MFactory Metal Plate LSD for Honda Civic and CR-X with D15 / D16, 40 mm version, also for the ZC engine, black speedo gear
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
- Honda Civic and CR-X with D15 or D16 engines
What to check
- 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 front-wheel drive, 1.0 way for the road, 1.0 or 1.5 way for circuit and time attack.
