BMW E30 E21 E12 Engine Mounts Polyurethane

The BMW E30 E21 E12 M20 Engine Mounts are upgraded steel and polyurethane engine mounts designed for BMW vehicles equipped with the M20 engine.

Manufactured using 4 mm steel and 80 Shore A (80ShA) polyurethane, these reinforced engine mounts provide a firmer alternative to ageing factory rubber mounts, helping reduce excessive engine movement under acceleration, braking and changing drivetrain loads.

During demanding driving conditions, engine torque can cause the engine to move within its mounting points. Excessive movement can place additional stress on surrounding drivetrain components, particularly when engine power and torque have been increased.

The upgraded polyurethane bushings help control engine movement and maintain more consistent engine positioning, making these mounts suitable for drifting, track driving and performance-oriented BMW builds.

They are also a practical replacement for worn original engine mounts on compatible BMW E30, E21 and E12 vehicles equipped with M20 engines.

Key Features:

- 80ShA Polyurethane Bushings – Firmer than typical original rubber mounts to help control engine movement.

- 4 mm Steel Construction – Reinforced steel mounting components.

- Reduced Engine Movement – Helps limit excessive engine displacement under acceleration and drivetrain loads.

- Improved Drivetrain Response – Reduced mount deflection can provide a more direct drivetrain feel.

- Suitable for Increased Engine Torque – Designed for performance applications where engine movement needs to be controlled.

- Replacement for Worn Factory Mounts – An upgraded alternative to ageing original rubber engine mounts.

- BMW M20 Engine Compatibility – Designed for compatible M20-powered BMW E30, E21 and E12 vehicles.

- Motorsport Applications – Suitable for drifting, track driving and performance builds.

Vehicle Compatibility:

Designed for BMW vehicles equipped with the M20 six-cylinder petrol engine:

- BMW E30 – M20 engine

- BMW E21 – M20 engine

- BMW E12 – M20 engine

Important: Compatibility is based on the M20 engine and the corresponding engine mounting configuration. Verify the engine brackets, subframe and mounting arrangement before ordering, particularly on engine-swapped or modified vehicles.

Installation Information:

These mounts are designed to replace the original engine mounting components on compatible BMW M20 installations.

Before installation, inspect the engine mounting brackets, subframe mounting points and surrounding components for cracks, corrosion or damage.

Ensure the engine is correctly supported during removal and replacement of the original mounts.

After installation, check engine alignment and clearance around the exhaust, steering components, cooling system, transmission and surrounding bodywork.

Important: Polyurethane engine mounts are firmer than standard rubber mounts and may transmit additional noise, vibration and harshness (NVH) into the vehicle interior.

Professional installation is recommended, particularly on modified or motorsport vehicles.
