ACT 06-25 Subaru WRX XT/Race Rigid 6 Pad Clutch Kit

ACT Xtreme Race Rigid 6-Pad Clutch Kit for Subaru WRX and EJ-Series Models

The ACT Xtreme Race Rigid 6-Pad Clutch Kit for the 2006-2026 Subaru WRX and EJ-series models combines the Xtreme pressure plate’s maximum clamp load with a 6-pad rigid ceramic race disc, ACT’s most aggressive single-disc configuration. This kit is built for high-power EJ-series builds where clutch slip is not acceptable and engagement speed is the priority. Expect abrupt engagement and faster shifts. Not a daily driver setup.

DETAILS

• Pressure plate: ACT Xtreme, maximum clamp load
• Clutch disc: 6-pad rigid ceramic race
• Disc material: high-quality ceramic friction
• Hub: chrome-moly, heat-treated, rigid (no dampening)
• Marcel: none, immediate full engagement
• Clamp load: maximum in ACT single-disc lineup
• Use case: high-power builds, track and competition
• Note: harsh engagement, not suitable for street daily use

The 6-pad rigid race disc uses ceramic friction material bonded to six individual pads rather than a full friction face. The reduced contact area runs cooler and resists fade at sustained high temperatures, critical on large-displacement or high-boost EJ builds where clutch heat is a genuine concern. The rigid construction (no spring dampening in the hub) means there is no compliance in the driveline at the clutch, the engine connects directly to the transmission.

The chrome-moly hub is heat-treated for strength. The lightweight, rigid design allows quicker clutch engagement and faster shifts than any sprung disc alternative. The 6-pad configuration is recommended for larger disc sizes in higher-torque applications, on the EJ-series WRX and STI, it is the correct choice when the power level justifies the engagement harshness. Paired with the Xtreme pressure plate, this kit will not slip regardless of how much power the engine is making.

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 Xtreme 6-Pad Rigid is for competition-focused EJ builds, time attack cars, hillclimb cars, builds that see more track time than street time. The engagement is aggressive and the driveline feel is abrupt. If you are looking for a clutch that holds any power level the EJ can produce in a single-disc package, this is it. Fits the 2006-2026 Subaru WRX and the EJ-series Subaru applications in the fitment table.
