what kind of tire are you running? Some 315 brand tires run smaller the other 315 tires, do you have adjustable panhard rod? that will help with centering the rear end up some. You may have to do the BFH mod (big f***ing hammer) with the inner fender wells, and you may have to roll the inner fenders lips also because you may have rubbing issues also. Modding also varies to which rims you have, some rims have more offset then others, meaning that some wheels may further out the fender well. IMO, I would either the BMR springs or the Hothkis springs, they are about a 1" drop, so if you do have rubbing issues, they won't be as major as running the pro-kit, which some say sags in the rear BTW. Are you running stock shocks also? Aftermarket shocks may be stiffer then the stock shocks, which will also help in minimizing suspension travel, which will reduce rubbing in the rear also. Just some things to think about
