1995 Camaro rim question

Hope this is the right place to post this. I have a 95 Camaro 3.4 V6, with steel wheels / plastic wheel cover. I want to know if anyone has had experience with other aluminum GM wheels fitting as far as caliper clearance, back spacing etc. For example 3rd gen. IROC, or Z28 wheels, etc. I don't have any in particular in mind but would like to get rid of the stockers.
I like the factory wheel swap thing. I run 78 Vette wheels on my 55 Chevy 210.

Those wheel look pretty nice on the 55 chevy. But to awnser your question, most all 4th gen f-body and/or 5th gen corvette wheels will work.

Actually, C5 vette wheels off a vette won't work on a 4th gen f-body. The backspacings are different. You will have to get replica wheels if you want the C5 looking rims.

I am not looking to put Vette wheels on it. Just something better than the steel wheels with plastic wheel covers. I am just partial to using other stock GM wheels is all. Its different, I want to go aluminum. I have always liked the look of the 3rd gen IROC wheels. I know the rears are different width / offset from the fronts. Looking around in the posts here I saw that the 90 Trans Am rims will fit but stick out in the back about an 1". What if I were to use 4 front IROC wheels? Any help would be great as I am more into the old school cars.
Anyone can, and allot of people do just go spend big bucks on aftermarket wheels. I have the car for sale, and I think better rims would make it more saleable is all. Also if it doesn't sell right off it will look better to me.
