I'm not a big fan of the rivet look. If they were regular Chrome Z06 wheels I can dig that.
check out this place too
www.aaarims.com they have a nice large selection of f-body wheels.
I think you should get the new new Z06 Wheels (I think their 18's)

I know their for sale because Ive already seen them on a few cars, and I think they look pimp.
