Introducing the ACT HC12-HDG4 Heavy Duty/Race Sprung 4 Pad Kit, a top choice for performance enthusiasts looking to elevate their driving experience. This kit is designed with precision and durability in mind, featuring ACT's highly regarded Heavy Duty pressure plate. Thanks to its unique diaphragm design, the pressure plate increases clamp load while minimizing deflection, which ultimately extends the life of your clutch.

Customers have noted the noticeable difference in performance after installation. One user mentioned, "The engagement is definitely more aggressive, but it makes shifting feel incredibly precise. It?s a game changer for my track days!" This feedback highlights the kit's ability to deliver a more responsive driving experience, especially under demanding conditions.

The HC12-HDG4 kit includes a 4-pad spring-centered race disc, engineered to dampen torsional vibrations for quieter operation. This feature is particularly beneficial for those who drive in varied conditions, as it helps maintain a comfortable ride while still providing the performance needed for spirited driving. Another customer shared, "I was impressed with how well it held up during my last race. No issues with slippage, even under high torque!"
