Through the smooth and constant distribution of power to the wheels, the MFactory Metal Plate LSD puts the power-to-the-ground and maximises your vehicle's traction where conventional Torsen LSD's succumb to their limits. The Metal Plate LSD is by far the best performing Limited Slip Differential available for a dedicated Circuit, Rally or Drift car

Diamond Cut to exacting tolerances from Forged High-Nickel-Chromium-Molybdenum Steel
Perfect fitment & finish ensures hassle-free installation & maintenance, each and every time

Designed using leading-edge Solidworks 3D CAD & Cosmos FEA software
Advanced Gear Geometry minimizes parasitic drivetrain losses. Race transmissions built with MFactory components transfer, on average, 1-2% more power to the ground over our competitors!

Stress Tested on loaded dynos
Ensures our differentials are strong enough to handle the shock loads encountered during racing, yet also durable enough to handle the variable loads encountered during day-to-day driving

Fully Adjustable at-the-track
Users can fully adjust the LSD settings, be it initial pre-load or lock percentage at-the-track without any special tools necessary (disassembly of transmission required)

Coil Spring Pre-Load System (Application Dependant)
Through the integration of a coil spring pre-load system, gone are the days of on/off jerkiness, ensuring smooth power transition and maximum throttle response

3rd Generation Design (Application Dependant)
Through the accumulation of over 15 years of ongoing research and statistical analysis, we are proud to introduce our new v3 Metal Plate LSD applications for BMW and Honda. A commonly known weakpoint with Plate type LSD's are the ears on the Plates. When subjected to high loads, they can regularly break off from the main plate surface. With the new MFactory v3 Metal Plate LSD, which uses our 2nd Generation Active Friction Plates (originally developed for our competition Touring Cars), the surface area of each ear is increased substantially, significantly increasing durability. In addition, our Cold-Forged Spider Gears are now subjected to an advanced ceramic surface coating, significantly decreasing surface friction and increasing surface hardness by 30%!

In partnership with OZ Performance Drivetrain of Australia, we are proud to introduce our new v3 Metal Plate LSD - OZ Series applications for BMW and Honda. A commonly known issue with Plate type LSD's is the associated NVH (noise, vibration, harshness) during low speed manoeuvres, especially noticeable on a daily driver. With the new MFactory v3 Metal Plate LSD - OZ Series, our Active Friction Plates incorporate specially designed oil channels and a proprietary 3-Stage Nano-Peen process, helping to reduce NVH by as much as 50%

Low-Cost Maintenance Parts
Unlike with our Helical LSD, the Metal Plate LSD will require regular maintenance to keep performance at its peak. Replacement pre-load springs & plates are always in stock and offered at an affordable price

Fitment Notes

Honda B16A2 Fitments: Will not directly fit models previously equipped with an OEM Viscous LSD, and will require a Ring Gear change

BMW 135i MT/335i 07+ MT/DCT/335d Fitments: Will not directly fit these models due to the oem Ring Gear being welded onto the differential. The Ring Gear will either need to be machined to accept the new LSD, or a new bolted Ring & Pinion used. MFactory Competition Products is one of only 3 companies in the US that can provide this service that meets oem tolerances, and the only US company to manufacture precision aftermarket performance Ring & Pinions (Final Drive Gears) for the BMW
