ACT 2013-2015 Ford Focus ST HD Performance Street Rigid Clutch Kit

Part Details:

The FF2-HDSD clutch kit features ACT’s most popular Heavy Duty pressure plate paired with a Performance Street rigid-hub disc. This combination is designed to deliver increased torque capacity and durability while maintaining manageable street drivability for performance-oriented builds.

ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to increase clamp load while reducing deflection, helping maximize clutch life under higher torque conditions. Each diaphragm undergoes a four-stage heat-treating process to ensure strength, durability, and consistent performance.

Pressure Plate & Disc Design

Precision-stamped pressure plate covers provide added rigidity and consistency, allowing even clamp load distribution across the friction surface. This contributes to reliable engagement and reduced wear during spirited driving.

The ACT Performance Street rigid-hub disc is constructed using premium organic friction materials with high copper content for improved heat transfer. A steel-backed lining increases burst strength and durability, while the heat-treated chrome-moly hub provides additional strength for high-load use.

Street-Performance Engagement Characteristics

The rigid-hub design offers more direct power transfer and quicker shifts compared to spring-centered street discs, while still maintaining smoother engagement than ceramic race-style discs. This makes the clutch responsive without being excessively harsh.

Carefully selected rivet design and materials maximize disc strength while minimizing weight. As one of ACT’s lightest street disc options, the HDSD configuration supports faster shifts and responsive engagement with race-proven reliability and everyday manageability.
