BMW M4 Clutch Kit - Clutch Masters - FX400 6-Puck Twin Disc with Aluminum Flywheel - `21-`23: a direct-fit performance clutch assembly engineered for 2021–2023 M4 (S58 3.0L) applications. This factory-fit FX400 kit replaces the stock unit with a twin-disc design and lightweight aluminum flywheel for improved response under demanding driving.

The Clutch Masters FX400 6-puck twin disc is built to handle increased load during spirited street driving and occasional track use while maintaining a compact, factory-style fit. The twin-disc layout increases clamping surface area in the same space as the OE unit, helping deliver firmer engagement and better heat management without requiring major transmission modifications. The aluminum flywheel reduces rotating mass for crisper throttle response and quicker rev recovery. This kit is ideal for enthusiasts upgrading their drivability and consistency under higher loads.
