The GKTech F8X M2/M3/M4 Eccentric Rear Knuckle Bearing - Kinematics kit is designed to correct the suspension geometry of the BMW F-series performance M models and is especially important when vehicles are fitted with lowered suspension.
Lowering a vehicle can offer significant performance benefits, but it also introduces challenges such as altered roll centres and altered bump steer curves. By utilizing 3D scanning and modelling, we've created solutions like the eccentric upright bearing to address these issues.
The Kinematics kit provides a number of benefits through it's design:
- Increase in negative camber for more aggressive alignment options
- Reduces the roll moment arm to be closer to OEM values, therefor reducing vehicle roll
- Adjustable bump steer and roll centre correction through eccentric design
- Spherical bearing to reduce bush deflection and ensure smooth range of operation through suspension travel
Our approach ensures that drivers can enjoy the advantages of a lowered centre of mass while maintaining the handling characteristics they expect from their vehicles. The bump steer adjustment options provide the flexibility needed to fine-tune performance and achieve a driving feel that is both familiar and predictable. Ultimately, our kinematics kit enhances the vehicle's performance while preserving its predictability and drivability.
- CNC Machined 6061-T6 Aluminium Body
- Common (COM10T) spherical bearing which is PTFE lined and self lubricating for increased longevity
Sold as A PAIR.
NOTE: Can ONLY be used with the Gktech adjustable toe arms seen HERE
