I am confused whether 11" ZR1 A Mold wheels (5 spoke) will fit without fender conflict on a stock '91 convertible. Also, how can you tell if an A Mold wheel is GM or repro?

Thanks in advance.

I'm not sure how there would be any difference between a cpe. or a vert. in this area. A 50mm. offset should be fine. As to being able to tell the diff., on the back side of spokes it is cast in the casting w/the aftermarkets mfg./co. name. Never saw a OEM one to know what they stamp on the back, for the money I went with aftermarkets.

I am wondering whether stock ZR1 11" rear wheels will hit the fenders of a stock C4, whether convertible or coupe does not matter. Another words, is there enough suspension travel to cause a conflict with the tread sticking out with 36mm offset stock ZR1 wheels?

Also, what markings are on stock ZR1 A Mold wheels that would verify a GM original equipment wheel?

Thanks.
