Product Description: HD/Race Rigid 4 Pad Clutch Kit

The HD/Race Rigid 4 Pad Clutch Kit, designated as the ZM12-HDR4, embodies ACT's commitment to high-performance clutch solutions. Weighing 25.4 pounds, this kit delivers a remarkable torque capacity of 399 ft/lbs, surpassing OE standards by 87%. Crafted with a ceramic disc material, it features a clutch disc diameter of 8.8 inches (224mm) and an input shaft diameter of 0.9375 inches.

At its heart lies ACT's renowned Heavy Duty pressure plate, renowned for its exclusive diaphragm design. This design elevates clamp load, diminishes deflection, and maximizes clutch longevity. Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring unmatched performance. Precision cover stampings provide the necessary rigidity and consistency crucial for enduring performance under the most demanding conditions.

The clutch kit integrates ACT's 4-pad rigid race discs, engineered with premium ceramic friction materials. The chrome-moly hub is heat-treated for enhanced strength and durability. The lightweight, rigid design facilitates quicker shifts and ensures smooth, trouble-free operation. While engagement may be firmer with the 4-pad rigid race disc, shifting becomes noticeably quicker. This configuration is particularly well-suited for smaller disc sizes in smaller engines.

Key Features:

  • 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: Meticulously engineered, precisely assembled, accurately balanced, utilizing select ceramic friction materials for high heat tolerance and maximum performance.
  • Recommended Use: Designed for race use only, offering unparalleled performance in high-performance applications.
  • ACT Difference: Rigorously tested, ensuring 100% clamp load and dynamically computer balanced for smooth operation even at high RPMs.

Vehicle Fitment: This clutch kit is compatible with a range of Mazda MX-5 Miata models from 2016 to 2018, including various trim levels equipped with a 2.0 L4 GAS FI 1998cc engine. Compatible models include:

  • 2016-2018: Mazda MX-5 Miata Club, GS, GT, GX, Grand Touring, Sport
  • 2017-2018: Mazda MX-5 Miata RF Club, RF GS, RF GT, RF Grand Touring

Owners of these Mazda MX-5 Miata models seeking uncompromising performance can elevate their driving experience with the HD/Race Rigid 4 Pad Clutch Kit from ACT.

Difficult/impossible to unscrew plastic cups (in order to recharge the vibrating/blinking device)
Color: Orange
Generally, I don't leave feedback on items purchased. However, in this case, I feel compelled to do so in hopes the mechanical engineers (of this product) will take my input to heart and ultimately modify it. First the pros... - I have 2 high-energy dogs (Jack Russell Terriers) who love their toys (e.g., chewing bones, tug-of-war, etc.) but usually get bored with them rather quickly. - This interactive PetDroid ball, however, keeps them busy for a long time. - In fact, my smaller dog (Max) knows its storage location and sits (as early as 6 AM) in front of the cabinet so that I give him "his ball". It keeps him busy for up to 1-2 hours at a time. - Max is literally addicted to the PetDroid ball... his determinant play with it makes me laugh all the time. Now, the cons... - After several days of play, the exterior looks chewed up quite a bit. That's no problem though. - Unfortunately, the interior "threads/grooves" of the two plastic cups (for closing/fasting) are very tiny. - Thus, after an hour-long hard play, it is almost impossible to unscrew the 2 plastic cups in order to recharge the interior device. - It appears the 2 cups somehow come off track and get realigned from the inside. - At that point, I cannot unscrew the PetDroid ball in order to recharge the device.... and without the blinking/vibration, this toy is no longer fun for play. - Ultimately, I had to place the bottom half of the ball into a vise and then use a plumbing wrench to untwist it. Proposed Solution: - Increase the size of the plastic cups' interior threads/grooves so that they won't get realigned/come off track. - This would mitigate the current dilemma of NOT being able to unscrew the ball in order to recharge it. In my view, this should be a relatively simple fix and significantly improve the durability of this product. Thank you for your time.

Good fun and entertaining!
Color: Orange
A really fun interactive toy for your dog! It's pretty erratic and really gets him chasing it. The included soft cover was kinda hard to install and then it's hard to turn it off and on with the cover on, I feel like the cover didn't really improve it at all, sure it's louder without the cover but I feel like dog also likes it that way, he likes loud squeaky toys and this thing making a bunch of noise is appealing to him. We have mostly hardwood floors so it really gets moving, I'm sure on carpet it would be a bit quieter and maybe even a bit slower to move around but on hard smooth surfaces this things can really get zipping around abd get some speed to make him chase it. Overall a fun and entertaining toy.

Not the Fetch-Fest I Hoped For
Color: Orange
I had high hopes for the PetDroid Interactive Dog Ball, especially with the newly upgraded features and promises of durable, motion-activated fun. Unfortunately, it didn’t quite live up to expectations for my furry friend. Here’s why I’m giving it 2 stars. Promising Features, Lackluster Results The idea behind this toy is fantastic: a durable, motion-activated ball that would entertain my dog without much effort on my part. The ball is supposed to roll around on its own, keeping my dog engaged and active. However, in practice, it just didn’t capture my dog’s interest. Durability I will give credit where it’s due: the ball is well-made and seems durable. It can withstand some rough handling, which is great for more aggressive chewers. Unfortunately, durability doesn’t mean much if your dog won’t play with it in the first place. Motion Activation The motion activation feature is hit or miss. While the ball does move around as advertised, it didn’t seem to move in a way that intrigued my dog. He gave it a sniff, watched it for a minute, and then walked away, unimpressed. I tried multiple times to get him interested, but he simply wasn’t having it. Lack of Engagement The biggest issue is that the ball just didn’t engage my dog at all. It might be more suitable for a different personality type or breed, but for my pooch, it was a total flop. He’s usually quite playful and curious, so I was surprised by his lack of interest. Final Thoughts Overall, the PetDroid Interactive Dog Ball might work for some dogs, but it was a miss for mine. If your dog is easily entertained by automated toys, it might be worth a try. However, based on my experience, I can’t wholeheartedly recommend it. Pros: Durable construction Motion-activated as advertised Cons: Did not engage my dog Motion activation wasn’t intriguing enough Might be more suitable for specific dog types or personalities If you decide to give it a shot, just be prepared for the possibility that your dog might not find it as entertaining as you hope. For us, it’s back to the drawing board for a more engaging toy.

Pup Loves It, Some Other Notes
Color: Orange
We've had this for about six months and my 75 lb, 14-month-old German Shepherd pup LOVES IT. Her favorite is "Crazy Bouncing Mode." In fact, she doesn't care much for the normal mode. She chews it a lot - even drops it in her water bowl at times - and it's still going strong. This is a great purchase. It's nice hands-off entertainment. Do know that it is heavy compared to a normal ball - if your pup likes dropping it on the ground like mine does, it will land with a hard "thud," even with the included sleeve. Hopefully you don't have downstairs neighbors. Also know that the cover that goes over the charging port is removable and your dog may choke on it if they chew it in just the right manner. Definitely only let the pup play with it while supervised. All in all, great toy.
