As the BMW community has learned, the 1- and 3-Series pack a lot of power, especially on the turbo engines, that can easily be increased to levels greater than the M3! With that extra power, however, there is a need for serious suspension performance to match. Installing a full set of E90/E92 M3 suspension arms adds negative camber and gives your BMW stronger bushings and ball joints. These will improve handling, reduce understeer, and improve steering feel.

This set of OEM aluminum M3 control arms, wishbones, and guide rods are a direct replacement for the stock front and rear arms on your E82/E88 128i, 135i, 135is, 1M (2008-2013), E90/E91 325i, 328i,330i, 335d 335i, M3 (2006-2011), or E92/E93 328i, 335i, M3 (2007-2013) - RWD models only. OEM M3 suspension arms are made by TRW.

OEM Front Control Arms: 
This front control arm set replaces your stock front suspension wishbone and tension arms with OEM TRW 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. These M3 upgrade arms can be used with the stock, non-M suspension on both E9X and E8X cars. Kit includes left and right upper tension arms, lower wishbone arms, and includes the M3 headlight leveling arm (you only need the bottom stud from it).

One of the key advantages of the M3 arms is in the bushings. The tension arm bushings are not filled with fluid like the non-M stock bushings (which tends to leak out). The solid rubber design make them stiffer and last longer. The wishbone has a sealed inner spherical bearing that provides much more precision.

On cars with xenon or adaptive headlights, the original non-M headlight leveling arm cannot be re-used. We include the M3 arm in this package. Remove the lower ball joint/stud from both arms and use the M3 stud on the non-M arm. Secure with the included M6 nut.

OEM Rear Guide Rods:
The M3 aluminum guide rods that are stronger and lighter than the stock stamped steel. The bushings are also more performance oriented - inner sealed monoball bearings and outer solid rubber bushings. These bushings will not deflect as much as stock rubber, keeping your alignment in check. 

OEM Rear Wishbones:
The M3 upper wishbones replace the standard E90, E91, E92, E93 upper wishbones. The inner M3 bushing is a sealed Teflon-lined spherical bearing for smooth suspension motion with near-zero deflection. ABS sensor brackets included.
