I have a pair of Genuine GM chrome 17x9 (or were they 17x9.5"?) SS 5-spoke (ZR-1 style) for sale...
A little curb rash on each, but no chrome flaking or any other problems... Would be great for a set of drag wheels if you own a SS or a set of these wheels...
Still have factory GS-Cs mounted on them with a little tread left (not bald by any means), as well as SS chrome center caps...
