I just googled these an found them,hey maybe you could help me i have a 91 convertible an was looking to get zo6 rims aswell 18s an was pretty much wondering if you knew what size adapters work best?...im just looking to make sure the wheels wont stick out really far if you know what i mean.
Any help would be awsome thank you an i hope the picts help.

 

im not exactly sure but i know you need 2" adapters to put the 4th gen camaro wheels on 3rd gen. so im going to guess you need those maybe a little bigger in the back depending on offset and backspacing. and thanks for the links
