BMW M2 F87 rear final drive upgrade - gear type torque-biasing LSD on built exchange axle - Part 30.309.160WKM234

Give your BMW M2 the grip it deserves with a gear-driven torque biasing limited slip differential supplied as a complete rear axle assembly on an exchange basis. This upgrade replaces the factory electronic locking unit with a robust mechanical solution that puts power to the tarmac, improves stability on corner exit and delivers confident performance on fast road and track. Precision built with OE-style tolerances, this is a bolt-in rear diff solution that feels OEM-plus and drives brilliantly in all conditions.

Supplied fully assembled for the F87 platform, the crown wheel is expertly machined to replace the welded OE gear, backlash is calibrated to factory spec and a blanking plate is included for the electronic actuator. No clutch plates to wear, no hassle. Just consistent traction, better acceleration and predictable handling from a premium gear type LSD.

We run these units on our own builds and customer cars. Feedback has been superb for everyday driving, spirited B-road use and circuit work. If you are searching for a BMW M2 differential upgrade that delivers real-world results, this is the one to choose.
