Have a 210mm differential and need the ultimate LSD performance upgrade? You found the right place. With gobs of dynamic lockup and and twice the friction surface of a stock unit, you will be able to extract more rear wheel traction than ever before.

The best part? Stock drivability is maintained by properly tolerancing the components to avoid preload! No dragging the inside wheel during slow maneuvering and increased lockup under acceleration.

With this purchase, you'll receive four special tolerance 210mm clutch discs, four special tolerance 210mm 4-lug dog ear plates and eight 12.9 grade carrier bolts. Everything that you need to build the baddest differential on the block!

This kit does not require any machine work. It is a drop in design.

Our clutches are coated with a molybdenum traction surface and are specifically designed for the high temperature abuse situations that occur within the BMW differential. The clutches will retain the smooth limited slip engagement feel of the stock differential while providing long term durability. Our dog ear plates are precisely machined and hardened to ensure long term use.

This kit will not work with the stock E46 M3 LSD unit. If you have this unit, it is highly recommended to replace it with a standard style 210mm unit. Please contact us for additional details.
