suspension

my 550xdrive m looks ridiculis, like a 4x4! i understand that h and r springs are not a good option, horrible ride and bad for the front driveshaft. can anybody reccomend a good set that wont damage the car and give you a nice ride height????

Most around here have gone with ACS if lowering is desired. If looks of the ride height didn't matter, then many others, like myself, went with Dinan.

Both springs mentioned above have several positive reviews for improving handling, but neither gives a significant drop. I think Dinan markets 1/2" drop, ACS 1".

Probably not low enough if you're going for looks/ride height, but there are a bunch of before and after pics if you search.
