I know that e90s have more fender room than e92. I am running 19x9 et24 with 225 35 19 fronts, and 19x10.5 et13 245 35 19 rears. Maxed camber stock, and rear fender rolled and pulled. So for that size on e90, very do able. Some work required, and really comes down to the right size tires, camber, and fender rolling. There are e90 members here running pretty aggressive fitment, you can probably do a search here and see what they are doing.
