I went with H&R OE Sport springs, lowered the car about an inch. Then used Bilstein HDs all around. Installed Eibach sway bars and topped it off with an Eibach strut brace and offset control arm bushings and 325 ic rear shock mounts. This resulted in a firm but still comfortable ride with little to no lean in corners no matter what the speed. This spring/shock setup increased the negative camber slightly but not to the extent of needing camber plates. This slight increase is desireable and has not resulted in extra tire wear. DO NOT CUT BMW SPRINGS!
