Thread: 1985 grand prix wheel offset?

I'm pretty sure their 5x120.... but I'm not 100%

3.5-4" backspacing works well depending on tire size and rim width. What size wheels and tires are you planning to use? Most of the newer age rim styles wont work on G-body cars but there are still a lot of wheels to choose from. Centerline will custom machine any offset you want but they are on the pricey side depending on style.
