Introducing the MMR Differential Insert Kit, meticulously designed and engineered in-house in the UK for the BMW F2x and F3x chassis. This kit is your key to elevating your driving experience by limiting movement in the factory diff mounts, maintaining precise suspension geometry during cornering, and enhancing the responsiveness of your rear suspension and diff.
Installation is a breeze, taking under an hour, and completely reversible. Our billet aluminum inserts fill small voids in the four factory mounts and minimize vertical movement, eliminating slop for a refined and connected driving experience, especially during spirited drives. These durable inserts won't wear over time, ensuring a lasting performance improvement.
Concerned about noise? Our inserts are designed to transfer minimal to no NVH (noise, vibration, and harshness) into the cabin, providing a comfortable and enhanced driving experience. Should you experience higher-than-expected NVH, please double-check the installation for proper components alignment.
The BMW F2x and F3x series commonly experience vague and loose rear ends due to rubber diff mounts deflecting under load. Our precision-machined billet aluminum inserts fill these voids, limiting diff movement without compromising ride quality or introducing additional noise, vibration, or harshness into the cabin.
Tested extensively by MMR and independent BMW enthusiasts, these inserts are compatible with diesel, petrol, manual, and auto variants. Elevate your ride, improve suspension geometry, and experience a more connected drive with MMR's Differential Insert Kit. Order now for a driving experience tailored to enthusiasts like you.
