Product Description: HD/Race Rigid 4 Pad Clutch Kit

The HD/Race Rigid 4 Pad Clutch Kit, identified as the ZM10-HDR4, is engineered by ACT to deliver unparalleled performance for race applications. With a weight of 25.4 pounds, this kit provides an impressive torque capacity of 399 ft/lbs, surpassing OE standards by 87%. Crafted with ceramic disc material, it features a clutch disc diameter of 8.8 inches (224mm) and an input shaft diameter of 0.9375 inches.

At the core of this kit lies ACT's renowned Heavy Duty pressure plate, featuring an exclusive diaphragm design that increases clamp load, reduces deflection, and maximizes clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring exceptional performance under extreme conditions. Precision cover stampings provide essential rigidity and consistency for enduring performance.

The clutch kit integrates ACT's 4-pad rigid race discs, constructed with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability, enabling quicker shifts and smooth operation. While engagement may be harsher, shifting is faster, making it ideal for smaller disc sizes in smaller engines, where performance is crucial.

Key Features:

  • Feel: Light to moderate pedal effort, aggressive engagement, increased gear rattle.
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design, though the 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: Exclusively recommended for race use, delivering uncompromising performance on the track.
  • 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

For racing enthusiasts seeking uncompromising performance and durability, the HD/Race Rigid 4 Pad Clutch Kit from ACT is the ultimate choice, designed to deliver outstanding performance on the track.

Surprisingly comfortable and stylish wrist rest!
Color: Walnut Wood, Size: Large
This wrist rest is the perfect compliment to my desk set up. I was hesitant about buying a wood product like this, but I’ve been pleasantly surprised how comfortable and smooth it is during extended use. For the price, it feels like a premium product, and I love that it stays put with the rubber feet. The size is perfect for a full-size keyboard, with just the right thickness to keep your wrist and palms comfortable. If you’re looking for an elevated way to decorate your desk while protecting your wrist, this is a great choice.

Great wrist rest with a modern look!
Color: Walnut Wood, Size: Medium, Color: Walnut Wood, Size: Medium
This is a great looking addition to my desk. It’s a just the right length to fit my keyboard and I love the walnut coloring! It’s real wood and has nice rubber feet on the bottom to keep it from moving around. The angle is nice for my wrists and it’s easy to clean with just a damp cloth. If I ever wear this one out (which I doubt) I’d buy another!

Super comfortable - much better than memory foam wrist rests!
Color: Walnut Wood, Size: Large, Color: Walnut Wood, Size: Large
Get this wrist rest - you won't be disappointed. Had ergonomic keyboards and have tried memory foam rest in the past and this is much better. Smooth wood, perfect height and very supportive to keep wrists in neutral position when typing. Got the 17.3" and like that there's ample room to not feel squashed, but probably could have done with the medium length. Great angle for my mechanical keyboard. Love it!

What an excellent wrist rest! Except for this one thing....
Color: Walnut Wood, Size: Large
This is a solid piece of wood with great quality. Fantastic large rubber grips on the bottom (left and right sides only). Pro: I use it for editing and gaming. And though I thought the wood might be a bad choice in the long run, it turns out it's pretty nice. Not as comfortable as a gel rest but I knew what I was getting when I ordered it. I buy things for function AND aesthetics. I love how this looks. The uniqueness is really something. I got the natural one instead of the black so that the grains and lines can be easily seen. Con: Unfortunately, after almost 2 months, the wood has warped some. Not enough to effect my typing but, enough that I notice it. The warp is the kind where the opposite angled corners go up and down. While the other 2 corners are fine. In my case, the top left and bottom right, when pressed independently, rock the wrist rest. The top right and bottom left stay grounded. This is why I took a star off. Because there's no way this should be happening. So, looks and quality are up there. The rubber grips are solid. Why it's warping is puzzling to me. NO liquid wasted on it. Or, extreme temperature changes have happened. I've made sure the rubber grips. And that the surface the rest sits on (a glass mouse scrolling top by Superglide) is clean. Yet, I get this slight rocking. It bugs me this all happened right after the return window closed. I would've simply exchanged it. I love it too much. I mean, this is, again, a SOLID piece of wood. Maybe this won't happen for everyone. I mean, it's wood. Eh I would still recommended this regardless.

Fantastic Product
Color: Walnut Wood, Size: Small
This is very nice! I type all day for my job and this made a big difference. It's very comfortable and supportive. Im allergic to latex rubber, which is in most gel options. It's really nice to have a safe, effective alternative
