If you're looking to upgrade your clutch setup, the ACT HD/Perf Street Sprung Kit (HW4-HDSS) is a solid choice for those who want a mix of daily drivability and performance. This kit includes ACT's Heavy Duty pressure plate, which is a favorite among enthusiasts for good reason. It's designed with a unique diaphragm that cranks up the clamp load, cuts down on deflection, and helps your clutch last longer. Seriously, they put these diaphragms through a four-stage heat-treating process that really makes a difference in performance.

The pressure plate itself is built to last, with precision cover stampings that keep it rigid and consistent. Pair that with ACT's Performance Street disc, and you're in for a treat. The disc is made from premium organic materials with a high copper content, which means it handles heat like a champ. Plus, it has a steel-backed lining for added durability. You’ll notice faster shifts thanks to the reduced marcel, which works perfectly with the pressure plate for a snappy engagement.
