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.

Cute little bug that does its job. Good value.
Size: 17" (2 x 4.0Ah)
Not bad for the price. Pretty easy to set up (only user stupidity gave me any issues). Worked well for my first cut. Lasted about 32 minutes. I'm gonna give the batteries a more significant charge and try again, though I did charge for over 12 hours and the lights were solid green. So not sure what's going on there. I don't understand how "user technique" applies here, though I did hit a lot of hidden sticks. Could have burned through more energy? Idk. But it did handle those sticks like a champ! I made sure to get all the big ones out of the way, but there were some small ones and it just ran em right over good as any gas mower. I would probably play pickup sticks a little longer beforehand next time, but I was a little pressed for energy today. Anyways, irrespective of the actual function of the machine, I prefer this dramatically over either wider or self-propelled models. Self-propulsion can be very annoying when trying to get around difficult terrain or obstacles. I also enjoy the exercise! The small form factor is very nice again for obstacles or weaving between objects. It also is nice and light and easy to push. After 30+ minutes of mowing I'm not even remotely sore. I also enjoyed just getting to smell the fresh cut grass rather than belching gas smoke! I'm looking forward to low maintenance on this lil guy. The blades seem pretty well made, and I will be keeping an eye on them for wear and tear. I had a nice day outside in perfect weather with this little bug, and can recommend it if you're specifically looking for a smaller mower that lasts 30-40 mins on a charge and can deal with a push mower.

Powerful, easy to use, and perfect for small yards.
Size: 17" (2 x 4.0Ah)
I was pleasantly surprised at just how well this mower cuts and handles! Years ago I bought a Greenworks electric mower and loved it, but it was a pain trying to pull the cord around. When I happened upon this mower, I thought I'd give it a try and am so glad I did! The box is heavy, but this 63 year old woman managed to get it inside the garage and out of the box. The handle is simple to install, as is the grass catcher. The height adjustment mechanism is one of the easiest I've ever used. Once the batteries were fully charged, (they do take a few hours), I had my small front yard mowed in less than fifteen minutes. It isn't as quiet as an electric, but it's not as loud as a gas powered and there are NO fumes. I used the grass catcher and when I emptied it I found that the grass mulched was almost like saw dust! I hope this machine lasts a long time!

Good little mower but not perfect
Size: 17" (2 x 4.0Ah), Size: 17" (2 x 4.0Ah)
Decent little mower. Purchased it so I could take the sketchyness out of my front yard using my rider with the slope I have. Did a good job cutting the grass and is super quiet and very light weight. I've added some pictures of the handle extended and folded down next to my other tools for some size comparison as well. Stores well too. Grey button circled is how you adjust the deck height. Press and lift or push while holding the button down until you get your desired height and release. Super easy. Battery life is ok. I wouldn't be able to do my entire yard front and back on one charge. Batteries were almost dead after what felt like 25 minutes of use but my grass is rather thick so theres that. It did what I wanted it to do on one charge so I'm happy although it won't do a full yard front and back. You would need an extra set of batteries for that. Little assembly required. You have to put the grab bar on and install the mulch plug or bag yourself and charge the batteries before use and you're good to go. Not a super strong mower but thats to be expected at the price point. Strong enough to get the job done though. Some of the thicker parts I had to do two passes to get a good cut and it stalled out on me once. Thats ok though because I have the mulch plug installed and mulching boggs down any mower. 4 stars because there isn't a good carry handle to use when it is folded up that I could find. You kind of have to manhandle the thing into where you want once its folded up. Opened the box when it got delivered to find the batteries and charger just tossed in by the factory. Was a bit frustrated seeing that stuff just banging around in the box. Pros Quiet, light weight, stores great decently strong Cons No go handle when folded up, packaging Would I recommend? Yes. Good cheap alternative if you have a very small yard or are needing something to edge with or need to get to a hard spot that a rider is not the best for. Plus you don't have to worry about a cheap gas mower blowing your arm out with 10 minutes of pull starting.

Nice toy.
Size: 17" (2 x 4.0Ah)
This is definitely my favorite lawn mower I ever had. It is super light weight and very quiet. It is easy to put in my shed because I can lift it with one hand. I do not need to worry about spilling gas or oil. The arms fold easily. I feel like I am pushing one of those little baby lawn mowers with the bubbles. If you have a bigger lawn, I would use a bigger size than 17 inch. It is perfect for my yard but takes a little more passes. We will see how long the batteries last. So far, I used it a few times and I can do the front and back in one charge.

Thoroughly disappointed
Size: 17" (2 x 4.0Ah)
This is my third green Works cordless electric lawnmower. I am thoroughly disappointed in this one. They have changed the mechanism for lowering & raising the wheel height. Previous mowers were very easy, just pull the lever to the corresponding number. This machine you have to push in a button which when pushed will lower it immediately trying to raise the wheel height is incredibly difficult. To add insult to injury the little red clip that tells you what the height is is so poorly made that it fell off and can’t be reattached. Completely dissatisfied wish I hadn’t wasted my money on this piece of junk.
