BMW 188mm LSD 4-Clutch 2-Way 75% / 75%
4 Clutch LSD for extreme performance. 2-Way 30 degree ramps on coast and drive give 75% lockup on coast and 75% on drive. These are suited to dedicated track cars running slicks, and drift applications. Not recommended for road rally, road, track days or club racing. You would really have to know what you are doing to know that you wanted this build. See the 2-way 45% / 45% build for most applications.
This is our rebuilt 4-clutch Race 188mm LSD unit (not whole diff) with new or near-new OEM clutches to fit most E28, E30, E32, E34 and E36, Z3. Fits the 6 cylinder models only, or a 4cyl model if it has the larger diff. This is the LSD centre of choice for circuit racing, blub racing and dedicated track cars. A very significant improvement in cornering speed and general performance. We also sell gear sets, clutch kits and LSD rebuild kits.
These LSDs are fully rebuilt, cleaned, inspected and oiled. Worn components have been replaced, steel surfaces machined where necessary, and clutches are replaced with brand new or near-new OEM parts as required. Old bearings have generally been removed.
Upgrades: The New Clutches upgrade is normally $678 (two sets) and includes four Hardcore Steel Plates and four new OEM clutch plates. The bolt upgrade is very highly recommended to avoid top cap breakage. The Chromoly-Vanadium Top Cap upgrade is an excellent choice for track cars and aggressive road cars where diff failure is not an option.
