Description: The ZX4-HDR4 kit by ACT features their renowned Heavy Duty pressure plate coupled with a 4-pad rigid race disc. Utilizing an exclusive diaphragm design, ACT's Heavy Duty pressure plates enhance clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a rigorous four-stage, heat-treating process to ensure unparalleled performance. Precision cover stampings contribute to the rigidity and consistency of ACT pressure plates.

The 4-pad rigid race discs are crafted with high-quality ceramic friction materials and feature a chrome-moly hub heat-treated for strength and durability. The lightweight, rigid design enables quicker shifts and ensures smooth, trouble-free service. While engagement with the 4-pad rigid race disc is harsher, shifting is faster. This disc is particularly 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, utilizing select ceramic friction materials for high heat tolerance and maximum performance.

Recommended Use: Recommended for race use only, ideal for drivers seeking high-performance clutch systems optimized for competitive racing environments.

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

Vehicle Fitment: Compatible with various Mazda models, including the 2006-2013 Mazda 3 Mazdaspeed and the 2006-2007 Mazda 6 Mazdaspeed equipped with the 2.3 L4 GAS FI 2260cc | DOHC engine.

Great for Sun Allergy Rashes!
Scent: Unscented, Scent: Unscented
I have an autoimmune disease called Sjogren’s Disease. With that, for me, comes a sensitivity to the sun in the form of sun allergy rashes. Also with that, I did a deep dive on the best sunscreens and read a lot of reviews on here. I put some of the outer sides of elbows where my sun allergy rashes were when I received it. There was slight sting, but the skin there was already slightly broken. I really love the texture of it, how it feels on my skin and that there's no white cast. It’s moisturizing, too, with no greasiness. Absorbed really well.

The best mineral sunscreen
Scent: Unscented
I’m so impressed by this sunscreen! I’ve been using mineral sunscreens for years and this blows every other one I’ve tried out of the water. It is silky smooth and applies so easily, absorbs well and doesn’t feel greasy or heavy. It doesn’t leave a white cast but it still protects very well! Of course like any sunscreen it’s only as effective as your usage, so reapplying is paramount. The unscented truly has no smell to it, which is something I appreciate. Using it for the first time, neither myself or my fair kiddos got sunburnt. It’s just all around a fantastic, clean mineral sunscreen and will be my go to from now on!

Wellness Staple for Sensitive Skin
Scent: Pear & Coconut Water, Scent: Pear & Coconut Water
I’m becoming much more intentional about the products I use on and around my body, especially while traveling, and this sunscreen ended up being one of the best things we packed for our girls trip to Mexico. My friend has extremely sensitive skin and typically reacts to a lot of sunscreens, so we wanted something mineral-based, reef safe, and more wellness-conscious overall. We split one bottle between the two of us over about five days, and honestly it held up really well. It felt lightweight for a mineral sunscreen, blended in better than expected, and didn’t leave our skin feeling greasy or irritated in the heat. Most importantly, neither of us experienced sensitivity issues or breakouts during the trip. I also appreciated the peace of mind of using something reef safe while spending so much time in the ocean. It’s one of those products that aligns well with a more mindful, health-focused lifestyle without sacrificing effectiveness.

Love the scent
Scent: Tropical Breeze
This sunscreen has such a great scent and is easy to apply with no white cast. Skin doesn't feel clogged or sweaty. Easy to apply and distribute. Like that it's a zinc oxide sunscreen that is doesn't leave a white cast and has a wonderful tropical scent. Wish it came in SPF 50 or higher.
