SPL BMW E9X/E8X Rear Lower Control Arm Knuckle Bushing
Part Number: SPL RLCB E9X
Unlock sharper handling, rock solid alignment and repeatable rear suspension performance on your BMW with the SPL Parts rear lower control arm knuckle bushing upgrade. This motorsport-grade spherical conversion replaces the soft factory rubber bushing at the knuckle end of the rear lower control arm, delivering precise toe and camber control under cornering, braking and acceleration. Perfect for fast road, track day, time attack and drift use, while remaining composed for daily driving.
- Replaces OEM rubber with a low friction Teflon-lined spherical bearing for maximum precision
- Minimises deflection under heavy load for consistent toe and camber
- Reduces bind through suspension travel for improved compliance and grip
- Largest possible FK bearing used in this location for longevity and low NVH
- Noticeably tighter rear end response, traction and stability
