BMW M Performance | OEM Limited Slip Differential

The BMW M Performance limited slip differential is a mechanical rear axle differential that replaces the original one with the aim of reducing wheel slip when one of the wheels has less grip. The limited slip differential ensures that the power is delivered to  the wheel with the most grip, ensuring better traction and handling than with a conventional differential This technology from the M models is now available for vehicles with the B58 engine with automatic transmission or vehicles with N55 or B58 with manual transmission

The M Performance limited slip differential optimizes traction and ensures even more controllable and precise driving behavior in all situations. A valuable addition to a sporty driving style or track driving. The clutch-type mechanical differential features a 30% lockup on acceleration and 9% lockup on deceleration. The differential works with the existing DSC system to provide excellent traction wet or dry.
