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.

Amazing recipes, but a visually exhausting thing to read
Format: Hardcover
The recipes in this book are amazing. Reading through them and flipping back and forth through the pages you can tell Molly put a lot of time and attention into making powerful recipes packed with flavor, with all of them being incredibly approachable in actual technique. There are too many good things to call out with this collection of recipes. But existing as an easily digestible and referenced cookbook, it kind of sucks. The editing in this book is supposed to be *fun*. There are random font styles in every page and sometimes there are weird lines that become wavy. There are points in the book where there’s suddenly a cocktail recipe thrown into a chapter about salads or sandwiches. Great sounding cocktails, but ones you’ll need to scan the recipe list for since how would you be able to know which chapter it was thrown into? At the end of the day I feel like a cookbook should be an easy tool for someone to use in the kitchen when there’s already so much going on. The book is visually exhausting to read, but looks very very delicious to make from.

Nice recipes, AWFUL font
Format: Hardcover, Format: Hardcover
I loved Cook This Book. Mine has a permanent crease on the Caesar salad page and the other recipes I have tried have all been winners, so I was excited to get Molly’s next book. My initial browse through the recipes has me excited to try them out, I just cannot understand the choice of this awful font. It is so difficult to read and make out the letters. I can’t imagine how difficult it would be for someone with visual or reading impairments. There is even a fully black page with dark blue font that is basically unreadable (the picture I included is very kind, in real life the contrast is extremely minimal). It’s such a huge distraction from what otherwise appears to be a nice collection.

Useful
Format: Kindle
Wonderfully written with lots of good advice. I think a lot of young people are lost in the world because a lot of this stuff is not taught in school anymore, at least not where I am. This would be a great resource for kids that are aging out of foster care and need the guidance of how to manage life. This could also serve to guide adults leaving prison. I wish I would have had something like this when I was becoming an adult because I didn't have the best guidance and figured a lot of stuff out on my own. I will make sure both my kids have a copy to guide them in the event I'm not around to help them. Overall, great book and I'm glad someone wrote it. Lol
