If you're looking to take your Mazda RX-8 to the next level, the Advanced Clutch HD/Race Sprung 6 Pad Kit ZM8-HDG6 is a solid choice. This kit is built around ACT's Heavy Duty pressure plate, which is known for its robust design. The unique diaphragm setup not only ramps up the clamp load but also keeps deflection in check, ensuring that your clutch lasts longer even under some serious driving conditions. Each diaphragm goes through a four-stage heat treatment process, which really boosts performance and reliability.

The pressure plate itself is no slouch either. With precision cover stampings, it provides the rigidity you need for consistent performance. Now, let’s talk about the 6-pad, spring-centered race disc. This feature is a game changer. It dampens torsional vibrations, which is crucial when you're pushing your car to its limits. Sure, engagement is a bit harsher, but that’s what you want if you’re after faster shifting. Plus, the design is geared for larger clutch sizes, so it can handle more heat without breaking a sweat.

Installation is straightforward, but if you need a hand, ACT provides detailed instructions. You can check them out here.
