Why choose the BMW M Performance LSD
The BMW M Performance limited slip differential is a mechanical rear axle differential that limits wheel slip when one wheel loses traction, sending more torque to the wheel that can use it. The result is superior traction, more precise and predictable handling and a significant boost in driver confidence. Customers love the way this LSD makes the car feel planted and composed in borderline situations, with noticeable gains when accelerating out of tight corners. We have fitted and driven this differential ourselves and the improvement in real-world grip and balance is exactly what keen drivers want from an OEM BMW upgrade.
