BMW 210mm LSD 4-clutch 2-Way 45% / 45% (E46 E60 E90 M3/M5)
These are fitted in-house only. You can order and attempt to have a unit shipped to your address, but it won't be shipped. These units will only be fitted to differentials supplied to Diff Lab for assembly. Ordering this product is a way of reserving one (these are very rare items) until your differential is sent in.
A 2-way 4-clutch 210mm LSDs for E36 M3, E46 M3, E60 M5, E90 M3 and early 5/6/7/8 series V8s and V12s. This is a 4-clutch unsprung unit with 45% lockup on drive and 45% lockup on coast. Only my custom LSDs are heat-treated, and feature relief cuts in the thrust plates to ensure long-life in the floating spider gears. Other LSDs are not heat treated and do not retain the floating spider gears. They will wear prematurely in both the splined gears and ramps. Other LSDs may also be noisy. Our thrust plates are ground to minimise reduction in the internal dimensions, thus retaining the original preload. DIff Lab only uses full size clutch plates, unlike our competitors.
Diff Lab custom LSDs are not noisy or clunky. Aftermarket LSD performance at a much more affordable price, and half the rebuild cost. These LSDs are much quieter than most aftermarket LSDs. These are no longer available with used clutches, original bolts, bearings still installed etc. The only 210 LSDs now on offer are fully optioned units.
There is only one configuration for these custom LSDs and that is:
- 2-way Ramps
- 45% lockup on drive, 45% lockup on coast
- New genuine full-size clutch plates (x4)
- New 12.9 Durlok cap bolts
- Resurfaced thrust plates
- Old bearings removed
- Thrust plate relief cuts
- Threaded cap
When fitting this LSD into the E46 M3, E60 M5 or E90 M3 you will also need E36 M3 3.2L output shafts. This is the correct LSD to fix the M Clunk in the M cars.
This is a 210mm LSD unit (not whole diff). Fits the models above only. Does not fit E39 V8 or later. 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. 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.
Would you risk purchasing an LSD that wasn't rebuilt with new OEM parts, and backed by a local warranty?
