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.

I am so spoiled and I hope you will be too!

Great product! So far I have purchased six sets… one for me and five others for gifts. And I only give gifts that are helpful. I like that the grinders are adjustable. I charged them when I think they need it. They have never stopped where I had to charge either of them. I feel so spoiled. Wish everyone could have these. I are very dependable. I’m sure I will be buying more in the future. Thank you for making a wonderful product. I, as well as others, are enjoying them.

Love these. Charge quickly. Love the red light while charging that changes to white when it is full. Love the rack and brush for cleaning that comes with it. Works as it should.

Very nice grinders
Color: White&Black, Color: White&Black
Still going strong after six months of use. The product is sturdy and easy to hold, the adjustable grinding coarseness is an added bonus and make the grinders easy to use. If you are looking for cordless rechargeable grinders this is the best value for your money. The base is a little hard to clean but a quick brush removes all of the excess grinds. They stay fully charged on the stand and I have never had an issue with them being out of battery.

A small upgrade that transformed my kitchen: practical, elegant, and surprisingly satisfying
Color: Black
I bought these grinders while reorganizing my kitchen and realized something simple: I use salt and pepper every single day, but I always had messy, inconvenient containers. I wanted something functional but also nice-looking, so I chose this set somewhat urgently… and it turned out to be a great decision. From the very first use, I loved them. The one-hand operation makes such a difference, especially when you’re cooking and your other hand is busy. Just press a button and it works effortlessly. One thing that really surprised me is the adjustable grind settings. I didn’t think I’d use that feature much, but now I actually notice the difference depending on what I’m cooking. The grind is consistent, and it really helps preserve the flavor of the spices. The charging base is another big plus. Not having to deal with batteries is such a relief, and they charge pretty quickly. I just keep them on the base, and they’re always ready to go. I also really like the LED light. It might seem like a small detail, but it’s actually very helpful when you want to control exactly how much seasoning you’re adding. And honestly, they also look great. They add a modern, organized touch to my kitchen, which I appreciate more than I expected. In the end, I bought them just to get more organized… and they became one of those everyday items you actually enjoy using. I’m really happy with this purchase and would definitely recommend them.
