Description: The ZM5-HDG6 kit by ACT features their most popular Heavy Duty pressure plate paired with a 6-pad, spring-centered race disc. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to enhance clamp load, diminish deflection, and optimize clutch life. Each diaphragm undergoes a four-stage heat-treating process for exceptional performance. Precision cover stampings ensure rigidity and consistency.

ACT's 6-pad, spring-centered race disc incorporates a spring-center to effectively damp torsional vibrations and resist failure under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide enhanced spring support, reduce stress concentrations, and increase strength and reliability. While engagement with the 6-pad, spring-centered race disc is harsher, shifting is faster. This disc is particularly recommended for larger clutch sizes to absorb more heat.

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, using select ceramic friction materials for high heat tolerance and maximum performance.

Recommended Use: Recommended for high horsepower street or race use, ideal for applications where durability, aggressive engagement, and high performance are essential.

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, equipped with the 2.0 L4 GAS FI 2000cc engine.

Good for the price but not as roomy as a North Face.
Size: X-Large, Color: Black
The jacket is lightweight and warm. It isn’t as roomy as a North Face puffer jacket but fits me fine (6’1, 190). I find that when I zipper it to the top, it irritates my throat area a little. The color is what showed in the picture.

Not very puffy puffy jacket
Size: XX-Large, Color: Denim Blue
At xxl the shoulders fit well and perhaps the first jacket where the sleeves came down to my wrists and not halfway to my elbows if I reached forward. Love the zipper. The zipper pull is at my right hand side. It is where i would use my right hand to engage and pull it closed. The zipper glides smoothly. The hood is voluminous. There is no string available to control the fit of the hood. As it us the hood is much too large. It makes the jacket look cheap and unfinished. The jacket would be immeasura bly better if the was a bit more fill in the body and a string pull in the face of the hood to bring the fit closer.

It's thin but it's good for cooler mornings and windy days
This jacket is not super thick or sherpa/fleece lined. But it's great for cooler temperatures, windy days, or staying warm while out on a boat. It's lightweight, cuts the wind and is great for layering. Folding it into the bag makes it ideal for travel and camping
