i got a 97 silverado and i lowered the front using djm 2" spindles and 2" coils. im getting rims soon cuz the stockers are rubbing on the lca when i try making tight turns. now the paper that came with the spindles says i shouldnt run a backspaing thats more than 3.5". the shop that im buying the rims (Boss 301's) from say they come in a 5" backspacing and they are gonna call to see if they come in a 3.5". would the 5" backspacing work or should i find something with 3.5" or less? also what backspacing can i run in the rear? its on a 6" flip kit. sorry i dont know too much about wheels. any help would be appreciated.
