To fit E34 540i, E34 M5, E32 740i, 750i, 840i and 850i. Also E46 M3, E90/E92/E93 M3, E39 M5, E60 M5. All LSDs are custom builds or aftermarket. The base model custom 210mm LSD is a 1.5-way 25% / 40% unit with custom ramps
(ceramic ground, heat treated, blasted, relieved) which retain the
floating differential section. These have no free-play or noise, which
is common in almost every other custom unit. These are the most advanced
custom LSDs available anywhere in the world. The OEM type LSD may bave M12 or M14 bolt holes. Aftermarket solutions from
Diff Lab include MFactory, OS Giken and Cusco. I also stock 210mm rebuild kits, and 210mm gear sets. I
build complete differentials to order on an exchange basis.
