Alright, car enthusiasts, let?s talk about the ACT HD/Perf Street Sprung Kit SC1-HDSS. If you?re looking for something that?s built tough yet still street-friendly, this is where it?s at. This kit features ACT?s Heavy Duty pressure plate, which is pretty much their bread and butter for a reason. It?s designed with a unique diaphragm that ramps up the clamp load without compromising on feel. That means you get a solid bite without the annoying deflection you might find in lesser kits. Plus, every diaphragm goes through a four-stage heat treatment process, so you know it?s gonna hold up under pressure.
The pressure plate is built to last, with precise cover stampings that keep everything nice and rigid. Now, let?s get to the Performance Street disc. This thing is made from high-quality organic materials, loaded with copper for better heat transfer. The steel-backed lining gives it some serious burst strength, so you can push your limits without worrying about it falling apart. And with reduced marcel, shifting is quicker and smoother, making it a perfect match for the pressure plate.
