If you're serious about pushing your Nissan 300ZX to its limits, the Advanced Clutch XT/Race Rigid 4 Pad Kit NX6-XTR4 is a game changer. This kit is built for those who demand top-notch performance from their ride. The heart of this setup is the Xtreme pressure plate, designed specifically for drivers who don't hold back. It uses a unique diaphragm design that amps up the clamp load, cuts down on deflection, and ultimately extends the life of your clutch. Trust me, this isn't just marketing fluff; ACT has put in the work with a four-stage heat-treating process that gives you performance you can count on.

The pressure plates are no joke either. They’re crafted with precision cover stampings, which means you get that much-needed rigidity and consistency when you're tearing up the track. Now, let’s talk about the 4-pad rigid race discs. They’re made from high-quality ceramic friction materials, which means they can handle the heat and then some. The chrome-moly hub? It’s heat-treated for added strength and durability, so you know it’ll stand up to some serious action.

One of the standout features of this kit is how lightweight and rigid the design is. This translates to quicker shifts, which is a blessing when you’re in the heat of competition. Sure, engagement might feel a bit harsher compared to your stock setup, but that’s just part of the game when you’re looking for speed. Plus, the 4-pad disc is especially suited for those smaller engine setups, making it a perfect fit for your Z.

Installation is straightforward if you know your way around a garage. If you need a little guidance, you can check out the install instructions here.
