If the tire is the same outside diameter then he can run 15, 16, 17's, or 18's and not rub any more or any less. Go up a wheel size then you have to go down a size in profile. It's common sense and simple math.

Without having an adjustable suspension ie: coil-overs and camber plates it will be difficult to fine tune the stance, especially with a deep offset wheel that's going to stick out. If you want the tucked, poked, stretched look and everything then you have to be willing to pay for quality suspension components to prevent body roll ie: sways and high quality coils & dampeners other wise you end up with dented fenders and shredded tires.

There is nothing more irritating then having a cars tires scrub because of improper fitment and inferior components!
