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.

Considered to be the best science fiction novel ever written.
Format: Mass Market Paperback
This book is often considered to be the best science fiction novel ever written and for good reason. _Dune_ is a 1960s-era science fiction novel, published on the cusp of the Golden Age and the New Wave. Science Fiction of the time was in a transitional period influenced by the periodical _Galaxy_. SF at the time emphasized what some would call soft science fiction, a genre dealing with psychology, sociology, and sociopolitical commentary, with the bonus of one or more unique original ideas and a Sense of Wonder. Within these domains, _Dune_ hits every note a book of its genre could possibly hit and does so brilliantly. This is not anything like what passes for science fiction today, as the genre has been heavily-influenced by the Modernist movement and is now characterized by meandering fiction with long atmospheric narrative descriptions and no idea content other than politically-correct gender diversity, as is often found in a Gardner Dozois Year's Best anthology. This novel seems more nuanced and cogent to me today as an adult than it did when I first read it as a teen. The explorations of preternatural consciousness, mind control, economics, religion, and political intrigue are fascinating. But _Dune_ was also revolutionary in its use of what was then called Ecology (now called Environmental Science) as a hard science. This book is a high mark in the achievement of hard-science worldbuilding. After all these years it is still the most well-thought out and well-fleshed out worldview in the entire SF canon. Its complex, logical worldbuilding is presented in what was the then-prominent Science Fiction protocol of revealing the world little by little through contextual clues rather than inserting infodumps of description. As such it takes more work to read than a more modern book with infodumps. Readers who find the book boring aren't reading it with Science Fiction reading protocols and apparently most of them are too callow to resonate with some the book's political, economic, and sociocultural commentary. The genre was about ideas, not literary modernism, so you will not find the book filled with metaphors and literary allusions such as one might find in a Creative Writing MFA's workshopped short story, although Paul's story is clearly the Hero's Journey and he is obviously a Messiah figure as well as a military/political leader. The characters may not be as well-rounded as in a Dostoevsky novel but in case you missed it, the main character isn't really Paul. The main character is the planet Arrakis. Read this book with that in mind and you'll be amazed. For those expecting a Hollywood superhero comic-book style movie with action scenes and high-definition special effects, there is some of that in here too, but that is not the main point. This is a Frank Herbert novel of ideas, not a David Lynch film of striking visuals.

Good to use every night...I do.
If you suffer from dry mouth during the night, these are the perfect solution. I had tried rinses - they don't last. Sprays - they don't last. lozenges - don't last. Other tablets, only last a few hours. I can get about 8 hours relief with these. Contrary to other reviews, you do not suck on them like a lozenge...they won't last at all if you do it that way. Read the directions. They "adhere" to your back molars...don't drink or eat after putting them in...as both will either dislodge or reduce the effectiveness. However, when I don't use these, my mouth is miserable and so dry. These provide enough moisture throughout the night. The flavors aren't too bad. I've used the mint (not may favorite because I'm not a fan of mint flavor), orange and berry. I wish they had other flavors (cinnamon, licorice), but till then, I'll use these probably forever.

Really helpful for dry mouth.
Scent Name: Berry, Size: 100 Count
These really work. I wear a CPAP and my mouth was so dry I was waking up with my tongue stuck to the roof of my mouth. They stick well so no worry of swallowing it during the night. I like the berry flavor.
