Description
KMP BMW F8X Drexler Differential
The KMP Motorsport Bolt-On Differential is a high-performance solution developed for motorsport and endurance racing. This complete unit replaces the factory electronic GHAS differential with a robust Drexler Limited Slip Differential (LSD) and a KMP Motorsport final drive. Engineered for maximum strength, reliability, and performance, it’s the ideal choice for high-demand racing and track applications.
Mechanical LSD for Endurance Racing
Unlike the servo-operated Active M Differential, the KMP Motorsport Differential features a mechanical plated LSD, offering consistent, predictable performance. With reduced heat generation and enhanced durability, this unit is ideal for continuous, high-endurance racing.
- Racing-Specific Configuration: Ramp angles and preload are precisely tuned for motorsport use.
- Predictable Performance: Provides reliable and consistent grip in all racing conditions.
Optimised Final Drive Ratio (3.91)
The KMP Motorsport Differential utilises an optimised final drive ratio of i=3.91, compared to the stock 3.46 ratio, delivering 13% more wheel torque in all gears. This enhancement improves acceleration and wheel torque, giving drivers a competitive edge on the track.
Advantages Over BMW Motorsport Differentials:
- Replaceable final drive as a wear part for extended service life.
- Longer gear lifespan due to a motorsport-specific tooth profile.
- Serviceable components reduce long-term costs.
