Diff Lab BMW 188mm LSD 4-Clutch 1.5-Way 45% / 75% Group A Replica BMW 188mm LSD 4-Clutch 1.5-Way 45% / 75% Group A Replica

My most most advanced unit, built using a late model M3 style capsule. This is an improved replica of the E30 M3 Group A LSD which features the same lockup configuration as the original, but with improved machining which provides smoother engagement and longer life. A 1.5-Way RLSD with 45 degree ramps on coast and 30 degree ramps on drive. Four clutches are fitted. Up to four hardcore steels are fitted. Coast lockup is 45% minimum. Drive lockup is special ordered from 45% to 75% at your request.

This late model 188mm LSD unit (not whole diff) fits E28, E30, E32, E34 and E36, Z3 and others of that era. Fits the 6 cylinder models only, or a 4cyl model if it has the larger diff. This LSD centre features 4 very large oil passages. These increase oil flow to the clutches dramatically. The unit is also much lighter than the earlier LSD. This is the LSD centre of choice for circuit racing where high differential temps can be a concern. A very significant improvement in cornering speed and general performance. A must-have for track-day cars, club racers and enthusiasts. 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. Check the "install new clutches" if you want guaranteed new clutches. 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.
