I'm rubbing quite a bit both front and back. I don't have rolled fenders as I think the rubbing is inside the fender well. I'm going to try stiffer shocks (Koni Yellow Sport) to see if it helps and will let you know. Otherwise, coilovers may be the solutions.
Koni Yellow Sports is def one of the best choices. Was thinking about coilovers but didnt want the harsh ride. I dropped my E90 today on H&R Sport springs, Koni Yellow Sports shocks, rear 15mm MS spacers, & front Hotckis sway bar. Im rolling on 18"s(8.5"s front, 9.5"s rear) BBS RS GTs. No rubbing issues at all. No wheel gap. Decrease body roll greatly. Difference of night and day with new setup/wheels.
