Hey we can use the zr1 wheels in an 18" wheel. Corvetteguys.com shows them at the correct backspacing. I think they fit Robin used a set of Z06 style ones this month in HotRod. Use the 18x9.5's and a 295\45\18 tire and that is about the same all away around as the factory 20's. Only problem is there is not too many tires in that size.

Yep that is pretty damn close to the ZR1 wheels.

We have a winner!!!

but now i'm trying to descide between these and CCW SP20s

That sucks. Well, good thing I'm holding out to order. I might get to see someone make ZR1 style wheels for the Camaro.

Hey milk I think we are screwed on the ZR1 wheels. Looking at the offsets that are offered for the ZR1's are +56 and +61 for the 18 and 19 combo. Just thought Id let you know since we both loved the Zr1 vette rims.
