Designed and engineered in-house in the UK, the MMR differential insert kit for the BMW F2x and F3x chassis is designed to limit movement in the factory diff mounts to maintain proper suspension geometry when cornering and improve the responsiveness of the rear suspension and diff. Installation is very simple, can be performed in under an hour, and is completely reversible.
By filling small voids in the four factory mounts as well as limiting vertical movement, the insert set eliminates the associated slop to ensure that you experience a more refined, connected driving experience, especially when driving at the limit. The billet aluminium parts will not wear over time and offer a lasting performance improvement.
Worried about noise? NVH is a measurement of how much noise, vibration, & harshness gets transmitted into a vehicle’s cabin. Based on feedback, MMR inserts transfer little to none NVH into the cabin. NVH is subjective, so some users may find NVH to be increased or decreased from our rating. If you are experiencing higher than quoted NVH with this product, please evaluate the installation to ensure the components are installed correctly.
The BMW F2x and F3x series use rubber diff mounts that deflect under load, causing the rear end to feel vague and loose, as well as leading to less-than-optimal suspension geometry and increased understeer. These precision-machined billet aluminium inserts are designed to fill voids in the factory diff mounts, and limit diff movement without sacrificing ride quality or introducing any perceivable additional noise, vibration, or harshness into the cabin. The result is a more refined, connected driving experience, as well as improved effectiveness of aftermarket rear sway bar upgrades and suspension components.
These inserts were tested extensively by MMR and independent BMW enthusiasts before release on multiple F2x and F3x vehicles. Our diff inserts fit diesel, petrol, manual and auto variants.

Well-told, fascinating history of an important event.
Format: Hardcover
There are many books available about the D-Day Invasion of World War II. But because so many people were involved, there are endless ways for the story to be told. In addition, for the same reason, authors have to pick and choose what information to share, there is simply too much to share in any one book. Plus, no two authors tell the story in the same way. Thus, there is a place for Hopkinson's book on the subject. And she's done a fabulous job in sharing the information in a way that works for adolescent readers.
The book starts with the experience of a young man flying over France as one of the thousands of paratroopers proceeding the sea-based invasion. This makes for a great beginning as it pulls the reader right into the story. Following a brief description of what D-Day was and how the U.S. Army was organized (helpful for those with little military or World War II background), Hopkinson goes back and tells the story of the major events that led up to the invasion itself. The book is divided up into 7 parts as follows: The Plan, The Gods of War, Night Into Day, Utah, Omaha, Aftermath: More than Courage, Quartermaster's Department. Each section includes important information related to the general plans and some of the individuals involved in creating those plans. As this book is written for American youth, it focuses on the two invasion sites that the Americans helped invade, the beaches code named Utah and Omaha. I especially appreciated the widespread use of quotes and experiences from individuals who were there. The story feels more real when one reads the words of an actual person. The inclusion of 'dispatches' and 'Reader's Invasion Briefings' helped create context in relation to specific issues that came up during the invasion.
All in all Hopkinson has created a compelling account of a day that changed the world forever. A day that young history buffs will want to know about. This is a book that would be easy to recommend to young readers who want a glimpse into the experiences of those involved in both the planning and executing of D-Day.

Read for yourself. Then book talk and get in the hands of students.
Format: Hardcover, Format: Hardcover
The kind of book you don’t want to put down. For sophisticated YA and adult readers. I thought I knew about D-Day, but as I began to read this book, I realized I had no idea what a complex operation this was--the covert planning and the freaking size of this plan. 13,000 U.S. paratroopers jumped out of planes. Some 57,000 stormed the beaches at Normandy. Others were brought in on "horsas" --airplane "gliders" made of balsa wood that were pulled by bigger planes and then let go to glide into enemy territory - with hundreds of men and equipment including jeeps aboard. Even though they'd planned and planned, the implementation was a debacle. Paratroopers and gliders landed off course. Amphibious vehicles, loaded with men, beached in the wrong spot or were hit by German weaponry and sank, leaving soldiers to drown or swim to shore, loaded down with 75 pounds of equipment. The Germans had lined the coast with explosives and were nested in to bunkers, ready to attack. The U.S. attempted to destroy some of this before men landed but were not successful. The men landing did not know this until they came upon well-fortified, heavily armored and waiting Germans (especially at Omaha Beach). It was a mess. And yet, they got a "toehold" onto the German occupied territory. A toehold that allowed the Allied forces to start moving against Hitler's army.
I’m writing all of this to say that Hopkinson expertly conveys the gravity and enormity of the situation. She does not pretend to know the feelings or thoughts of individuals involved in this experience. Instead she uses well-established facts and primary sources including many quotes from oral histories to tell the story of this day. Honestly, I finished this book thinking, “OMG” and feeling incredibly indebted to these soldiers and any other person who has served our country.
IN A CLASSROOM – My first thought is “Why do we still rely on textbooks in any kind of high school history class?” Book talk this. And then recruit a group of students to read, engage in student-led conversations, learn from additional sources, and then share their learning (and even their gratitude). Questions that might serve as a guide:
• “What made this endeavor enormous?” This kind of question includes the literal numbers, but also thinking critically about the emotional and mental weight of this plan on key individuals that Hopkinson alludes to and thinking beyond the text to the planning that Hopkinson does not describe, but that must have had to happen to get the troops ready.
• “How does Hopkinson weave complex details together in a way that makes the enormity of what happened accessible to the reader?” This could include a discussion of how she includes statistics, but also oral histories. What is the role of each of these types of details?
• “What does Hopkinson leave out?” or “What choices did Hopkinson clearly make about what to include and what not to include?” or “How does Hopkinson establish accuracy and authority throughout the text?”
IF YOU BOOK TALK THIS, a couple of tips:
• I would not take for granted the value of students previewing this text before reading, of students thinking through the design of the text (looking carefully at the table of contents) and the PURPOSE of special features (e.g., sidebars like “reader’s invasion briefing” and “dispatch”). This will help them navigate and make sense of the information. Even sophisticated readers could benefit from this.
• Also, for me, the narrative really picked up in Part 2 after Hopkinson develops the context for D-Day and describes initial planning. Keep an eye on (striving) readers during Part 1 or until you feel like they are on a roll. It wouldn't hurt to provide extra scaffolds like a current map of Europe, readers can reference as they move through the book or a chance to explore the topic (with video, etc) before they read.
• The technical language that Hopkinson includes early on related to service members' rank, division, etc. may bog some readers down. Do not let this deter them. You may need to think aloud in front of students about how you make sense of these terms as a reader and continue moving forward. This lightens up and becomes easier to navigate a little bit into the book.
The courage it took to face that day (and many others that we have asked service members to face since then) is stunning. As a reader of this book, YOU FEEL THIS. Towards the end of reading this book, I went to lunch with family and as we entered the restaurant, I saw a group of service members eating at a table nearby. I couldn't help it...I quietly paid for their lunch. I asked to be anonymous, but the wait staff gave me away. When the service members came over to say thank you and shake my hand, I nearly wept. I live in a freaking silo—I know no one serving in the military. This book strengthened by gratitude to anyone who has served our country. Thank you, Deborah Hopkinson.
