Need to clarify there is a difference between OE Wheels and OEM. I don't recommend the OE wheels-they are heavier and I don't know if they are as strong as the factory original OEM wheels. Get a set of used OEM 17" wheel whether the 10 Spoke SS or the 5 spoke ZR1 style. You can find sets of 17.5x9 Z06 wheels but they are going to be about double the cost. They aren't going to make much of a difference other than looks for you.
