ACT HD/Race Rigid 4 Pad Clutch Kit – 2006-2026 Subaru WRX

ACT Heavy Duty Race Rigid 4-Pad Clutch Kit for Subaru WRX and EJ-Series Models

The ACT Heavy Duty Race Rigid 4-Pad Clutch Kit for the 2006-2026 Subaru WRX and EJ-series models uses the Heavy Duty pressure plate with a 4-pad rigid ceramic race disc. The 4-pad configuration suits smaller disc diameters and lighter-weight builds where the 6-pad’s extra pads are not required.

DETAILS

• Pressure plate: ACT Heavy Duty
• Clutch disc: 4-pad rigid ceramic race
• Hub: chrome-moly, heat-treated, rigid
• Marcel: none
• Clamp load: Heavy Duty level
• Use case: track builds, 4-pad suited for smaller disc sizes
• Engagement: abrupt rigid

The 4-pad rigid disc uses ceramic friction material on four individual pads with a rigid chrome-moly hub. The lighter construction compared to the 6-pad suits applications where disc diameter is smaller and total friction pad area is less critical. Immediate engagement, no compliance.

The Heavy Duty pressure plate provides appropriate clamp load for moderate-to-high power EJ-series builds without the pedal weight of the Xtreme plate. Together with the 4-pad rigid disc this is a focused track configuration at a more approachable clamp load level.

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 Subaru applications 2005,2007-2025.
