This clutch kit is required if you are running the K to BMW ZF Flywheel.
- We recommend the 4-puck sprung disc with HD pressure plate for power goals up to 525whp.
4-pad spring-centered race disc made with high quality, ceramic friction materials. The engagement is harsher, but shifting is faster. The heavy duty torsional dampening springs are stronger, in most cases, than standard springs and are provided in the best sizes and spring rates to suit the application. The race disc features a heat-treated spring steel drive plate and is well-suited for the smaller disc sizes in smaller engines.
Feel: Aggressive engagement, quick shifts, OE to mild gear rattle;
Life: Premium ceramic friction materials provide moderate wear rates and high heat tolerance;
Quality: Utilizes wraparound spring windows, thicker retainer stampings and a heat-treated, spring steel drive plate to provide support, reduce stress concentrations and increase strength and reliability;
Recommended Use: Recommended for race use only;
ACT Difference: High burst strength and holds 28% more torque than typical organic materials;
Pressure plate features an exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All ACT diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's Heavy Duty pressure plates increase clamp load by 20 to 50 percent. The Heavy Duty pressure plates are recommended for use with a street or race disc.
Feel: Light to moderate pedal effort, positive engagement;
Life: Available disc life extended by ACT's exclusive diaphragm design;
Quality: Carefully engineered for improved durability, precisely assembled and accurately balanced;
Recommended Use: Recommended for street and race use;
ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability;
