Depends if you want genuine GM wheels, or replicas. GM never actually chromed the Z06 rims, so people take their OEM rims and have them chromed. This is more expesive than buying an overseas replica that looks like the original wheel. These are usually less expesive and a bit heavier. There are places selling a set of 4 new replicas for under a grand. The replicas are usually SAE approved, but usually do not go through the same testing & quality an OEM rim does. You can quickly tell by looking at the back. Additionally, I believe at least one year of Z06 wheel was forged, not cast. That usually makes a better wheel. That said, now you are hopefully better armed to go looking.
