If you're looking to step up your clutch game, the Advanced Clutch Heavy Duty Pressure Plate MZ029 is worth checking out. This isn't just any pressure plate; it's built with a unique diaphragm design that ramps up the clamp load, cuts down on deflection, and really maximizes the life of your clutch. I've had my hands on this thing, and I can tell you, it’s been engineered for serious performance. Each diaphragm goes through a rigorous four-stage heat-treating process, which means you're getting something that can handle the heat—literally.

What I love about ACT's pressure plates is the attention to detail. The cover stampings are precision-made, giving you that added rigidity and consistency you want when you're pushing your ride to the limit. You can expect an increase in clamp load between 20 to 50 percent, which is a game-changer whether you're cruising the streets or tearing it up on the track.

Install Instructions:

Features:

  • Light to moderate pedal effort, which means you won’t be straining your leg every time you shift.
  • Thanks to that exclusive diaphragm design, you can expect a longer disc life, so you won't be swapping parts out every few months.
  • This plate is built for durability—it's carefully engineered, precisely assembled, and balanced to perfection.
  • Whether you're hitting the streets or the racetrack, it's ready for both.
  • Each unit is 100% clamp load tested and dynamically balanced for smooth operation at high RPMs, so you can push your limits without worrying about failure.

  • Diameter: 225 mm
  • Type: Heavy Duty

This pressure plate is a perfect fit for the 2016-2018 Mazda Miata, and trust me, if you’re serious about performance, you’ll want to give this a shot. It’s all about getting that perfect balance between daily drivability and track-ready performance, and the MZ029 nails it.
