Genuine BMW M Performance LSD Differential Upgrade suit M135i F20 / M235i F22 N55 Auto & M140i / M240i Manual 6MT

The Genuine BMW M-Performance diff upgrade is perfect for drivers looking for added acceleration and grip in their F20 M135i / M140i & F22 M235i / M240i coupe.

Only M models receive a factory LSD (Limited-Slip Differential) which leaves other BMW and M Sport models with just electronic traction control to regulate wheel spin.

The F20/F22 is unleashed with totally new capabilities and driving performance when both wheels are maximising traction. A Limited-Slip Differential seamlessly and instantly transfers torque away from the spinning tyre and moves it to the opposite tyre. This means with the M Performance Diff 30% of torque is transferred to the other tyre.

The system works independently, and limits interference of traction control which will cut power or apply the brakes. The car feels faster because there is more traction and grip. As a Genuine BMW part, this M Performance differential is an easy and direct swap of your original diff and carries all of the same warranty and service requirements as any other BMW differential.

A performance LSD Differential upgrade for your M135i/M140i & M235i/M240i delivers performance far beyond the factory specification diff.

This M235i/M240i differential uses a 3.08 gear ratio, standard for M135iM235i with auto or manual transmission and used in M240i with manual transmission. Other RWD models can use this ratio to improve acceleration, however, AWD xDrive models must retain their stock factory axle ratios.

Full Kit Includes:

  • M Performance LSD Differential
  • Genuine BMW M Diff Oil
  • Lock Ring
