ACT XT/Race Sprung 4 Pad Kit Nissan 300ZX 1990-1999 - NX6-XTG4

If you're looking to take your Nissan 300ZX to the next level, the ACT XT/Race Sprung 4 Pad Kit (NX6-XTG4) is a solid choice. This kit is built for those who really push their cars, whether you're tearing up the streets or hitting the track. The Xtreme pressure plate is designed specifically for drivers who demand a lot from their clutch system. It's got this unique diaphragm design that cranks up the clamp load, which means less deflection and a longer-lasting clutch. Trust me, after going through the four-stage heat-treating process, this thing is ready for anything you throw at it.

Now, let’s talk about the 4-pad spring-centered race disc. It’s not just for show; it’s engineered to dampen those torsional vibrations, so you get a quieter ride without sacrificing performance. Sure, the engagement is a bit harsher, but that just means quicker shifts when you need them most. Plus, the spring retainers are built tough, with wraparound spring windows and thicker stampings to handle the stress. You can feel the reliability when you’re pushing your car hard, and that’s a huge plus.

When it comes to installation, you’ll want to check out the instructions here. It’s straightforward, but having a guide always helps, right?

Here’s what you can expect from this kit:

  • Moderate to heavy pedal effort with aggressive engagement—perfect for spirited driving.
  • Decent friction life, thanks to that clever diaphragm design ACT has going on.
  • Engineered with precision and balanced for smooth operation at high RPMs.
  • Great for high horsepower setups, whether on the street or the track.
  • Each component is clamp load tested and dynamically balanced, so you know it’s reliable.

Some key specs to keep in mind:

  • Clutch Disc Diameter: 9.4 inches (240 mm)
  • Disc Material: Ceramic, which means it can handle the heat.
  • Input Spline Quantity: 24, so it fits just right.
  • Torque Capacity: 630 ft/lbs, which is a solid step up from the OE.
  • Weight: 18.6 lbs, making it a manageable addition to your setup.

This kit fits the Nissan 300ZX from 1990 to 1999, so if you’re looking to boost your ride’s performance, the ACT XT/Race Sprung 4 Pad Kit is definitely worth considering. It’s built for those who aren’t afraid to push their limits, and trust me, you’ll feel the difference.
