If your 335d needs new bushings this kit is a great way to refresh them and upgrade at the same time.  Includes a set of four front control arms and the headlight adjuster used to convert the standard 335d control arms to the more robust M3 control arms. M3 control arms feature solid (instead of slotted) bushings in some locations, and replace the inner front arm bushing with a spherical joint. They also allow an approximate 0.8 degree increase in negative camber, improving turn-in and cornering grip.
