For more information, visit www.P65warnings.ca.gov.Upgrade your BMW F2X or F3X with the MMX Billet Differential Inserts, engineered to limit movement in the factory differential mounts and enhance suspension geometry, especially during high-performance driving. This precision-machined kit effectively reduces the “slop” in the rear diff, improving handling and providing a more refined, connected driving experience.
Why Choose MMX Billet Differential Inserts?
These billet aluminum inserts fill the voids in the factory rear differential mounts, reducing deflection and keeping the suspension geometry optimal under load. The results are significant: improved rear-end stability, reduced understeer, and enhanced performance during launches and cornering. Installation is easy, taking less than an hour with no need to drop the subframe or differential, and is fully reversible. Built from high-quality CNC-machined 6061-T6 aluminum, these inserts ensure lasting durability without wear over time.
Enhanced Driving Precision without Additional NVH
Designed specifically for the BMW F2X & F3X chassis, the MMX inserts limit subframe movement while maintaining a smooth ride with no noticeable increase in noise, vibration, or harshness (NVH). Tested extensively in-house and by independent BMW enthusiasts, these inserts perform exceptionally well with both petrol and diesel, manual and automatic variants. If NVH is a concern, rest assured that our inserts are engineered to maintain factory-level comfort while maximizing performance gains.
