Description
Upgrade your manual G8X drivetrain with the Clutch Masters FX400 Factory Fit Twin Disc Clutch Kit, engineered specifically for the 2021–2023 BMW M3 and M4 equipped with the high-performance S58 3.0L engine. Designed to bridge the gap between OEM drivability and full race-ready performance, this twin disc clutch system delivers exceptional holding power while maintaining street-friendly manners.
Built as a direct factory replacement, the FX400 Twin Disc kit enhances the original twin disc design with upgraded materials, improved engineering, and increased durability. By eliminating the factory self-adjusting cover, increasing disc size from 8.5” to 9.5”, and reducing overall assembly weight by over 10 lbs, this system significantly improves torque capacity, responsiveness, and efficiency under high-performance conditions.
The FX400 8-puck ceramic configuration is ideal for enthusiasts running upgraded power levels who demand aggressive engagement and consistent performance under load. Despite its performance focus, the marcel cushion design helps minimize chatter, making it suitable for spirited street driving and occasional track use.
This complete kit includes everything needed for installation, featuring a lightweight aluminum flywheel, high-performance clutch discs, and all required hardware for a seamless upgrade. Whether you're pushing higher horsepower through tuning or replacing a worn factory clutch, the FX400 delivers the perfect balance of strength, reliability, and drivability.
