Introducing the ACT ZM12-HDG6 Heavy Duty/Race Sprung 6 Pad Kit, designed for those who demand performance and reliability from their clutch system. This kit brings together ACT's renowned engineering and quality, making it a popular choice among automotive enthusiasts and racers alike. The ZM12-HDG6 features a heavy-duty pressure plate that utilizes an exclusive diaphragm design, which not only increases clamp load but also minimizes deflection, leading to a longer clutch life.
One of the standout features of this kit is its precision cover stampings, which enhance rigidity and consistency during operation. The diaphragm undergoes a meticulous four-stage heat-treating process, ensuring exceptional performance even under extreme conditions. Customers have noted, "The engagement is firm but smooth, and I can feel the difference in power transfer compared to my old setup."
The 6-pad, spring-centered race disc is engineered to dampen torsional vibrations effectively, which is crucial during high-stress driving situations. While the engagement may be a bit harsher, many users appreciate the quicker shifting response it provides. As one satisfied customer put it, "I love how responsive my shifts are now; it feels like I’m driving a completely different car!"
