As the OEM bushings wear, the OEM single-ear differential mount for the F8X chassis BMW tends to become unstable and become prone to pivoting under torque, causing an unsettled rear, clunking, and even fazilu
Although the OEM Diff Mounting Bracket for F8X BMW’s has a single mounting point, BMW included the provisions for a second mounting point from factory, making the Powerflex Dual Mount Differential Bracket a simple addition for dual-ear mounting.
This Powerflex Differential Mounting Bracket for F8X models comes with all bushings necessary for installation. Kit is ideal for cars that see both street and track-use, utilizing a slightly harder compound. This kit may be tolerable for street use, as it is not as rigid as solid aluminum or delrin, but will be much more harsh than OEM.
Benefits of Installation Include:
- Reduced drivetrain movement
- Improved throttle response
- A more controlled and consistent chassis response to acceleration / deceleration
- Improved tire-to-road power transfer due to reduced wheel hop
- Reduced strain on bushings
Kit includes Powerflex copper-based grease for installation. Re-lubing rarely required due to bushing construction/design.
