dude, get your flame suit on. you should have did a search. :p
long of the short, the problem is not so much lug pattern or backspace/offset; its caliper clearance. The OEM rim has a sort of built in spacer to aid in caliper clearance.
The only "off the shelf" rims that fit without spacers are from discount tire, the MB series. predators and gunner 6 I think fit. thats about it.
if you want more options, do that search thing I mentioned
