Drivetrain Mounts and Upgrades for BMW E21 320i M10 1.8L

Clear BMW chassis

Please ensure your correct model is selected

From the factory, engine and transmission mounts are rubber and thus a wear component. Worn out engine or transmission mounts create sloppiness and a disconnect between the driver and your BMW's powerplant. If your vehicle is purpose built for the track, we recommend solid engine and transmission mounts. These have zero deflection, but come at the expense of added NVH (noise, vibration, and harshness). Poly engine and transmission mounts offer a good balance between OEM rubber and solid mounts for those with mixed purpose vehicles, offering great performance and connection with little sacrifice in terms of NVH.

The Powerflex Rear Diff Mount Bushing for the BMW E21 offers a robust solution to support and stabilize the differential, replacing the standard rubber bushings with durable polyurethane. This upgrade minimizes unwanted differential movement, enhancing driving dynamics and responsiveness.

Key Benefits:

  1. Enhanced Stability: By minimizing differential movement, Powerflex bushings ensure consistent alignment, giving better rear-end stability.
  2. Improved Longevity: Unlike rubber, polyurethane is resistant to aging and degradation from elements like oil and road debris.
  3. Responsive Handling: With reduced play in the differential mount, power transfer becomes more direct, allowing for sharper throttle response.
  4. Vibration Dampening Options: Powerflex offers options like the Black Series for motorsport applications and the standard Purple for everyday performance with minimal increase in vibration.

These bushings are popular among E21 owners who want a durable, performance-oriented solution that balances comfort and handling precision. Ideal for both spirited driving and daily use.
