Description: The PO2-HDR4 kit features ACT's popular Heavy Duty pressure plate with an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. The pressure plate undergoes a four-stage heat-treating process for superior performance. Precision cover stampings ensure rigidity and consistency. ACT's 4-pad rigid race discs are made with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for added strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. This disc is well-suited for smaller disc sizes in smaller engines.

Honestly, I never thought I would enjoy studying this much!
Format: Paperback, Format: Paperback
I was so grateful for this book's excellence that I opened the Amazon website during my break to write a review. I wanted to brush up on my skills before taking my first Python class in the fall, so I was looking for a beginner's book I could study on my own over the summer. Since I had no coding experience, I needed a book that explained even the smallest details step-by-step. I've been studying with the goal of completing two chapters a week since August. I'm currently on Chapter 8, and it's been so much fun! Honestly, I never thought I would enjoy studying this much. I spent two days on practice problem 8-8 (though I spent most of the time lying on the couch screaming, "Why can't I do this?" than actually solving the problem). However, after some time, I reconsidered and re-tested the problem, and today, on the third day, I finally figured out what the issue was! I resisted the urge to ask AI or look at the GitHub code the author had posted. Instead, I solely relied on the book to solve the problem. The information in the book was more than enough. I'm proud of myself! If you're a beginner like me and just starting out with Python, I highly recommend this book! It seems unlikely I'll be able to finish all the remaining chapters and projects before the fall semester, but I'd like to take the time over the weekend to finish this book if possible. I have no doubt that the detailed, helpful explanations and systematic practice problems will help me solidify my fundamental Python coding skills.

I love how Charles wrote this book, I read it slowly throughout the year and was easily able to digest all the examples and illustrations provided and have got a better and broader understanding of Code, software, hardware, batteries, lightbulbs, history and much more!
