If you're looking to upgrade your Mazda Miata's clutch game, the Advanced Clutch Xtreme Pressure Plate MZ014X is worth your attention. This isn't just any pressure plate; it's built with a unique diaphragm design that really cranks up the clamp load. What does that mean for you? Well, you get a solid boost in performance, less flex, and a longer-lasting clutch life. Seriously, this thing is designed to handle the heat—each diaphragm goes through a four-stage heat-treating process that ensures it can take whatever you throw at it.
Now, let’s talk about the feel. When you step on the pedal, you’ll notice a moderate to heavy effort, but that just means you get positive engagement every time. You won't be left second-guessing whether you’re in gear. Plus, ACT has nailed the precision in their cover stampings, which means you’re getting a pressure plate that’s as rigid as it is consistent. They claim an increase in clamp load by anywhere from 50 to 120 percent, and I can tell you from experience, that’s a game-changer whether you’re cruising the streets or hitting the track.
Installation is straightforward, but if you need a little guidance, you can check out the installation instructions here. It’s always nice to have a reference handy, especially if you’re tackling this in your garage.
In terms of specs, this pressure plate measures in at a diameter of 7.9 inches (200 mm) and weighs about 8.2 lbs. It's classified as a performance-grade component, and it’s 100% clamp load tested and dynamically computer balanced. That means it’s not just built for performance; it’s built for reliability at high RPMs too. And just to give you peace of mind, it’s got an SFI rating of 1.1, which is a nice touch for those who care about safety and compliance.
So, if you’re rocking a Mazda Miata from 1990 to 1997, this MZ014X ACT Xtreme Pressure Plate is a solid investment. You’ll feel the difference in how your car responds, and you can trust that it’s going to hold up under pressure—whether you’re on the street or at the track.
