Clamp it down, send it forward. The MMX Dual Differential Mount for your G8X M3/M4 is purpose-built to solve the weak link BMW left behind—diff slop. From the factory, the rear differential hangs off a single bushing. It’s fine for daily driving, but the moment you floor it, that soft mount lets the diff twist, squandering torque, upsetting traction, and adding strain to the driveline. MMX fixes the flaw with a second solid mounting point that locks the diff into the subframe where it belongs. Precision CNC-machined brackets, premium hardware, and perfect alignment deliver OE-level fit with motorsport-level rigidity. The payoff? Faster throttle response, harder launches, and no more wheel-hop drama when boost hits. Why choose the MMX Dual Diff Mount? No flex, no waste – Keeps the diff planted under power and cornering. Maximum grip – Sends torque to the wheels instead of into rubber deflection. Built to last – CNC billet construction and hardware designed for punishment. Simple install – Bolt-on upgrade, no cutting, no compromises. For anyone chasing clean, repeatable power delivery from the S58, the MMX Dual Differential Mount is the bridge between factory comfort and uncompromised motorsport performance.

MMR's high-flow charge pipe kit includes everything needed to improve the performance, reliability, and aesthetics of your B48-powered BMW. Smooth bore pipework improves airflow over stock and due to reducing deformation of the hoses under load or vacuum, the MMR charge pipes also improve throttle response and power output. Increased boost pressure can cause the stock pipework to split or crack and cause drivability issues. MMR's charge pipes are made of lightweight aluminum which fit right in place of OEM charge pipes. Includes a 1/8” bung for easy addition of either methanol or water injection. Features: Two high-flow aluminum charge pipes with CNC leak-free connections Silicone coupler hose c-clip Jubilee clips x3 Throttle body bolts
