Why are some of you installing spacers in the front? I've got 343's on my 2011 550i with 255/35's in front lowered with ACS springs and have absolutely no rubbing of tires, fenders, or brake calipers. Yeah, they're really close, but the back of the rims are notched to allow for caliper clearance.
See this thread.
