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 for newcomers to Godot
Format: Paperback
Excellent book for beginners with Godot. It will however require some previous programing knowledge this book isn't so much a teaching you to code book instead its an explanation of the Godot software.

Godot, a Beautiful Engine that is Great for any Budding Developer
Format: Kindle
My background: I am a professional VBA programmer that has used Unity3D as a hobby engine off and on for years. Until Godot, I had zero experience with Python. GDScript (Python-based) is easy enough to pick up once you understand its syntax IF you know other languages. The Review: The Kindle version is great. I have been following along quite easily. So far, I've kept up with what the book has told me to do and have learned quite a lot about about game development in general. Here's the reason for the three star review: I cannot find where to download the assets they talk about in Hour 5. If it came on a disc for the physical copies, that's wonderful! Great for them. That does nothing for the Kindle version. I couldn't find anywhere in the book that said "got to this website to download the files for the projects you'll be doing in this book. So, I came here, where I bought the book from, looking for a FAQ or something that may lead me to where I can download the assets manually. I googled what I thought would find the files with nothing that I could do about it. So, now I am stuck if I want to continue the book and use the assets they're using because there's nowhere clearly spelled out where to get the assets they've cited, page 73, "First, locate the “sprites” folder, which contains all the needed Sprites for this hour, in the accompanying “Godot-Hour 5” folder and copy it into your Godot project folder using your OS’s file explorer". Good luck in your game development journeys! Update 1: Got in touch with the publisher, they told me to get in touch with Amazon after trying to get the assets through their website, which proved to be unsuccessful. Update 2: Spoke with Amazon, they said that they are merely the store, that they can only provide what is given to them to provide. Please contact the publisher. Update 3: Contacted the publisher again about the issue citing what Amazon said. The publisher said they couldn't do anything about it that it is on "Kindle" to rectify. Update 4: Ultimately, I returned the book. I was enjoying the book very much until this issue happened. I am going to rate this book a 1-star because of the fiasco that has to do with the assets that they mentioned in the "Hour 5" chapter that I never got access to. I hope that this helps anyone make a decision as to whether or not to purchase for themselves. Update 5: I downgraded my review from 3-star to 1 star. Update 6: I continued to press this situation with the publisher of the book. Come to find out, Pearson (cited as the publisher) is not the publisher, per-say but InformIT is. I was incorrect about something that I said earlier about there not being anything in the book for the assets download. I found it after digging some more. There is a page that states that you should go to informit.com/register and use a specific ISBN (the book lists it) to register the book for additional content, updates and what-not. I have done so. So, I dug around on the InformIT website looking for the content, hoping that in this whole debacle, I am just dumb. After a lengthy conversation with an associate from InformIT, the files are, infact, not available. The associate has forwarded my problem higher-up and I should expect an answer in 24-48 hours. I will update this review again once I get an answer. Again, I do not blame Amazon. I blame the publisher(s), Pearson and InformIT for this. Also, let it be known that I have purchased the physical copy of the book despite the problems I am having in hopes that I will still get good information from the book overall. Update 7: It's been a while. I thought that my last update was posted. Though, it seems that it was not. Here's the update: After a few back-and-forth with the publisher that ultimately was responsible for the book, they gave me a link to the assets. Since I cannot paste the link, I will say that you can google the assets yourself. If you're interested in them, please google "github godot 24 hours". My first query response was the exact link needed. I sincerely hope that everything that I've stated here helps. I am going to start following along in the book again since I have the assets needed now. I am upgrading my review back to a three-star until I can fully assess the book. I think that it is asinine that I had to jump through the hoops that I did jump through to get the assets that were needed in order to follow along exactly. I don’t have time to be an asset artist on top of a programmer. I also don’t have too much money to buy assets. Thus, having the assets that were necessary to complete the projects as written would have been nice.

For Total Beginners in Godot, But I Still Learned a Few Tricks
Format: Kindle
Godot from Zero to Proficiency is a short book that aims to get total beginners up to speed with the Godot engine. The author does not cover programming (this is saved for the second book in the series) but rather just shows how to do basic things using the editor buttons. Even though I have been using Godot for over a year, I still learned a few interesting tricks, so that made the read worth it for me. However, the book is clearly designed for total beginners. Most of the topics are so basic you could probably figure them out just clicking buttons in the interface, but if you are new to Godot this might be a helpful light introduction. As mentioned before, the book is not super in depth. It covers how to install the engine, navigating the interface, placing objects and modifying them, adding lights, exporting your game, and importing library assets. Very basic stuff. The artwork used in the book is not great, it definitely has a “programmer art” look to it, but it suffices to show you how things work. Honestly the book only scratches the surface, but if you’ve never used Godot before and are a beginner to game development it might be okay. If you have any experience, I would say look elsewhere, though I did learn a few tricks that made it worthwhile (and the price of the Kindle version was very reasonable). So overall I would say this is one of the weaker Godot books out there, since it only covers a small portion of the engine. It does have good instructions on the basics of the editor, that was nice, but it doesn’t even show any programming. If you are a beginner and read this book, I think you’ll be more comfortable, but still not at a place to start making your game. There is a second part of this series (I will read that next) so that may help fill in the gaps. But considering the reasonable price (on the Kindle) and also that the book only took about 30 minutes to read, I can’t complain.

Pretty solid introduction to GoDot as a complete beginner.
Format: Paperback
I'm not new to programming but I am new to GoDot. I started this book as a complete beginner to GoDot with no other knowledge. This book gives a pretty solid foundation to start with. I'm sure most of this is probably online at this point but it was nice to have something I could easily view offline and come back to. I took a star off as some parts of the edition I have has minor typos. Nothing that completely derailed my studies but something I had to recheck.

A Good Starting Point
Format: Paperback
I have experience with 3D modeling software and am an experienced programmer. It took me two days to get through the book, and I learned quite a bit about Godot. It would likely take someone completely new to this sort of software quite a bit longer. You could certainly dig up all the information in this book online, but this book walks you through the basics step-by-step and I recommend it as a starting point that isn't going to overwhelm you. I have just ordered the rest of the books in the series.
