Description: The ZM4-HDG4 kit by ACT comprises their most popular Heavy Duty pressure plate matched with a 4-pad spring-centered race disc. ACT Heavy Duty pressure plates employ an exclusive diaphragm design to augment clamp load, diminish deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for exceptional performance. Precision cover stampings ensure rigidity and consistency.

The 4-pad spring-centered race disc features a spring-center to appropriately damp torsional vibrations for quieter operation and resist failure even under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. Engagement with the 4-pad spring-centered race disc is harsher, but shifting is faster. It's well-suited for smaller disc sizes in smaller engines.

Key Characteristics:

  • Feel: Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle.
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design.
  • Quality: Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance.

Recommended Use: Recommended for high horsepower street or race use, where quick, aggressive shifts are necessary.

ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability.

Vehicle Fitment: Compatible with various Mazda MX-5 Miata models from 2006 to 2015, including Grand Touring, Sport, Touring, GT, Special Edition, Club, and GS. All models equipped with the 2.0 L4 GAS FI 2000cc engine.

So cutie
Color: Cloud White, Material Type: Paper, PU
This is a bit large for a travel size jewelry box lol I really thought it was going to be a bit smaller than what it was. I can see why some of the ladies in the comments are saying they’re using it as their main jewelry box since they don’t have much jewelry for a standard sized jewelry box. With that being said, it’s cute and CAN be small enough for travel. It fits a lot and I got this one in particular bc I like that it has a bigger lower compartment for larger pieces. It’s a nice quality travel jewelry box. It’ll fit my needs. But if you have a knack for packing small and you value space. I’d say skip on this one or do due diligence to double check the measurements to see if it’s something you’re okay with packing.

CUTE
Color: Cloud White, Material Type: Paper, PU
I absolutely love this jewelry organizer! The 2-layer design gives it plenty of space without being bulky, making it perfect for travel. I was able to neatly store my earrings, necklaces, rings, and bracelets without anything getting tangled. The interior is soft and protects my jewelry really well, and the compartments are thoughtfully designed to keep everything in place. The compact size fits easily in my suitcase or handbag, which is a huge plus. The cloud white color looks elegant and makes it feel like a great gift option too. Overall, it’s practical, stylish, and very convenient for keeping jewelry organized on the go. Highly
