MMX Dual Differential Mount BMW G8x M2/M3/M4

MMX Dual Differential Mount – BMW G8x M2/M3/M4 Give your G8x driveline a stronger foundation. This MMX Dual Differential Mount adds a second support point to the rear differential by using the factory secondary bush mounting hole. The result is tighter control of the diff under hard acceleration and cornering, with a clear, OEM-like fit and finish. Why it matters The differential sends engine power to the rear wheels. Under load, the factory setup can allow the diff to twist slightly. That movement can soften throttle response, cause shunt, and stress seals. This mount braces the diff, cuts excess movement, and helps the car put power down more cleanly. What you will notice Sharper driveline response, more consistent launches, and improved traction when accelerating out of bends. It does not add power, but it helps you use the power you have more effectively. No diff oil drain is required for installation. Note: A small increase in driveline feel or noise (NVH) may be noticed, especially with polyurethane or solid bushes. Uses the factory secondary bush mounting hole to add support and stability under load OEM-style bolt-on fit – no cutting or drilling needed Keeps the factory diff cover in place – no fluid changes Works with OEM rubber bush (33 31 6 899 168), plus polyurethane or solid bushes Helps reduce diff and CV seal weeping by limiting movement CNC machined from 6061-T6 billet aluminium for strength and low weight Reversible – can be removed to return to stock Ideal for track days, spirited road driving, and tuned cars Fitment Designed for BMW G8x platform cars – M2, M3 and M4 with the S58 drivetrain.
