Hey guys, i know there are a lot of posts on here about billet specialties wheels but most of them arent exactly like mine suspension and brake wise. I am going to order a set of the new street lite wheels and i know what the back spacing on the rear needs to be (15x8 with 5.5 bs) but i am a little confused about which backspacing to go with on the fronts. the choices are 2 1/4 bs or 1 5/8 bs with a 15x4 wheel. i am getting the 5 lug conversion rotors from LRS and some moser 5 lug rear axels and 5 lug frpp drums. i just dont want to do the order, try and send back routine with these. the suspension is original height etc with factory calipers. its a 91 5.0 car. thanks
