The ACT Heavy Duty / Race Rigid 4-Pad Clutch Kit for the 2002-2005 Subaru WRX EJ20 platform is designed around this generation’s smaller disc diameter and EJ20 engine characteristics.

Why Choose ACT

Advanced Clutch Technology has been manufacturing performance clutch systems in the United States since 1993. Every ACT pressure plate uses a proprietary diaphragm design that increases clamp load and reduces deflection compared to OEM units, and every diaphragm goes through a four-stage heat-treating process before it leaves the factory. The result is a clutch system that holds more power than the stock unit, engages more precisely, and lasts longer under the kind of driving that wears factory clutches out quickly. ACT designs each application from scratch rather than modifying OEM tooling, which means the fitment is precise and the performance is intentional. Whether the build is a street-driven daily driver or a dedicated track car, ACT offers a kit at the correct specification for the use.

The RallySport Take

The ACT Heavy Duty 4-pad Rigid kit is for builds where daily drivability has already been traded for performance. Engagement is abrupt — there is no organic cushion and no spring damping in the hub. What you get is the fastest possible clutch engagement, ceramic friction material that does not fade under sustained track heat, and a chrome-moly hub that handles repeated aggressive launches without fatigue. This is not a commuter clutch. It is the correct choice for time attack, track days, and competition builds where every second and every shift matters. Fits Saab, Subaru applications 1991-2009.
