Just a quick word about the spacers. If you did'nt know lug bolts or studs have a torque yeld for aluminum wheels. Meaning the studs "stretch" to maintain a positive pressure against aluminum wheels. Cucv's and any other car/trucks that came with steel wheels dont have yeld studs there studs are hardened for zero stretch. The steel wheel itself compreses just a bit to allow the lug nuts to hold at torque by the "spring" pressure of the wheels. If you have a truck that came with aluminum wheels you can use steel wheels instead becuse the stud yeld will hold it at torque, but if your truck came with steel wheels and you put aluminum wheels (or spacers) then there is no yeld from the wheels or studs. You can do it but your way more likly to have cronic lose lug nuts or even fatige the aluminum to the piont it gives. Iv seen cars with rims put on even though it came with steels and hub caps and no mater how much you tried to torque to spec the aluminum just ozed out from around the nuts. Becuse the studs were for steel wheels and refused to stretch. Though i will say the spacers look like a good big chunk of metal id sleep alot better at night with a large washer and lock washer to help hold the spacer to the truck. The best thing to do is to recenter the wheels, its cheap insurence when you think about the spacer coming loose and your tire thrashs around, riping its self off sending you rolling over and over on the high way. Then smashing in to a barrier throwing you off an over pass then landing on the tracks of an on coming trian.......thats a worst case scenario but i think you see the point. Like i said you can do it but its illadvised or you could swap out to yeld studs and its good.
