If you're looking to step up your game with your Mazda RX-7, the Advanced Clutch HD/Race Rigid 6 Pad Kit ZX2-HDR6 is a solid choice that really delivers. I've had the chance to put this kit through its paces, and let me tell you, it's a game changer. It features ACT's renowned Heavy Duty pressure plate, which is built to handle the heat and stress of serious driving. The unique diaphragm design not only boosts clamp load but also cuts down on deflection, which means your clutch lasts longer and performs better. It's been heat-treated through a four-stage process, so you know it's tough as nails.The 6-pad rigid race discs are where this kit really shines. Made with high-quality ceramic friction materials, they offer a lightweight feel that allows for quicker shifts. Now, I won’t sugarcoat it—engagement can be a bit harsher, but if you're after speed, that's what you want. Plus, the chrome-moly hub is heat-treated for added durability, giving you confidence that it can take a beating without breaking a sweat.Installation is straightforward, and if you need a hand, you can find the instructions here. Just be aware that this kit is designed with racing in mind, so it’s not for the faint-hearted. The pedal effort is light to moderate, but you’ll definitely notice the aggressive engagement, which can lead to some increased gear rattle. As for the specs, this thing is built for performance. It has an 8.8-inch clutch disc diameter (224 mm), and with a torque capacity of 345 ft/lbs, it’s ready to handle whatever you throw at it. Just keep in mind that while the friction life is moderate, it’s extended thanks to ACT's exclusive diaphragm design. That said, the rigid nature of the setup might lead to a bit more spline wear, so just something to keep in mind.Overall, if you're serious about racing and want a clutch that can keep up with your ambitions, the ZX2-HDR6 kit is worth considering. Just remember, it’s all about the balance between performance and durability, and this kit nails it.
