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).

Understand your loss. Celebrate your gain. Live!
Format: Kindle
A quick look at what makes us human; our principal line of relationship to the Cosmos. Maybe not always reverent, but always livable and believable. This is a book, a primer, on how to deal with the mess of life. Written with enough seriousness and tongue-in-cheek humor to be readable and thought provoking.

An Invitation into the Heart of Reality
Format: Kindle
I love reading Anne Lamott. She helps me feel that it’s okay to be human. She helps me see that prayer is human. It’s the most natural thing you can do. And, really, everybody does it, whether they know it or not. In this delightful book, Ms. Lamott reflects on what she calls three essential prayers: help, thanks, and wow! Such human expressions! She invites us, the readers, into her perspective on life, infused as it is with both the mundane and the mysterious. There are times when it is even threatening. But we are not alone. We have each other, and we have God. (Or, better, God has us.). I don’t know that Ms. Lamott would want to be called an optimist, but she certainly sees the good in the bad (or, maybe after the bad). Life is both, she seems to say, but all is okay. So we ask for help when we’re wise enough (or desperate enough) to do so—both for ourselves and others. And we say thanks because life is full of reasons to be grateful. And there is so much beauty around us—and tragedy too—that we cannot help but erupt with wow! I urge you to read this book. Perhaps, as you read it, you will feel as I did reading it, that you are in a conversation with someone very wise and very compassionate and very real.

Another Thanks and Wow by Anne Lamott!
Format: Hardcover
I was first introduced to Anne Lamott's writing about 25 years ago when I read her book, Bird by Bird. It was a book about how to write and from that moment she became one of my favorite authors. Help, Thanks, Wow is a wonderful book that I have underlined and reread over and over again. Her writing has a voice that many of us can relate to. It's honest and you can feel her pain. She writes with humor to balance the good with the bad. Something that is so important to learn as we go through life. Her descriptions help you see, feel, and smell when she describes "autumn...the colors are broccoli and flame and fox fur. The tang is apples. The rot smells faintly of grapes..." She tells us how to ask for help when you can't do it all by yourself, but how important it is to say thank you, thank you, thank you and Wow for all the things you are grateful for. I loved when she wrote about how service to others is joy ,but how important it is to be kind to yourself. One of my favorite passages was this one, "This morning at six when I awoke, loneliness was sitting on my chest like a dental X-ray apron, even though I was buried in hairy dog love. Help, I am sad and lonely, and already it looks like today is going to be too long. I prayed...I did a kindness to myself, as I would have a troubled friend..." Her descriptions are all like this one and easy to relate to. I loved this book and have given it to friends who have then bought it for other friends. It is definitely a WOW!!!!

Not bad, but not my cup of tea
Format: Hardcover
After seeing Anne Lamott on TV, I was impressed with her and checked out this book on Amazon. The reviews were good, so I ordered it. I was a bit disappointed on receiving it, as I didn't like the shape of the book (too small) and I didn't like the type style (too hard to read). Then, I struggled to get into the book. I like to highlight insights in inspirational books, and I simply didn't find anything to highlight in this one. I think Anne Lamott is a lovely person and I understand how a lot of people liked this book. However, it just didn't bring any new insights to the table for me and it wasn't written in a way that I found compelling. The good news is, it wasn't too hard to finish, since it is short. I passed it on to someone I hope will enjoy it.

I Just Want to Read It Again!
Format: Hardcover
***** What a brilliant book! When I first received "Help, Thanks, Wow: The Three Essential Prayers" I too was so disappointed that it was such a small book--tiny, short, maybe an hour's read. Ah, but what an hour! Precious. And to be completely truthful, this book actually took me several hours to read, because I had to put it down, think, cry, laugh, and even--yes--pray. This book is worth your time and attention. I am so glad that I have it in hardback because I will keep it forever and reread it regularly; I am finished reading it and I just want to read it all over again. It is a book about getting through life. It is rich, raw, funny (hilarious, like all Annie Lamott) and written in language so stunning I would have to stop and just read and reread sentences. I feel as though my life has been broken open with a whole new attitude towards prayer, and even more, towards being alive. This is not a religious book at all, but a book for anyone who is spiritually-oriented and maybe especially for those who aren't, because the author writes about prayer in a way that every single person can relate to. This is a book about being real and true and simple and clear and about living a worthwhile life. Don't miss this book. Highly recommended. *****
