Construction & Design:
The clutch kit is meticulously engineered using premium materials and manufacturing processes. The Heavy Duty pressure plate features a unique diaphragm spring that undergoes a rigorous four-stage heat treatment, enhancing its strength and resistance to fatigue. This design increases clamp load while minimizing deflection, which contributes to longer clutch life and consistent engagement.
The 4-pad sprung race disc is crafted with select ceramic friction materials that tolerate high temperatures generated during aggressive driving. Its spring-centered design effectively dampens torsional vibrations, reducing noise and preventing premature failure. The wraparound spring windows and reinforced retainers provide additional support to the springs, ensuring durability under demanding conditions.
Performance & Sound
This clutch kit delivers a more aggressive engagement compared to stock setups, resulting in quicker and more precise shifts. While the engagement is harsher, it remains manageable with light to moderate pedal effort, making it suitable for both street and race environments. The spring-centered disc design helps reduce gear rattle commonly associated with performance clutches, providing a quieter operation without compromising performance.
