CNC71 Rear Solid Aluminium Bushings Upgrade Kit BMW E46

This complete CNC71 solid aluminium bushing kit replaces the rubber mountings for the BMW E46 rear subframe and differential.

Rigid aluminium bushings eliminate movement caused by the factory rubber components, reducing drivetrain losses and suspension inertia because energy is no longer absorbed by bushing deflection. This provides a more immediate and consistent response under motorsport loads.

The bushings are anodised for corrosion protection.

Rigid mountings increase noise, vibration and harshness and may significantly reduce comfort in road use. Inspect the chassis mounting points and correctly align the drivetrain during installation.

This product is intended exclusively for motorsport and use on closed circuits. Professional installation is required.
