Porterfield R4

Porterfield R4 Carbon Kevlar based brake pads were fully designed for heavy-duty extreme motorsports use. Its one of the the few true motorsports competition pads available on the market today. The carbon based semi metallic R4 brake material allows the brake pad to absorb huge amounts of heat and dissipate it quickly and evenly over time. The Carbon-Kevlar material also allows the brake pad to heat up to operating temperature right away so little pad warmup is required for optimal operating condition. This compound also requires very little bed-in so that one is able to change out the pads and almost immediately able use them to their full potential.

R4 series provides high initial bite for immediate brake response while yielding extremely consistent modulation and predictability. This is great for all road courses, oval track, rally, vintage racing, autocross, club events, and professional driving events. This is one of the best motorsports pads we have used. Available for many applications, so please contact us if you do not see one for your car.

Porterfield R4-1

The R4-1 Vintage Full Race Compound was developed using knowledge testing in the vintage racing community. Optimum uses for the R4-1, under conditions where very high friction is needed with minimal warm up time and in applications where there is difficulty in maintaining sufficient heat with conventional race pad compounds. Widely used on vintage GT and formula cars the R4-1 is also gaining popularity in off-road and rally-cross classes. Great modulation, consistent pedal feedback and rotor friendly at all temperatures as with all the other Porterfield Carbon Kevlar compounds.

Porterfield R4-E

The R4-E Endurance Race Compound is a carbon kevlar compound made to last a bit longer than the original R-4 compound. The R4-E compound is designed to endure higher prolonged temperature and still has pad life as long or longer than Porterfield R-4 do. This pad is great for club enduro events and applications where temperatures are at their maximum.

Porterfield R4-S

Porterfield R4-S high performance street and autocross brake pads are great for heavy-duty street and light track applications. Compound is perfect for everyday use while still keeping the highly capable track ready performance. The R4-S features a high friction level that will increase your stopping power with minimal pedal effort.

The R4-S series pads are VERY VERY rotor friendly and yield very low levels of dust; levels are far below OEM equipment or any other high performance brake pads. Your car will stop better and your wheels will stay cleaner longer. Good for autocross, rallies, driving school, and of course daily driving with a little extra stopping power. R4-S pads are available for virtually all vehicles sold in the US and custom R4-S pad sizes for competition style calipers are also available.

This is one of the very best all around street/strip brake pads available at a great price.

Interesting and important read, but less objective than I expected.
Format: Hardcover
I feel this book has received higher review ratings than it probably deserves. Yet, it's still an overall good read and it discusses an important societal issue of U.S. history. This review will include both positive and negative feedback of this book. The author, Ibram Kendi, has done a great job at making this book accessible to readers. It's not overly infused with academic jargon. The chapters are also quite short, which makes it easier to read. The substance of the book is pretty informative too. Kendi's frequent usage of quotes really exposes the racist attitudes and ideas that were (and still are) present in American society. Although this book contains an abundance historical quotes, many of them lack sufficient explanation and context. As a student of history, I appreciate deeper, rounded discussions of historical figures. I felt that Kendi mostly includes short bits of statements from historical figures, then hastily shows how those statements equal racism in the person being discussed. I guess Kendi's style is OK. It just doesn't quite feel dedicated to historians craft. Another, less important critique is about the book title's usage of the term "Definitive." I'm surprised that this work was labeled as definitive. To be definitive, it would need to include racial histories of ALL ethnic/racial groups throughout both the American colonial and U.S. eras. Alternatively, this book's title may have been more appropriate as "The Definitive History of Racist Ideas Towards Peoples of sub-Sarahan African Descent in America." Overall, I'm glad I purchased and read this book. It boldly explains certain sides of history that much of our society has missed. I did not grow up in a "racist" household. Yet, this book helped me reflect on my own attitudes, which have been influenced by racist ideas to some degree. I hope others (especially other Americans) can read this book with an open heart and mind.

The REAL American History
Bearing 511 pages of text supported by nearly 70 pages of footnotes, Ibram X. Kendi’s Stamped From the Beginning (Bold Type Books, 2017) is, for me, not an “alternative” American history but THE American history. Kendi, founding director of the Boston University Center for Antiracism Research, makes a convincing argument—which he emphasizes in his other books and public speaking—that, contrary to conventional assumptions, racist policies drive racist thinking and not the other way around. And, Kendi adds, it’s economic, political, or cultural self interests that give birth to such policies and motivate their rejection when new circumstances demand it. In making his case, Kendi patiently and passionately traces the development, implementation, and adaptations of three racial dynamics across the history of the U.S.: 1. Segregation: Blaming Black people themselves for racial disparities, and therefore denying them the privileges 2. enjoyed by white Americans 3. Assimilation: Blaming Black people and racial discrimination for racial disparities, and demanding Black people change their behavior in order to experience less racism Antiracism: Pointing to racial discrimination and policies while defending Black people’s right to be themselves In addition, Kendi structures this narrative across five lengthy sections, each centered on the impact of a specific, influential “tour guide” and their contemporaries: 1. Cotton Mather, early America’s greatest preacher and intellectual, and a staunch promoter of racist policies and ideas 2. Thomas Jefferson, primary author of the Declaration of Independence, and America’s first Secretary of State, second Vice President, and third President, who held contradictory views amid incongruous political and personal actions 3. William Lloyd Garrison, an influential publisher who opposed slavery but embraced assimilationist ideas 4. W. E. B. DuBois, a towering Black intellectual who gradually shifted from assimilation to antiracism 5. Angela Davis, one of the best known Black scholars and antiracist activists still alive today When you’re done reading Stamped From the Beginning, you’ve gained a new framework for noticing and examining race and its interrelated justice issues. Current racial events take on a richer meaning, with their nuances and complexities more tangible than before. Other books on racial justice help to reinforce this framework and further develop a reader’s embryonic skills for noticing racism within themselves, others, policies, and systems—and doing something about it. To grow increasingly fluent in Black history is to awaken from the slumber of an incomplete, biased, and often false American narrative that’s been drilled into most of our minds since we were young children. Since racism remains very much alive today, waking up is crucial and, from my experience, invigorating and teeming with possibilities for a more purposeful life.

This should be required reading for everyone..
Stamped From the Beginning discusses the history of racism and racist ideas in America. Kendi focuses on five main people who have made the biggest impact on racism and anti-racism in our history: Puritan minister Cotton Mather, Thomas Jefferson, abolitionist William Lloyd Garrison, W.E.B. Du Bois, and legendary activist Angela Davis. “When men oppress their fellow-men, the oppressor ever finds, in the character of the oppressed, a full justification for his oppression.” Douglass, amazingly, summed up the history of racist ideas in a single sentence.” - (Fredrick Douglass) This was an incredibly powerful and educational book. I knew going into this book that the United States education system has failed at teaching the history of slavery, emancipation, Jim Crow, and the continued struggle. But it still amazed me at how much it doesn’t teach. With every single chapter I learned new things that should have been taught to me in school. While this is a very large book filled with history, it was an easy read. Normally I would have read this book in a few days but instead I stretched it out over a month and a half. I read, reflected, took notes, did more research and I still know that I have a lot to learn. My book is now covered in sticky notes and I know I will be rereading this in the future because I know I missed stuff. “That is what it truly means to think as an antiracist: to think there is nothing wrong with Black people, to think that racial groups are equal. There are lazy and unwise and harmful individuals of African ancestry. There are lazy and unwise and harmful individuals of European ancestry. There are industrious and wise and harmless individuals of European ancestry. There are industrious and wise and harmless individuals of African ancestry. But no racial group has ever had a monopoly on any type of human trait or gene—not now, not ever.” This book changed the way I viewed the history of the United States. So much of this history has been glossed over by the education system, and other history books. This book should be required reading for everyone especially since the education system won’t teach us the true history of the United States. All I can say is, READ THIS BOOK!
