put on the 1 inch "wheel adapters" in the rear.. really really nice. the only thing to anyone thinking about it, either buy shorter studs. or you will have to make sure that when you cut your studs they are all the same length.. couldnt figure out why they would sell unbalanced spacers. ground down all the studs to the same length and no more vibration. thanks again, i also put 7/32 spacers in the front, took away the problem with the tires rubbing the sway bars.
