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.

Great read once the action gets going
Format: Kindle
I've never read anything by this author and picked up this series after seeing how many books were already released; very important to me nowadays as I keep hitting the end of other series I really enjoy and get stuck waiting for the author to complete writing the next installment. No such problem here as there are nearly a dozen installments already published. Plus, this first book was nearly 800 pages. It is the typical LitRPG where the storyline starts off with earth being forcefully and suddenly integrated into the "multiverse" and the MC having to learn all about the magic and leveling system in order to grow strong enough to find his family and defend himself. Thr plot might be standard but the writer throws in plenty of interesting bits like the primary invaders being demons and the MC choosing to wield an axe rather than the traditional sword. The only problem is that the MC is a bit of a whiner at first and nothjng much happens except a lot of grinding so stick with it. The action starts around the second half when he leaves his immediate surroundings full of low level mobs to engage the invaders. From there it only gets more interesting as he discovers other species whose worlds were merged with earth along with fellow humans. A leaderboard is also introduced tracking levels and wealth so we get a glimpse of other powerful humans besides the MC. The system controlling the multiverse promotes conflict and rewards the strong so the MC undergoes a total attitude change and goes from a desk jockey to near bloodthirsty in his quest for power. Purchasing the next book straightaway as I cant wait to read where the story heads. Would definitely recommend for fans of fantasy and particularly LitRPG.

Reads like a video game
Format: Paperback, Format: Paperback
Reads like a video game. Captivating, entertaining and hard to put down. If you like stories where your character becomes stronger and more skilled as he overcomes his enemies, gaining titles and unlocking quests, then this book is for you. I am honestly surprised at how much I enjoyed reading this book. I can’t wait for book 2 to arrive.

Entertaining, stats go burr, some annoying writing quirks
Format: Audiobook
This series is like following along your favorite video game MC. It has a decent amount of plot, although there occasionally is too much tangential action before resolving a plot. Don't expect amazing depth and you'll be pleasantly surprised by how mindlessly entertaining this story is. Yes, the male MC is so lucky that he survives everything even without a clever plan (ever) but at least the author kinda explains this with a high luck stat. It's basically an in-world explanation for plot armor, which I kinda respect in its audacity. That said, two complaints: 1) As a biologist, it's annoying to hear the myth that the "law of the jungle" is "only the strong survive" as the "way of nature" repeated over and over. This is an old fashioned and inaccurate understanding of evolution, which is primarily about survival of populations and certainly has selection at multiple levels (genes, individuals, familial groups, & populations). The idea that the system's goal of "strongest survive" in this novel producing anything like evolution is an annoying and persistent reminder of how poorly most people understand evolution. Fitness is defined by how well an organism matches its niche and how many offspring it has, not how many it kills or how strong it is. So if a cultivator in this novel becomes amazingly powerful and has zero kids, they would be a total unfit creature as defined by evolution. To add on, "law of the Jungle" understood as "every man for himself" is also an old misunderstanding of Kipling, who was actually making a point that even animals in nature follow some rules, after all "the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack". It has always baffled me how such a small scale collectivist phrase has been so thoroughly misunderstood my our individualistic culture. 2) The author has several annoying writing quirks, like needlessly using the word "itself" all the time. Similarly, adjectives are heavily repeated. Author favorites are "powerhouse" & "monster". It makes no sense that every culture would have the same slang and it's annoying to hear the same words so often. Might I suggest a thesaurus? It's fine if Ogras always says "monster" but everyone can't do that or it just seems like the author has limited vocab. On that note, too many things are described as near endless, limitless, etc. That is a nonsensical concept, which covers for not explaining something in measurements or metaphors. This is a common issue with authors who don't do math, but something "near" infinite, is actually infinitely far from infinite. Something is infinite or it's not. Again, lets find other terms like "vast" or "enormous." Or get even better and say something "stretched across a province/country/continent/planet/solar system/galaxy/etc". Those all provide size without saying something nonsensical. 2) Stats go burr to the point of confusion. We're supposed to track attribute points, Dao, race, core, skills, nodes, bloodline & bloodline skills. We need more charts at the beginning of each book. How about one showing how skills merged? And what's the difference between 50 and 100 strength. How about 1000 or 10,000? It'd be nice had even rough comparison to picking up some mass like 100 strength means picking up a car and 1,000 is picking up a mountain.

Outstanding litrpg novel
Format: Kindle
Sympathetic, proactive protagonist; good pacing; good dialog; good progression; believable secondary characters. The rules of the magic system are introduced gradually, so there isn’t a huge boring info dump at the beginning. The protagonist ends up overpowered compared to literally the entire human race, but it definitely feels like he earns it, and the threats he deals with scale to keep things challenging. The progression system is kind of complicated, but the protagonist ends up with a few strong abilities instead of dozens that are impossible to keep track of. The book is not a comedy by any means, but it does a good job of occasionally playing up the murder-hobo aspects of the protagonist for comedic effect. Story ends in kind of a weird spot, but I’m not complaining. The story blows past the first logical end point, dramatically shifts gears, and just keeps going. Then it ends a little abruptly at what feels like the 2/3rds mark of a second novel. You get more than one book’s worth of solid story though, so again, no complaints. All and all, I would judge this book to be somewhere between rare and epic quality.

MUST Read for any age.
Format: Paperback
I read this book as a sophomore in college for a unit on banned books. Knowing that there is a generation of students who won't get to read this book and think about/discuss the themes Lo presents is devastating. Despite the debates surrounding the book’s appropriateness for younger kids, I believe this book is EXACTLY what children need to be reading. Specifically, I think middle school-aged children could gain a lot of value in reading this book to help them understand sexuality, relationships with family and friends, and that not everything is as black and white as some people may believe. Lily and Kath’s relationship is written so beautifully, and as a reader, it felt real. Even though I would categorize this as a YA novel, anyone at any age can gain a lot from reading this. The story is captivating and real. Lily (the main character) doesn't get everything she wants, and while the ending is somewhat satisfactory, it leaves the reader wanting to know more, which I think has its pros and cons. Personally, I liked the general ending, but to be honest, I wanted to know more about what ended up happening regarding some of the storylines of the book. For example, Lily’s father had some issues regarding his immigrant status. We hear bits and pieces here and there, but we never really find out if/how it gets solved. Relationships like Lily and Tommy’s (a performer at the Telegraph Club) spark interesting conversations about power dynamics and where the line is between nurturing and overstepping. I understand parents, guardians, and teachers may be worried about “exposing” children to “difficult” content and discussing things like sexuality with young individuals. But in my opinion, books like this are the perfect way to lay the groundwork for those types of conversations. We are delivered messages and lessons through an interesting story with layers about what it is like to be a teenage girl in a World of uncertainty– something I think many can relate to. Please read. Please give to your children to read. Please don't let this book be erased.
