Wills 18"s fit on my '83 z28?
I've been looking into buying a set of American Racing IROC replicas for my camaro and I wasn't sure if they would fit. The websites that I've been looking at don't offer info for anything older than '85. Since my Z came with 15" wheels I wasn't sure if the oversized 18"s will fit. If they won't, will 17"s work?
Also will I need any spacers or anything to make them work?

what width are you looking at? if you can buy the wheel with the correct backspacing/offset, then you dont need spacers. You can bolt on any sized wheel that will fit in the wells, many many people, myself included run 18's, there are even some 19 and 20" wheeled cars on this site that look just fine and the wheels fit no problems.
Just remember bolt patterns is 5x4.75

Both the AR IROC Chrome 7 x 18" and 8 x 18" will bolt on just fine without any spacer required and look great.
Go with the 8" wide rim and a 245 40 18 tire. It will match your old tire height perfectly so your speedo won't be out.
Good luck.

I've looked and haven't found them in 17" but I think I remember someone commenting on 17" IROC replicas. I'd rather have the 18s anyways so it works for me.
Thanks for the help guys.
