If you're looking to elevate your Mazda Miata's performance, the ACT ZM1-HDSS Advanced Clutch HD/Perf Street Sprung Kit might just be your new best friend. This kit combines the heavy-duty pressure plate that ACT is known for with their most popular street disc, making it a solid choice for both daily driving and spirited weekend jaunts. The heavy-duty pressure plate features a unique diaphragm design that not only boosts clamp load but also minimizes deflection, which means you get a longer-lasting clutch that can take a beating. Plus, each diaphragm goes through a four-stage heat-treating process, so you know it?s built to perform under pressure.

The pressure plate is all about precision too. With its carefully stamped cover, it offers the kind of rigidity and consistency that you'd expect from a high-performance component. Now, let?s talk about the Performance Street disc. It?s made from premium organic materials, packed with high copper content for better heat transfer, and features a steel-backed lining for added durability. This means you can shift faster with less worry about wear and tear, which is a big win on the track or the street.

Installation is straightforward, and if you need a little help, you can find the instructions here. Just keep in mind that you'll need to use your factory flywheel with this kit.

What can you expect from this kit? Well, the pedal effort is light to moderate, and engagement is smooth, which is perfect for those who want a responsive feel without the harshness. Thanks to ACT's diaphragm design, you can also expect longer friction life, which is a real bonus. And whether you?re cruising around town or hitting the track, this kit is engineered for both street and race use.
