IROC and GTA wheel question

[MattyRobz]

i have noticed that some people have iroc and gta wheels on there cars. i thought these wheels were a little wider in back or had a diffrent offset in the rear to fit on the f bodys? is this true if so how are you able to make them work?

If you use all front rims you're good to go, it's the rears that have the wrong offset.

You can also use wheel spacers on the rears. I think there was a company back in the day that used ot make a set specifically for adapting the old Corvette C4 wheels to other cars that were pretty good. The bolted to the stock studs and had their own studs that protruded from them that you bolted the wheels to.
