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.

Broke Within Moments
My two medium sized dogs played tug of war ONE time and it ripped in half. Not durable at all. Did not hold up well.

My dogs love fetching this toy, then fighting over who’s going to bring it back to me
Both of my miniature dachshunds took to this tug of war toy immediately after opening it. I liked the fact it didn’t smell terrible like most of the scented dog toys I’ve purchased in the past. Instead this one actually smells good, it’s sweet and fruity smelling. It’s extremely durable and very heavy duty. The only problem is that it’s pretty thick and heavy, especially for my small dogs. They still like playing fetch with it, then fighting over which one gets to bring it back to me. It really would have been the perfect fetching toy for them, if only it had been a little bit smaller and lighter. If you have larger sized dogs who enjoy playing fetch and tug a war, I’d recommend giving it a try.

Good Quality Toy, but Not a Hit with My Dogs
I am a bit unsure about this toy. Unfortunately, my dogs do not seem to enjoy it very much. I thought the blueberry apple scent would make it more appealing, but they tend to lose interest almost as quickly as they start playing with it. I was hoping this would be something we could use for games like tug of war, but it just has not held their attention. That said, I may just have picky dogs, so this could be a different experience for others. The reason I gave it two stars instead of one is because the quality is actually quite nice. It feels well made and has a good overall design. However, I would be a little cautious giving it to aggressive chewers, as it seems a bit on the softer side. For dogs that are more gentle with their toys, it would likely be a better fit. The size is also great, and it has a lot of potential. It just has not gotten much use in our house, likely due to my dogs not being fans of the flavor. Overall, if you have picky pups like mine, this may not be the best choice. But for less selective or gentler dogs, it could still be a solid option

Stretchy, but Smaller & Softer Than Expected; Berry Fragrance Dominates; May be Best 4 Puppies
I was directed to read guidelines that were on the internet, prior to use. I was not expecting that and that was a big turn-off. Basically, it's all about liability, this product has the possibility of being torn apart and I am basically warned that if a piece is chewed off, that's bigger than a grain of rice, to toss, this. I was repeatedly reminded, again and again, and again that pet safety was my responsibility. Yeah, I know that. All these suggestions and warnings should have been made clearer in the listing. Is this built to flex? Yes. Does it bend? Yes. Does it stretch? Yes. Is this rugged? That's open to debate, based on the users, for a puppy, to some degree, but their teeth are very sharp. Is this soft on teeth? I don't disagree. Does this have a durable design? Depends on the user. Floats in water? I do not doubt it. Does this have an enticing scent? For a human, yes, for a pet? Depends if your pet loves berries. This is no pigs ear/bone, so, chewing is not a natural draw that I saw, which I think may be better, because this is soft and easier to tear to pieces than expected. To motivate the first time, I found it best to initiate the tug of war, but this is smaller than I envisioned too, causing me to have to bend considerably to participate. A tennis ball in a tube sock is longer. A two-dog tug of war works best with this. Nevertheless, it's a better toy than teaching pooch to have a battle using clothing, avoiding future attractions to my socks. There is some flexibility to this. Durability is an issue. I think this would have been more interesting if it had been made out of rawhide. It does have a comfortable grip, for a human, but the toy pays a price for that with what I would consider fragility. The berry fragrance dominates, it's nice for a human, but sorry, it ain't no bacon aroma. It's like a thick heavy rubber hose. Value? In hindsight, I just do not see the value I was expecting. I mean really, a grain of rice warning not to use. Durability at issue in my eyes. Country of origin? Vietnam. Is this perfect? Not in my opinion. Rating? A strong three (3) stars at best in my eyes. This is not for a tough chewer. I have to constantly monitor its condition. It does succeed as a tug toy, but it has more limitations that I was expecting. I hope my thoughts added a bit of information.
