I have the H&R sport springs and an 18/15mm spacer setup....I do daily driving off the freeways in comfort mode. When I hit the freeways, I'm in sport mode. I have the Comp Pkg and the lowered stance looks great, the ride quality is "harder" and sporty feeling. I had a 335i previously and I got KW V2's - the ride was perfect. My next setup might be the KW Clubsports
