For a lowered 81-87 (tucked a little) what is the least amt. of backspacing I can go with without rubbing or doing any inner fender surgury . I have 5.5 now on tt2's 275x50x17 rubber . Looks like I could go 4.5 with no problem , but would rather have 4 in. What do yall think >or know .

Thanks

Will .
