BMW 188mm Limited Slip Differential (LSD) Unit — Unlock Superior Performance
Upgrade your BMW E30, E36, E34 or Z3 with a high-performance 188mm Limited Slip Differential (LSD), designed for 6-cylinder models and drivers who demand real traction. Whether you're drifting, building a track car or improving street performance, this clutch-type LSD delivers consistent lock, better stability and eliminates one-wheel spin under load.
Forged to Last: Fully forged internals and housing provide extraordinary strength and longevity—reliability when you need it most.
Adaptable Performance: Three ramp-angle settings let you tailor behavior to your driving style:
- 30/30 — aggressive 2-way for high-intensity drifting.
- 30/60 — versatile 1.5-way for a wide range of motorsports.
- 50/65 — smoother lock for daily comfort + track-day fun.
Innovative Clutch Pack (Lifetime Warranty): Equipped with six Molybdenum-ceramics clutch plates for sustained peak performance in any conditions—covered by our lifetime warranty.
Quiet, Composed Operation: With optimal preload and quality LSD oil (e.g., Ravenol Racing 75W-140), the unit runs without unwanted noise or vibration.
