ok so here i go, im new at this so hopefully i can get some help. i recently bought a 3.5'' lift for me WK (rockcrawler bolt-in) my take on the lift is it has a strut extention in the front and a spacer in the back. i might be wrong. my qeustion is on the wheels, i know i want the rockcrawler black wheels 17'' but i have no idea what the lug nut pattern and backspace is, if someone can help that would be great. also has anyone heard any bad things about the lift i bought? on the website (jackit.com) i bought the lift from it said i can put 31'' tires on with no rubbing please help me !!!!!!!1
