anyone tried a C5 or C6 Z06 18 or 19 rim on the front
of a 2009 CTSV? If so, what was the outcome? I'm sure
alot of the V2 owners are looking for more optional rims.

Good question..I'm listening.

totally wrong offset. They will not clear the brakes.
I had a c6 z06 with spec multi wheels that i would have liked on the V but not even close to fitting.
