You didn't mention what the height of your tire is or what the offset of your wheel is, but if it's anything fairly standard you should be able to get away with just rolling the fender.

Rolled fender lips, small amount of hammering on fenderwell, and basically removed the bumpstops. I'll probably make my own bumpstop and install it eventually, every once in a while on hard turns the tire will start to rub. I don't carry a lot of stuff in my car or autox though, so it's probably why I've gotten away with it.
