I am going to get the 4" PRG performance lift and wanted some advice on a wheel and tire package I found. The wheels are 18x9 1/2" and have 4 1/2" of backspace. The offset is -19. the tires are 33x12.50 Nitto Mud Grapplers. Do you think I'll have any rubbing issues? Also, I don't want a wheel that sticks too far out. Any input will be appreciated. I am pretty set on the Performance lift with SAW coilovers, PRG uca and DR or SAW rear shocks, but am still considering the 6" Procomp and adding the goodies later. the 6" would definately mean 35's. Are any of you disappointed with the amount of lift from the 4" performance kit?
