If you’re looking for a clutch that can handle some serious driving without flinching, the ACT Xtreme Pressure Plate and Performance Street Sprung Kit (BM14-XTSS) is worth your attention. This kit is built for those who push their vehicles to the limits—think spirited drives, weekend track days, and everything in between. The standout feature here is the Xtreme pressure plate, designed with a unique diaphragm that ramps up the clamp load while keeping deflection to a minimum. What does that mean for you? Longer clutch life and a solid feel when you’re shifting gears.

ACT isn’t just throwing around fancy terms; they put their pressure plates through a rigorous four-stage heat treatment process. This ensures you get reliable performance, even when the heat is on. Plus, the precision cover stampings add a layer of rigidity that you can feel every time you hit the pedal.

Now, let’s talk about the clutch discs. The Performance street discs are a favorite among enthusiasts, and it’s easy to see why. They’re made from premium organic materials with a high copper content, which means better heat transfer and durability. The steel-backed lining gives you that extra burst strength when you really need it. With reduced marcel, these discs shift faster, making your driving experience that much smoother. You’ll appreciate the quiet operation without sacrificing strength and reliability.
