MFactory v2 Metal Plate LSD for BMW 3 Series E46 and 1 Series E8X 135i automatic
Supplier stock
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.

Which cars it fits
- BMW 3 Series E46 325i, 328i and 330i, 1998-2006

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.
