I know, I KNOW...these aren't related to forced induction, but there has been a lot of questions regarding fitment and since the blower will be excessively spinning these, it would be okay to post some pictures here.

These rear wheels are 15" x 10" with 7.5" back spacing. I have not modified of ground anything on my car to make these fit, so I think it's safe to say they will fit the LT-1 cars with stock rear brakes. I have not yet fit the front rims since the K-member is currently out of the car.
