Please don't tell me to do a search. I looked in 5 different forums searching for 4th gen wheels and came up with nothing.

Will wheels from a 2000 trans am fit on my 87 IROC?
Will spacers or adapters be needed to make them sit at the right depth?

Thanks for the help

 

You will need spacers. 1-5/8" to 1-3/4" should be about right.

 

will those be for the front, rear or both?

Thanks

 

Those would be all the way around. 4th gen wheels are offset such that the tire sits farther in, compared to the hub, by that distance; just look up under the car and see what that will do. I don't think those wheels will even go on that far without hittiing the brakes or something.

 

Actually check out www.Skulte.com he has a great article on what you need. Widths seem to vary for people for whatever reason.

I used 1.25" in the rear, 2.25" in the front.
