The MMX Performance Dual Differential Mount is engineered to reinforce one of the most critical components of the BMW G8X drivetrain. Designed specifically for the G87 M2, G80/G81 M3, and G82/G83 M4, this precision-machined mount utilizes the factory secondary bush mounting point to significantly improve differential stability under hard acceleration, spirited driving, and track conditions.
By adding a second support point, the mount increases rigidity, reduces unwanted differential movement, and sharpens driveline response. Installation is fully OEM-fit with no cutting, drilling, or fluid changes required. It bolts directly to the factory differential while retaining the factory sump, and is completely reversible so you can return the vehicle to stock at any time.
