Hoosier Slicks And Rim Width

Mine are 5.5" Backspace, but I do have that 3/8" spacer. I'm sure the B-Body brakes I used when I went to LBP are putting the hub in some non stock position.

are you using a b-body rear? cuz im using an a-body width with LBP conversion/ b body brakes as well lol... but hey! what ever works
