The M3 Front Control Arm Upgrade Set is a highly recommended way to easily reduce understeer and increase steering feedback for improved performance for any* E9X 3-Series or E8X 1-Series.
As the BMW community has learned, the 1- and 3-Series pack a lot of power and that can easily be increased to levels greater than the E9X M3 with aftermarket help! With that extra power potential, however, there is a need for serious suspension performance to match...
This front wishbone conversion set replaces your stock front suspension wishbone arms with Genuine M3 pieces for increased negative camber, increased steering feedback, and strengthened solid joints. The negative camber is increased by approximately .75 degrees for better turn-in and chassis balance.
Also in the package are M3 upper control arms (aka tension struts or thrust arms). M3 tension struts feature solid rubber bushings that are better performing and last longer than the fluid-filled hydrobearings of the stock non-M thrust arms.
Xenon-equipped cars require headlight link, available separately.
TRW is the original supplier to BMW for these parts, as well as many other bushings and arms.
