So, you’ve got a serious need for speed and a taste for performance, huh? Let me tell you about the ACT XT/Perf Street Sprung Kit, specifically the TC1-XTSS model. This isn’t just any clutch kit; it’s built for drivers who really push their machines to the limit. The Xtreme pressure plate is the star of the show here. It uses a unique diaphragm design that cranks up the clamp load, minimizes deflection, and ultimately extends the lifespan of your clutch. Seriously, this thing can take a beating.

What’s cool is that every diaphragm goes through a four-stage heat-treating process. This isn’t some half-baked assembly line job; it’s crafted for peak performance. You’ll also notice the precision cover stampings on the pressure plates, which add a level of rigidity and consistency that you can feel when you’re hitting those high RPMs.

Now, let’s talk about the performance street discs. These are the go-to choice for a lot of folks, and for good reason. They’re made from premium organic materials with a high copper content, which means they transfer heat like a champ. Plus, they’ve got steel-backed linings for that extra burst strength and durability you need when you're really pushing it. The reduced marcel in these discs allows for quicker shifts, making your driving experience smoother and more responsive.

Installation is straightforward, but if you need a hand, you can find the installation instructions here.
