BMW E30 Dual Differential Mount Conversion Kit

Stop Rear Cover Cracking

Reinforce your BMW E30 like the pros. This Dual Differential Mounting Kit adds a secondary mount to distribute load across the rear cover—crucial for V8 swaps, turbo builds, sticky tires, and aggressive driving. Inspired by later BMW layouts and motorsport solutions, it’s a plug-and-play reliability upgrade for high-torque E30s.

Features

Dual-mount design: Adds a secondary attachment point to spread load and prevent rear cover ear cracking.
CNC aluminum & HD brackets: Precision-machined mount and spacer with powder-coated steel brackets and trunk plate.
Complete hardware: Includes two high-strength 10.9 extended casing bolts and all install fasteners.
Plug-and-play install: No welding; designed for medium-case (188 mm) E30 differentials.
Track-proven: Built for V8 swaps, turbo builds, drift, time-attack, and high-grip setups.

Performance Benefits

Prevents rear cover cracking and thread pull-out under shock loads.
Distributes torque into the chassis for improved durability and stability.
Protects drivetrain during launches, clutch kicks, and extended track sessions.
Confidence upgrade for high-power street and competition builds.
