Stoptech Cross-Drilled rotors are 1-piece, drilled, 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. 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, Stoptech Cross-Drilled covers more than 2500 applications, all machined in Stoptech Cross-Drilled California manufacturing center. Every Stoptech Cross-Drilled rotor is a direct replacement for a factory brake rotor, allowing the retention of factory calipers in the system.

 

Most Stoptech Cross-Drilled rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Stoptech Cross-Drilled 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.

 

Every Stoptech Cross-Drilled 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.

 

Stoptech Cross-Drilled 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.

 

Stoptech Cross-Drilled 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.

 

Stoptech Cross-Drilled 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 Stoptech Cross-Drilled'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 Stoptech Cross-Drilled's continuous improvement process that helps to reach established targets for hardness and tensile strength. Many of Stoptech Cross-Drilled'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).

Expansive and accessible
Format: Hardcover
This book broadened my thinking on project management within business. It highlights the portfolio angle, and relevant topics like how to drive adoption/usage and broad idea capture. The case studies bring things to life as well as the `list based' approach to best practices. I'd recommend it for someone who wants to understand the latest thinking in the project and portfolio management field and tie it back to business value and business strategy.

Great Reference
Format: Hardcover
The book provides a complete, high-level overview of Project Portfolio Management (PPM). As the title suggests, it covers both Portfolio Management and Project Management. The book is a great reference for PPM concepts. I personally found the first few chapters of the book very interesting, because it talks about portfolio management in a different manner than what you would read in other books such as PMI's The Standard for Portfolio Management. The book has been written in an easy-to-read style and it provides pragmatic ideas on how to best help an organization manage their portfolio, using concepts such as: Anchoring, superior estimation, batch vs. ad hoc prioritization, one portfolio or many, private collection of information, winner's curse, innovation vs. improvement projects, accounting vs. project management, etc. In short, the book is a recommender for all PPM practitioners!

Great introduction to work management
Format: Hardcover
I am not an expert in project or work management and found this book really useful and readable. Moore does a great job of looking beyond standard project management terms and frameworks and helps re-frame project management as a strategic, not a tactical concern.

Nice update
Format: Paperback, Format: Paperback
I really like this version of a practice test. It covers pretty much all the topics I wanted to learn more about (like math related) and the fact that’s it’s current for this year is great. I didn’t want to practice with old information. It also has a well-structured approach to mastering the digital format. I feel like it properly prepares you for the actual feeling of doing the test. My favorite thing has to be the mini test. Sometimes I think I’m ready for a test but end up realising I still have a long way to practice so it’s great to have a tool that helps with that. Just overall, its practice is very reasonable so as long as you take the time to really take advantage of this book, the SAT will be a breeze.
