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.

The Toy That Tires Out Your Dog So You Don’t Have To!
Color: Classic Blue, Color: Classic Blue
After trying a different interactive ball previously, I can confidently say this one is built much better. The construction feels more durable, and most importantly, it has held up well against my dog's enthusiastic chewing and chasing. Many interactive toys claim to be tough, but this one has actually survived extended play sessions without being torn apart. The charging design is simple and well thought out. The ball twists apart easily to reveal the USB-C charging port, making recharging quick and convenient. Once charged, you simply twist the halves back together, press the power button, and it's ready to go. I appreciate that there are no complicated steps or special charging accessories required. What really stands out is how engaging the toy is. The unpredictable movement keeps my dog interested and encourages plenty of exercise and mental stimulation. Instead of losing interest after a few minutes, my dog continued chasing, pawing, and interacting with the ball until he was genuinely worn out. For pet owners looking for a way to help burn off excess energy, this toy definitely does the job. One minor issue I noticed is that on a couple of occasions, my dog was able to accidentally turn the toy off while carrying it in his mouth. It wasn't a frequent problem, but it did happen enough to be worth mentioning. Fortunately, turning it back on is quick and easy. Overall, this has been one of the better interactive dog toys I've tested. It's durable, easy to charge, keeps dogs engaged, and provides the kind of activity that leaves them happily exhausted afterward. If your dog enjoys chasing moving toys and you want something sturdier than many of the alternatives on the market, this is a solid choice.

Great Entertainment, Short Battery Life
Color: Classic Blue
This is the first interactive ball I've found that my dog hasn't managed to destroy, which is impressive on its own. The ball keeps him entertained for long periods, and he loves chasing, nudging, and following it around the house. The material feels durable and has held up well to regular play. The one button operation is convenient, and the ball is easy to recharge and clean. My biggest complaint is the battery life. On a full charge, it only seems to run for about 10 minutes before needing to be recharged again. Because of that, I find myself charging it frequently. Even with the shorter runtime, it's been one of the more engaging and durable interactive toys we've tried. Overall, a fun and sturdy toy that keeps dogs occupied, but be prepared for frequent charging.

Fun Dog Toy
Color: Classic Blue
This toy has been a lot of fun for our dogs. One of my dogs absolutely loves balls and is perfectly content to just carry this around in his mouth. The outer shell feels like a firm foam material. It is durable while still being lightweight enough for the dogs to enjoy. The ball screws together, but it is designed well enough that you are not constantly worried about it coming apart. You have to intentionally press and twist it to open it, so normal dog play has not caused any issues. Inside is the motorized component, which is easy to turn on and recharge. It offers a few different vibration modes, which keeps things interesting. The reactions from our dogs have been hilarious. One dog is convinced the ball might be plotting against him and keeps a suspicious distance. Another dog loves it so much that he holds it in his mouth while it vibrates, making his entire head shake. Our third dog plays with it exactly as intended, chasing it around and interacting with it normally. The motor has enough power to make the ball bounce, roll, and move unpredictably across the floor, which keeps the dogs engaged. It has been a great addition to our toy collection and provides a different kind of enrichment than a standard ball. Overall, the dogs really enjoy it.

A fun toy
Color: Classic Blue
Our Malamute loves this ball. He likes to carry it around with him and let it will out of his grasp and pick it back up. The outer ball it tough and durable, and so far it has held up well during play. It does bounces more than rolls I expected a little more movement across the floor in a more rolling fashion... like those weasel balls from the 90s, but tends to hop and bounce in place. It does works best on hard floor where it has enough contact to move around and keep the dog engaged. To charge you have to unscrew the ball in half to access the motor unit, and there is grease on the motor, so be careful when opening it and handling the internal piece. It is not difficult, but it is a little more complicated than a simple plug-in charging port. The button on is also super hard to press. I you have to really squeeze it and even use a tool to turn it on. It has 2 modes though it is so hard to press I am not sure which mode I actually turn on. It so far has been a fun toy for our young dog and has lasted our extreme chewer (only supervised play) I would recommend if it went on sale.

Works well on hardwood, and my dog is just a coward
Color: Classic Blue
This ball works really well on hardwood floors, rolling and moving around just like it's supposed to, though it struggles on carpet where the resistance seems to bog it down. I expected my dog to be thrilled by it, but instead he was afraid of the thing. In fairness, he's a big scaredy-cat by nature, so that says more about him than the toy. The ball itself feels very tough and well made. If he would actually work up the courage to chew on it, I suspect it would hold up extremely well, and I don't think he'd be able to pop it open on his own either. So it's a solid, durable toy that's earned my confidence, even if it hasn't yet earned my dog's.
