If you're looking to take your Mazda RX-7 to the next level, the Advanced Clutch HD/Race Sprung 6 Pad Kit Z65-HDG6 is where it’s at. This isn't just another clutch kit; it's a game changer. ACT has packed this kit with their heavy-duty pressure plate, which is known for its unique diaphragm design. What does that mean for you? More clamp load, less deflection, and a longer-lasting clutch. Seriously, the four-stage heat-treating process on the diaphragms is no joke—it’s all about performance and durability.

Now, let’s talk about the heart of this kit: the 6-pad, spring-centered race disc. It’s designed to dampen torsional vibrations, which is crucial when you're pushing your ride to its limits. Sure, engagement might feel a bit harsher, but that's just part of the deal when you want faster shifting. Plus, this disc is perfect for larger clutch sizes, meaning it can handle more heat without breaking a sweat.

Installation is straightforward, and if you need a little guidance, you can check out the install instructions here. Just be aware that while the kit is designed for performance, it’s got a light to moderate pedal effort, so you won’t be killing your leg in traffic. You can expect some aggressive engagement, but that’s part of the fun, right?

On the technical side, this setup is engineered with precision. Everything from the ceramic friction materials to the dynamic computer balancing is done to ensure smooth high RPM reliability. It’s recommended for high horsepower street or race use, so you know it’s built to last. Just keep in mind, the flywheel requires a counterweight, which isn’t included, so plan accordingly.

Here are some specs to keep in mind:

• Clutch Disc Diameter: 9.4 in (240 mm)
• Torque Capacity: 420 ft/lbs
• Input Spline Quantity: 23
• Product Weight: 16.2 lbs

In short, if you’re serious about performance and want a clutch setup that can handle the heat—literally—this kit is a solid choice for your RX-7. It’s tough, reliable, and ready to rock. Just make sure you’ve got everything you need for installation, and you’ll be on your way to a more exhilarating drive.
