This is the info of the wheels i am looking at

Size: 18X10
Finshed: 1-Piece Painted/Machined Alloy

Backspacing: 7 1/8
Available lug patterns:
5-4 3/4
Offset: +30
Backspacing: 6 3/4

Will they fit my f-body? I want something classy, and great looking, black AR rebels are what I'm looking at.

 

You need the 5x4.75" (120.65mm) bolt pattern for a 4th Gen.

The 41mm offset will work in the back, with the edge of the tire tucked just barely under the fender line. In the front, its probably going to stick out past the fender line. To decide if that's the look you want, go to the FAQ, scroll down to the post about fitting 17x11 wheels on a 4th Gen, and click on the pictures that show the 49mm offset 17x9.5" wheels. The 18x10's will stick out 1/2" more than the wheels in those photos.
