ACT Mini Cooper S/JCW Heavy Duty Race Sprung 6 Pad Clutch Kit

The ACT Heavy Duty Race Sprung 6-Pad Clutch Kit (BM18-HDG6) is a high-performance drivetrain solution engineered specifically for the Mini Cooper S and JCW (F56 platforms). Designed for drivers who demand maximum heat tolerance and holding power, this kit features ACT’s signature Heavy Duty Pressure Plate. Utilizing an exclusive diaphragm design that undergoes a rigorous four-stage heat-treating process, this pressure plate significantly increases clamp load while reducing deflection to maximize clutch longevity under extreme stress.

The included 6-pad ceramic race disc is built for speed and durability. Its spring-centered design effectively damps torsional vibrations, protecting the transmission while resisting failure during aggressive high-RPM shifts. While the ceramic pads provide a much harsher engagement compared to organic street discs, they offer unparalleled performance in high-horsepower applications. This kit is the ideal choice for dedicated track cars or high-output street builds where rapid shifting and heat management are critical.

Key Features:

• Increased Clamp Load: Heavy Duty pressure plate provides a substantial increase in clamping force over stock for high-horsepower builds.
• 6-Pad Ceramic Friction Face: Utilizes select ceramic materials for elite heat tolerance and maximum frictional grip.
• Spring-Centered Race Disc: Engineered with wraparound spring windows and thicker retainer stampings to reduce stress and increase reliability.
• High RPM Reliability: 100% clamp load tested and dynamically computer-balanced for smooth operation at peak engine speeds.
• Aggressive Engagement: Optimized for fast shifting; provides a direct, mechanical connection required for competitive driving.
• Durable Diaphragm Design: Precision cover stampings and heat-treated diaphragms provide consistent pedal feel and rigidity.

Technical Specifications:

Driving Note: Due to the ceramic friction material and 6-pad design, expect some increased gear rattle (chatter) and a much shorter engagement window compared to the factory clutch. This kit is recommended for high-performance street or race use only.
