Are 15" & 16" interchangable

I have an 89 RS with 15" rims and an 89 IROC with 16" rims.
Is the bolt patterns the same on both?
I'm curious, if I needed a temp spare if I could put a 15" rim & tire on my IROC?

Thanks

The bolt pattern should be the same. If u have limited slip diff, it is not a good idea to have different size wheels on the rear axle. Tends to eat up the posi clutches.

if you do have to temporarily change the rear wheels just take both sides off the other as well. they are exactly interchangable throughout all gen 3 years. whether its rs, z28, or iroc lugs are the same.
