Description: The ZM8-HDG4 kit by ACT features their renowned Heavy Duty pressure plate. These pressure plates utilize an exclusive diaphragm design to enhance 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 in this kit features a spring-center to properly 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. With the 4-pad spring-centered race disc, engagement is harsher, but shifting is faster. This disc type is 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, ideal for applications where durability and high performance under extreme conditions are essential.

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

Vehicle Fitment: Compatible with various Mazda RX-8 models ranging from 2004 to 2011, equipped with the 1.3 R2 GAS FI 1308cc engine.

Too soon to tell. Does hold All my cards. good looking wallet. However, once all cards are in place, very stiff and thick. As I said, Time will tell. Hope it will soften with use. Saved my old one ...Just in case. Patty

I expect to be using it for years
Color: Brown, Style: Modern
Very well made product. It matched the description in every way. It is still a little stiff but I know it will stretch into a comfortable use product because that is how leather is. Why did you pick this product vs others?: I liked the retro look that was offered Card capacity: including hiden pockets there are 13 as described. Comfort: nicely smooth and fits well in my pocket.  Slimness:   A smidge bulkier than expected but not a problem Value for money: definitely worth the price. Smell: I could smell the leather tanning.  Quality: My girl friend is proud to have me produce it at the bar.

Very roomy
Color: Coffee, Style: Modern
It's great. I feel secure with the RFID, the leather is soft and looks great. It has many pockets for cards so that I can spread out my cards. This makes it slim in my pocket. This is a very nice wallet; I recommend this as a great gift or a replacement for yourself.
