Power Slot Rotors

Power Slot rotors are 1-piece, slotted, direct replacement discs for your factory brake system and stock calipers. They offer improved cooling as well as other advantages the competition doesn't offer. Launched in 1998, Power Slot was the first premium slotted replacement rotor program in North America. Innovations include e-coating, double-disc grinding, full machining, mill balancing and center-split castings, as well as the availability of directional vanes, cryogenic treatment and the use of Power Alloy. Today, Power Slot covers more than 2500 applications, all machined in Power Slot's California manufacturing center. Every Power Slot rotor is a direct replacement for a factory brake rotor, allowing the retention of factory calipers in the system.

Most Power Slot rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Power Slot has improved the design by using directional (left- and right-handed) vanes to improve cooling. This represents a distinct upgrade from the original equipment rotors, which usually feature a straight vane or pillar vane design. The directional vane is a more efficient air pump. The resulting increase in airflow translates into greater resistance to brake fade and faster recovery from temperature spikes generated by aggressive braking maneuvers.

Power Slot rotors feature a signature "short slot" design. The slot improves brake system performance by wiping away the debris of used friction material that otherwise accumulates between the rotor and pad. This keeps fresh pad material exposed to the rotor surface and helps prevent pad glazing. The edges sweeping the pad slightly increase the effective coefficient of friction, or "bite", amplifying brake system response to pedal input. By providing an escape path for water, slotted rotors can also improve initial brake response under wet conditions.

Every Power Slot rotor is finished with a black e-coating on both sides of the hat, inside the cooling vanes and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these areas can lead to installed lateral runout issues.

Power Slot rotors feature a double disc ground, taper free finish. Double disc grinding ensures parallelism, eliminates run out and provides near perfect disc thickness variation (DTV). Double disc grinding leaves a non-directional finish on the friction surface area for more effective pad and rotor break-in. This special finish also provides quieter and smoother stops.

Power Slot rotors feature 100 percent fully machined finishes including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component.

Power Slot brake rotors are mill balanced to a tolerance of less than 2 oz-inch. This additional machining operation reduces feedback associated with rotor vibration and provides a smooth, confident application of braking force.

Center-split core castings provide proper heat transfer and thermal efficiency, resulting in superior braking power and safety.

Power Alloy metallurgy is another unique feature in many of Power Slot's rotors. Quality and performance live inside the rotor too. Choosing the correct foundry partner and working to improve the metallurgy are all part of Power Slot's continuous improvement process that helps to reach established targets for hardness and tensile strength. Many of Power Slot's top-selling part numbers are cast using this Power Alloy iron specification, an enhancement in the carbon and molybdenum content of the iron. Carbon and molybdenum promote crack resistance and improve noise, vibration and harshness (NVH).

This is a good very distant overview
Format: Paperback
Sometimes I need a really simplistic overview of an entire subject before I feel comfortable sitting down to learn it. Like if you are going to learn about, say, 13th Century France you might want to know just a little about the major issues of the entire century before sitting down with a text book. This book is good for that. It's short, it gets you started with the main keywords, and at the end you have a good picture of what the language can do. And you can get to the end in a day or two. It's very well written, well organized, clear, and very very limited in scope. But if you read it, you will be in good shape to start getting down to business with working with SQL with a more advanced text. This book, in my opinion, was well worth the money and the read even though ultimately I turned to something far more advanced.

Does a good job, but too much philosophy.
Format: Kindle
I'm about halfway through this book. I have a condition that makes it hard to read. This book does a good job of teaching SQLite but spends too much time stressing the importance of comments and style. I agree, that these things are important, however, not to the audience of the book. The reader would have been better served by getting into the grit of SQL syntax and which keywords to use when versus ensuring that every query had a comment block with name, date, and description. Moreover, requiring every reader to download a prewritten database to work from and special utilities to follow along takes away from the learning experience. That said, you will learn the basics about SQLite, and by the end of the book be able to handle most problems you'll encounter when developing an application.

Great book!
The free promotional items the company gives you just for buying this product alone make it worth the five stars I have given it, and the product itself is amazing. I should start by noting that I received this product about 5 days ago and I am currently halfway done with it. This is not a book that teaches you the very basics of computer programming and assumes that you already have a basic grasp of the fundamentals such as arrays which you definitely should if you are even the slightest bit interested in learning SQL. The book begins by teaching you about what the program is, how it is becoming a valued skill in the world, and why it is a better programming language than others. It makes a language that most people consider highly advanced and more and more difficult the more you use it very easy to grasp in a way that could potentially change your entire career. I am not a computer science expert myself and have only a basic understanding of programming language, mostly java, but I was able to read this book and understand almost all of it without a problem. My computer science friends are even surprised by how much I was able to learn about this programming language that they consider impossible in such a short amount of time. I highly recommend this product if you have any interest at all in learning a new programming language or just giving yourself another skill because they make it very simple to learn. Disclosure: I received this product for free or on a promotional discount for my honest review and they are 100% my own opinions. However everyone has their own opinion on this product. I did not receive payment other than receiving the product at a discounted rate and I am not required to give a good review. I know how important my reviews are to people who are interested in buying this product, because everyone should be reading reviews before they purchase a product. What I include is what I actually think about the product and my opinion alone. My reviews accurately reflect my views on this product and any 5 star product I would recommend to both my friends and family as well as purchase at full price. This disclosure is in accordance with the Federal Trade Commission’s Guidelines on Testimony and Advertising. I provide honest reviews that describe the product it entirety both the positive and negatives (if there are any). If my review was helpful to you, would you please vote yes!
