This construction reduces deflection and maximizes clutch life while providing a significant increase in clamping force over the factory unit. The pressure plate is built with precision cover stampings for consistent performance and rigidity.

The Performance Street disc features a premium organic friction material with high copper content for superior heat transfer and a steel-backed lining for high burst strength. The disc is designed with a reduced marcel for quicker shift response and a sprung hub to dampen driveline vibrations. This kit also includes the ACT Monoloc, a one-piece hardened chrome-moly steel wedge collar that replaces the standard two-piece ring in the pull-type clutch system for improved reliability and alignment.

Fits 1993-1995 Mazda RX-7 (Base, R1, R2, and Touring).

The ACT ZX6-XTR6 XT-M/Race Rigid 6-Pad Clutch Kit is engineered for high-performance applications and dedicated track use where rapid shifting and maximum clamp load are essential. At the core of this kit is the ACT Xtreme pressure plate, which utilizes an exclusive diaphragm design to significantly increase clamp load and reduce deflection. Every diaphragm undergoes a specialized four-stage heat-treating process to ensure consistent performance and durability through the most demanding driving cycles.

The 6-pad rigid race disc is constructed with high-grade ceramic friction materials and a heat-treated chrome-moly hub for maximum strength. The lightweight, rigid design facilitates faster gear changes and superior heat absorption compared to standard discs, though engagement will be noticeably harsher. To solve common pull-type clutch issues, this kit includes the ACT Monoloc—a one-piece, hardened chrome-moly steel upgrade that replaces the standard two-piece wedge collar and wire ring to prevent separation and ensure proper bearing alignment.
