Sounds cool. 10's up front are easy. 12's in back are easy, but if you want to go ridiculously aggressive, you're going to have to get rid of the hump under the door in the fender. I'd think you'd have to have it cut out and welded back flat. I had a body shop try to hammer it flat and that bump won't roll or hammer flat. With aggressive offsets, you'll rub right there even if the rest of the quarter is rolled flat. If you just want to hard park on air, it won't matter. But if you want to drive low, that bump has to go or else it will rub non stop. The FX is really reinforced under there so the fender roller only does so much, you can't pull it like on other cars.
