BMW Motorsport Limited Slip Differential (LSD) Upgrade: Performance Meets Precision
Upgrade your BMW E46 M3, E92 M3, E60 M5, E63 M6 or Z4M with a high-performance Motorsport Limited Slip Differential (LSD), engineered to outperform the factory M differential. Designed for high-power applications, this clutch-type LSD delivers stronger lock, improved traction and precise control for drift, track and aggressive driving.
Features
- Fully Forged Construction: All components, including the housing, are crafted from high-grade forged material for unmatched durability.
-
Adjustable Lock Settings: Choose 3 distinct ramp angle positions to match your driving style:
- 30/30 – aggressive 2-way, perfect for drifting.
- 30/60 – versatile 1.5-way, ideal for hill climb, rally, circuit, time attack, or newer drifters.
- 50/65 – smooth locking, great for street and track days.
- Optimized for Performance: Includes 4 Molybdenum-ceramics clutch plates with a lifetime warranty; delivers reliable performance without noise or vibrations when using quality LSD oil (e.g. Ravenol Racing 75W-140).
- Precision Fit: Designed for BMW Motorsport models for a seamless fit and optimal performance.
Performance Benefits
- Superior Traction: Dramatically improves grip for more exhilarating acceleration and corner exit.
- Enhanced Stability: Greater control and predictability—daily driving or maximum attack.
- Track-Ready Upgrade: Built to withstand continuous high-performance use where the factory viscous coupler falls short.
Transform your drive—don’t let factory limitations hold you back.
Technical Specs / Installation Tips
| Output flanges required (E92 M3, E60 M5, E63/E64 M6) | BMW PN 33131214068 |
| Output flanges required (E46 M3, Z4 M) | BMW PN 33131214087 |
| Backlash target | 0.08–0.12 mm (most BMW ring-and-pinion sets) |
- Adjustment shim set required: To finish the swap you’ll need the correct carrier-adjustment shims to set preload and backlash.
- What shims do: Let you dial-in factory backlash, center the ring gear for a correct contact pattern, and eliminate whine, premature wear, and heat build-up.
- TIP: We stock complete shim packs in 0.1 mm increments so you can fine-tune without hunting OEM spacers.
- Watch before you wrench: Our ~8-minute installation video walks through pressing bearings, measuring backlash with a dial indicator, selecting shims, and checking contact with marking compound.

Mandatory Oil Requirement
The use of SAE 75W-140 limited-slip differential oil + RedLine LSD friction modifier is mandatory. Using any other oil grade or oil not specifically formulated for clutch-type limited-slip differentials may cause improper operation, excessive noise, accelerated clutch wear or permanent damage. Damage or performance issues resulting from the use of incorrect oil are not covered by warranty.
