I just put some 20 inch rims on my sts and the back still has a 4 inch gap between the tire and the wheel well. the front is perfect looks like 20's but in the back cus of the gap looks like 17's. anybody have this problem? i think it might have to do with the air ride.

 

The car might have to be lowered to compensate for the gap in the wheel well. Please give us a call if we can be of any assistance to you.

Thank You,
