To fit E30 and E36 318i and 318is. E21 and 2002 are listed when available. All LSDs are custom builds or aftermarket. Standard LSDs are only
available as part of a complete diff build. I don't sell standard
rebuilt LSDs on their own, only custom builds. The 168mm LSD is not too good without custom work. I increase the drive rate to 40% on all my 1.5-way 168mm units including the early E21/2002 units.
