PRODUCT DESCRIPTION
RacingDiffs Performance Upgrade Kit for BMW M F/G Chassis: Conversion to Electronic-Mechanical Hybrid Limited Slip Differential
Transform the performance of your BMW M F/G chassis (M2, M3, M4, M5, and M6) with the innovative differential upgrade kit from RacingDiffs. Meticulously designed for advanced users and track enthusiasts, this kit not only solves the inherent limitations of BMW's first electronically controlled limited-slip differential system, but also offers unparalleled value for money and simple installation.
Key Benefits:
Instant Response: Eliminates the annoying lock delay experienced with the standard electronic system. Our solution increases your differential's reactivity, giving you power when you need it most.
Increased Durability: Overcome the wear problem that affects the original clutch pack after only 30,000 kilometers. With our enhanced clutch pack, your differential remains responsive and efficient for a long time.
Mechanical Preload: We introduce an exclusive preload washer that adds an impressive 80 Nm of mechanical preload. Forget about relying entirely on electronic actuators – you now have the mechanical backup you need.
Hybrid Advantage: Experience the robustness and responsiveness of a traditional limited-slip differential, combined with the sophistication of modern technology. The future of differential performance is here.
Cost-Effective Solution: Why spend a fortune on aftermarket limited-slip differentials? RacingDiffs offers top-tier performance at a fraction of the cost, ensuring superior quality without the hefty price tag.
Hassle-Free Installation: Forget about tedious tasks of rectifying the welded ring gear and drilling holes. With RacingDiffs, there are no complicated backlash adjustments. Install it easily and hit the road faster.
