Action Clutch Stage 3 (1MS) Clutch Kit with Lightened Flywheel for 2018-2021 Subaru WRX (2.0L) - ACR-1818-FW

Fits 2018-2021 Subaru WRX Base, Limited, and Premium (2.0L).

Engineered for aggressive street use and occasional track duty, the Action Clutch Stage 3 (1MS) kit provides a significant 170% increase in holding capacity over the factory unit. This setup is built to handle low-to-mid horsepower builds where rapid engagement and high thermal resistance are required. The kit includes a lightened flywheel to reduce rotational mass, improving throttle response and allowing the FA20DIT engine to rev more freely.

The core of this kit is the Sprung MIBA Ceramic disc, which offers superior friction coefficients compared to organic materials. To ensure long-term reliability and protect your drivetrain, Action Clutch utilizes patented, fully enclosed spring retainers that prevent springs from popping out under high-stress conditions. While this ceramic kit introduces some clutch chatter, it is designed for maximum control and durability during drag, road racing, or drift sessions.
