Diff Lab BMW 188mm LSD 4-clutch 1.5-Way 25% / 40% BMW 188mm LSD 4-clutch 1.5-Way 25% / 40%

A very rare factory 1.5-way unit. A 1.5-Way LSD with 65 degree ramps on coast and 55 degree ramps on drive. Four clutches are fitted. Up to four hardcore steels are fitted. These units have 2% lockup on coast and 40% lockup on drive. They offer the same smooth engagement and strong torque-holding ability of the custom 4-clutch unit, but with less lockup on coast for sharper turn-in.

This is a 188mm LSD unit (not whole diff) to fit most E28, E30, E32, E34 and E36 with brand new clutches fitted. Fits the 6 cylinder models only, or a 4cyl model if it has the larger 8-bolt/188mm diff, which is a direct swap. Guaranteed good physical and operational condition. Will change the whole car! A very significant improvement in cornering speed and general performance. A must-have for track-day cars, club racers and enthusiasts.

These LSDs are fully rebuilt, cleaned, inspected and oiled. Units have either new or near-new OEM clutches fitted. Check the "install new clutches" if you want guaranteed new clutches. Worn components have been replaced, steel surfaces machined where necessary. Old bearings have usually been removed. These are ready to be installed and backed by a warranty.

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.

Would you risk purchasing an LSD that wasn't rebuilt with new OEM parts, and backed by local support?
