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

Must have this if you have an iPad.
Fits my iPad perfectly. Makes storage of the power cord easy. It also protects the iPad when not in use.

Perfect for my iPAD, cash, phone, & more
Size: 12.9 inch, Color: Indigo
I searched Amazon a few different times trying to find exactly what I was looking for. We're traveling out of country and I needed a couple of very specific things in a bag for my iPad. It has the padded space for the iPAD, then beside it is an equally sized space for whatever - money bag, etc....for me. T here's a front zipper pocket with a smaller pocket included holders for 2 pens. My time and energy paid off by purchasing this bag. The iPAD slides in lengthwise making it easily accessible along with the cash bag I'll be accessing frequently. Its qualit y, it looks very nice and its lightweight. I'm a happy camper. I recommend getting this bag. Oh, I will also carry my cell phone in the bag too.

A Very PROfessional looking bag for all my iPRO Mobile Devices!
Size: 13.3-14 inch, Color: Dark Gray
Moko products usually meet my expectations and this little bag is no exception. It’s the perfect size for an iPad in a fully enclosed case. The front pocket is ideal for cords, backup charger battery, pens, notepads, iPhone, etc. We (husband and wife) are both in our 80’s and sometimes need to take our iPads to medical appointments because it’s often hard to see everything we might need to see on a regular iPhone screen. We bought a dark blue one in January for my husband to safely take his new iPad to work so he could read kindle books during his breaks. The day after I ordered it, he had to retire under VA Disability. Still, it has come in handy as we take care of paperwork, etc. I liked his so much that I ordered this gray one last week. The size, style, colors, etc make them look very professional. The bag is small enough that even I can lift and carry it. (It’s too small for use with a full-size laptop especially if it has a case of any kind.) I have the 2025 iPad Pro (M5) and my husband has the 2025 iPad (A16). We both have the 2025 iPhone 17 Pro — mine is the regular size and his is the Max. Both are in completely enclosed cases. It is a necessity to have a secure way to use our mobile devices away from home, and these bags are perfectly compatible with everything we need to carry around in them as protection for our valuable devices. The MOKO cases are stream-lined, easy to use, not bulky but padded enough to give protection. Best of all, the price is quite good for an item of this quality. At $30 @, I suspect they could possibly outlast us! They also should be easy to spot clean if necessary. I find I can keep my magnetic paper-feel screen in the inside pocket to use with my iPencil Pro, which I can store in the smaller front compartment. In fact, I will probably keep all my accessories in the bag, then just add my iPad when I need to take it with me. I’m glad we both have our own and highly recommend this if you are looking for a bag for this purpose.

Very impressive and cute carrying case
Size: 12.9 inch, Color: Purple Starry Sky, Size: 12.9 inch, Color: Purple Starry Sky
I've been looking for the "perfect" ipad carrying pouch for a while now and this one is the closest I've found. I use my ipad primarily for art so I always have a stylus, a sketchbook and various odds and ends with me. My 13 inch ipad while in it's bumper case fits in the sleeve easily without the stylus attached and in the main compartment with the stylus attached. There is also enough room for an extra sketchbook/kindle/keyboard in the main part of the bag The zipper quality is nice and I like the feel of the zipper pulls. The handle on the top is very convenient. The crossbody strap is the only thing I'd be a little concerned about because the attachment hardware is plastic but it doesn't feel flimsy at all. The padding is a good amount and I think I would feel safe with my ipad in it with a less robust or even no case. Also I'm just really happy that it had some fun and cool colors available, I'm tempted to pick up a more 'business like' color in the future.
