MMX Performance G8X M2 / M3 / M4 Dual Differential Mount
4 IN STOCK
The MMX Performance G8X M2 / M3 / M4 Dual Differential Mount is a precision-engineered drivetrain upgrade designed to significantly improve differential stability, traction, and power delivery in BMW’s latest M platform. Developed specifically for the G87 M2, G80/G81 M3, and G82/G83 M4, this billet solution utilizes the factory secondary mounting location to add a critical second support point to the differential assembly.
Under high load conditions such as hard acceleration, aggressive cornering, and track use, the factory differential mounting system allows for unwanted movement. This can lead to inconsistent power delivery, reduced traction, and premature wear on drivetrain components. The MMX dual differential mount addresses this by increasing mounting rigidity, reducing deflection, and improving overall driveline response.
By stabilizing the differential more effectively, this upgrade enhances tire contact consistency, improves driver feedback, and reduces the likelihood of differential and CV seal weeping commonly associated with excessive movement. The result is a more controlled, predictable driving experience under both road and track conditions.
Manufactured from CNC-machined 6061-T6 billet aluminum, the MMX mount delivers exceptional strength while maintaining a lightweight profile. The design retains full compatibility with the factory differential sump and does not require fluid removal during installation. Fitment is fully OEM-based with no cutting, drilling, or permanent modification required.
The system is compatible with OEM rubber differential bushings (33 31 6 899 168) as well as aftermarket polyurethane or solid bush options, allowing flexibility based on the desired balance between comfort and performance. Installation is fully reversible, enabling the vehicle to be returned to stock configuration at any time.
