I have a set of Corvette C5 Z06 rims 18x9.5 inch wide fronts 18x10.5 rears. They are currently chrome with a few curb scratches but I offer Powder Coating if you want it.
Asking $200+ shipping as is, Powdercoated depends if you use an in stock color

PM me for photos and inquires,
as for powdercoat colors i currently have

Florescent Green
Florescent Pink
Bright Red
a Darker Red
Siberian White
Black both Gloss and Matte

Willing to aqquire different colors if these don't suite you.

Are they GM wheels or aftermarket? If GM I'll take them.

The Z16 (anniversary edition) were polished, but that's the closest thing GM had for chrome z06 wheels.

And real GM C5 Z06 fronts are 17"

Yeah i knew that, figured it was a long shot that maybe someone had there gm wheels chromed.

Ok since my info is wrong ill update the description of these rims. They are replica's I believe they have the fake bolts on the edge they are still chrome and my dimensions were correct as well 18x9.5 and 18x10.5 I do have photos upon request I forgot how well they actually look.
