XClutch 7.25in Triple Solid Ceramic Clutch Kit – 2004-2021 Subaru STI

Maximum Torque Capacity in a Single Assembly
The XClutch Triple Solid Ceramic clutch kit uses three solid ceramic friction discs for extreme torque capacity in a compact package. Designed for the highest-power competition applications where even the twin disc setup is not sufficient, the triple disc configuration handles torque levels well beyond what any twin or single disc design can manage. This is a purpose-built race clutch for serious motorsport use.

Why Triple Disc
Triple disc construction triples the friction surface area relative to a single disc, allowing very high torque capacity with manageable disc diameter. The solid ceramic discs provide excellent heat resistance for sustained race use and very low rotational inertia for quick throttle response. As with all solid ceramic multi-disc setups, engagement is abrupt and requires full, deliberate clutch releases — partial engagement will destroy the discs rapidly.

Why Choose XClutch
XClutch has been engineering performance clutch systems for over 30 years, with one of the most advanced clutch testing and R&D facilities in the world. Every kit is developed with in-house vehicle testing, and their full product range covers everything from street performance upgrades to dedicated race applications. For Subaru WRX, STI, and the GR Corolla/BRZ platform, XClutch’s depth of application-specific development is difficult to match at this price point.

The RallySport Take

The Triple Solid Ceramic is for high-power race builds where the twin disc is not enough. This is not a street clutch by any interpretation. If the power level demands it and the car is a dedicated competition vehicle, the triple ceramic delivers the capacity. Otherwise, the twin ceramic or twin sprung ceramic covers the majority of performance applications.
