MFactory v2 Metal Plate LSD for BMW Z4 2.2i, 2.5i, 3.0i

The MFactory metal plate LSD locks the driven wheels through packs of friction plates, pressed by ramps and preload springs. Unlike a helical unit, it keeps locking when one wheel loses grip, which is why it is made for dedicated circuit, rally and drift cars.

What to check

  • The v2 version uses Active Friction Type-SS plates: noise and vibration in slow turns drop by up to 50%.
  • 1.0 way locks on acceleration only. 1.5 way locks on acceleration and partly under engine braking. 2.0 way locks equally on and off throttle.
  • The 1.0/1.5 version ships set to 1.5 way and the 1.5/2.0 version ships set to 2.0 way, both with plates stacked for 100% lock. Switching ramps requires opening the differential.
  • Preload, ramp angle and lock percentage are adjustable without special tools, with the gearbox removed.
  • The plates wear: MFactory asks for their thickness to be checked at every service, minimum 1.58 mm. Replacement plates and preload springs are sold separately.
  • MFactory recommends: on rear-wheel drive, 1.0 or 1.5 way for road and circuit, 2.0 way for drifting.
