Description: The ZM4-HDR4 kit by ACT includes their most popular Heavy Duty pressure plate matched with a 4-pad rigid race disc. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to increase clamp load, diminish deflection, and extend clutch life. Each diaphragm undergoes a four-stage heat-treating process for exceptional performance. Precision cover stampings ensure rigidity and consistency.

ACT's 4-pad rigid race discs are constructed with high-quality ceramic friction materials and a chrome-moly hub heat-treated for strength and durability. The lightweight, rigid design facilitates quicker shifts and smooth, trouble-free service. Although engagement with the 4-pad rigid race disc is harsher, shifting is faster, making it well-suited for smaller disc sizes in smaller engines.

Key Characteristics:

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

Recommended Use: Recommended for race use only, particularly suited for applications 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.

I will keep buying these
Size: 3 Big Kid, Color: Black Orange, Size: 3 Big Kid, Color: Black Orange
This is the third time I have purchased these shoes. Every time my son grows out of them I buy the next size up. His favorite color is orange, so he loves the look of these. They are also soft mesh around the toes, which he loves so he can wiggle his toes. These are durable and well made. The pair i purchased before these is still wearable, just too small for him now. These are his daily shoes. The price has gone up since my first purchase, but they still are not unreasonable for how long they last. He is an active boy. He climbs trees, runs, and plays hard. So for any show to last 6 months when he wears them daily it shows the durability. It also shows that these shoes have tread on them thay stops him from slipping. He is able to move around freely and never has issues with grip. He puts them on without difficulty.

Comfortable, Durable, and Perfect for Active Kids
I recently purchased the Under Armour Kids' Grade School Assert 10 Sneakers for my child, and they are excellent! These sneakers are lightweight yet supportive, making them perfect for everyday wear, sports, and outdoor activities. The breathable mesh upper keeps feet cool, while the cushioned midsole provides comfort and shock absorption during running or play. The sneakers also have a durable rubber outsole that provides excellent traction, reducing the risk of slips during active play. The sleek design and modern style appeal to kids, and the shoes fit true to size, making them easy to wear for extended periods. Overall, the Assert 10 combines comfort, durability, and style, making it a reliable choice for active kids. They hold up well after repeated wear and are easy to clean, making them a great value for parents. Pros: Lightweight, breathable mesh upper Cushioned midsole for comfort and shock absorption Durable rubber outsole with good traction Sleek and modern design appealing to kids True-to-size fit and easy to clean Cons: Minimal color options in some sizes Laces may require supervision for younger children Overall: The Under Armour Kids' Grade School Assert 10 Sneakers are comfortable, durable, and stylish, perfect for active kids who need reliable everyday footwear. Highly recommended!
