Millway Motorsport rear trailing arm outer spherical bearing kit for BMW E82 1M, E9X M3, E8X 1 Series and E9X 3 Series. Upgrade the rear axle with a motorsport-grade rose-jointed RTAB outer conversion that replaces the soft factory bush to remove flex, sharpen response and lock in consistent toe control on fast road and track cars.
This eccentric outer joint gives valuable alignment range for lowered cars and coilover setups, helping you fine tune rear geometry for stability, traction and confidence. Expect cleaner turn in, predictable rear end behaviour and repeatable performance under braking and power. A proven choice for BMW chassis tuning, time attack, track days and spirited road driving.
Main advantages
- Spherical bearing design eliminates bushing compliance for immediate rear axle feedback
- Eccentric housing provides extra adjustment to optimise toe and rear geometry on lowered BMWs
- Reduces rear steer for calmer high speed stability and improved mid corner grip
- CNC aluminium bodies with stainless spacers for strength and durability
- Direct replacement for the OE outer trailing arm bush, ideal with performance springs or coilovers
