BMW M3 Clutch Kit - Clutch Masters - FX400 6-Puck Twin Disc with Aluminum Flywheel - `21-`23 is a factory-fit clutch assembly designed for 2021–2023 BMW M3/M4 (S58 3.0L). It combines the Clutch Masters FX400 6-puck twin-disc pack with a lightweight aluminum flywheel to increase torque capacity while reducing rotating mass.

This kit is aimed at enthusiasts who want a robust, track-capable upgrade without extensive drivetrain modification. The twin-disc layout spreads load and heat over more friction area, improving durability under repeated high-load use. The 6-puck design provides a more positive, performance-oriented engagement appropriate for spirited driving, drag or track use. The aluminum flywheel reduces inertia for quicker throttle response and easier rev-matching. Because this is a factory-fit assembly for the S58 application, installation is straightforward for experienced shops or our service centers.
