OK I think everyone can calm down now.
Anyway, a 225/50R17 (stock, right?) and a 225/30R20 have basically the same diameters, so if there's no rubbing problems on stock with that drop, there shouldn't be on the 20's. Of course, the 20's have a much rougher ride, and I have no idea if you have a width difference.
