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.

A Fluoride‑Free Toothpaste the Whole Family Honestly Loves
Size: 4 Ounce (Pack of 3), Set name: E. Orange Cream, Watermelon Mint, Strawberry Mango
We’ve been using Boka Fluoride Free Toothpaste with Nano‑Hydroxyapatite for a while now, and it has easily become a staple in our household. Finding a toothpaste that is both clean and effective and something my daughter actually enjoys using has always been a challenge, but this one truly checks every box. First, the flavors deserve special mention. We’ve tried Orange Cream and Watermelon Mint, and my daughter absolutely loves both. There’s no struggle at brushing time anymore, no complaints, no resistance. She actually looks forward to brushing her teeth, which as any parent knows, is a huge win. The flavors are fun but not overpowering, and they don’t have that harsh or medicinal taste found in many toothpastes, especially “kid-friendly” ones. From a parent’s perspective, what really sold us is the fact that Boka is fluoride‑free and made with clean ingredients. We love knowing that we’re not exposing her to unnecessary chemicals while still supporting good oral hygiene. The inclusion of nano‑hydroxyapatite gives us peace of mind as well, it feels like a modern, thoughtful alternative that aligns with what we want for our family. The toothpaste feels gentle, non‑gritty, and leaves mouths feeling smooth and clean without dryness or irritation. The texture is another pleasant surprise. It’s creamy and smooth, easy to spread on the toothbrush, and doesn’t foam excessively. Both flavors leave a fresh, clean feeling afterward without any lingering bitterness. Even as adults, we genuinely enjoy using it, which says a lot, we often find ourselves reaching for it instead of our usual toothpaste. Overall, Boka Toothpaste has made brushing easier, more enjoyable, and more reassuring for our family. My daughter loves every flavor we’ve tried, and we love knowing we’re using a product that’s clean and fluoride‑free without compromising quality. If you’re looking for a toothpaste that works for both kids and adults and one that finally ends brushing battles,, I can’t recommend this one enough.

Toddler Approved!
Size: 4 Ounce (Pack of 1), Set name: A. Strawberry Mango
I never thought I’d describe toothpaste as “fun,” but here we are... I bought this Boka strawberry mango flavor for my toddler — I figured he would enjoy this over a mint flavor because what kid enjoys a harsh, burning feeling? It smells fruity and tastes like a smoothie. We are still practicing brushing but this toothpaste helps encourage the importance of daily teeth maintenance. Also, I love that it’s fluoride-free and I am not worried if it's swallowed. It is pricier than I would prefer, but it has lasted so long that I've came to terms that it's worth the cost.

Made in America nano-hydroxyapatite Toothpaste that's Well Worth Buying.
Size: 4 Ounce (Pack of 3), Set name: E. Orange Cream, Watermelon Mint, Strawberry Mango
This review is pretty much the same as the one I wrote for the Boka Coco Ginger. Boka Toothpaste is just that good. I've been using the Japanese brand Apagard Premio toothpaste for a couple of years now and recently I noticed this Boka toothpaste while looking for alternatives that wold be less costly. I've been using this toothpaste since the end of May, 2025. I wish they would sell it in larger tubes. Boka Toothpaste is very mild and makes brushing your teeth better. It doesn't have that harsh mint flavor which with most toothpastes feels like it's burning your mouth. It comes in multiple flavors and when you're done brushing your teeth, there is no need to rinse your mouth as it is a safe toothpaste to use. After having used it for a few days, I decided that I will keep using the Boka brand from now on. I just wish that most stores would carry this toothpaste instead pf selling all those major brands which are full of fluoride. Did a bit of research and found that Boka Toothpaste has the same percentage of nano-hydroxyapatite as Apagard Premio which is 10%. So that means that Boka Toothpaste is just as good if not better. No Fluoride No Harsh burning Mint Flavor Safe to shallow Multiple flavors 10% nano-hydroxyapatite Keeps your teeth Strong And one thing I've noticed is nano-hydroxyapatite makes your teeth less sensitive by rebuilding your tooth enamel I ordered four flavors, Watermelon Mint, Strawberry Mango, Orange Cream and Coco Ginger. So far, I've tried the Coco Ginger and I was surprised at how mild it was and it didn't have the sharp taste that ginger usually has. It is good and I enjoy it. I also tried the Orange Cream which was good. I'm looking forward to trying the other flavors. The Orange Cream I'm sure my wife will like if I can get her to try it. But she can be very stubborn at times. I see there are some other flavors which I intend to try such as the Cinnamint, Cucumber Dill, Lemon Lavender and Strawberry Basil. Not sure if I should try the Ela Mint as I don't know how strong or mild the mint will be. I'm sure that if places such as Walmart brick & mortar stores sold this toothpaste, that it would sell really well.

Favorite toddler toothpaste
Size: 4 Ounce (Pack of 1), Set name: A. Strawberry Mango
I bought this for my 18month old who has all his teeth already. It works great. The smell is pleasant, the taste isn’t harsh, and the texture isn’t as thick as most toothpastes - perfect for a toddler. I’ve been using this for a couple of months now and have not noticed any irritation. He enjoys it about as much as any 18 month will, ha! It’s just as effective as fluorinated toothpaste. You get what you pay for. It’s a big tube!

Good flavor, not as full of tubes as I expected.
Size: 4 Ounce (Pack of 2), Set name: G. Orange Cream, Ela Mint
My kids have LOVED brushing their teeth with this. They had been fighting to let us brush for a while, so it was nice to find something they liked. My husband and I have been using the mint flavor, and it’s been good as well. We like the ingredients, and the texture is nice. The tubes both felt like they could have fit more, so I took off a star for size/value.
