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.

Simply put, it’s a miracle product
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
There’s a reason this product won the best consumer product of the year, 40,000 customers voted on this product as the most innovative product of the year for car care. Personally it has stopped my 185,000 mile, 16 year old Subaru EJ253 engine from consuming/burning oil in just 2 3,000 mile interval oil changes. I was previously burning about a quart of oil every 1,000 miles before using the Valvoline restore and protect and it has already done its job and then some. Not only have I stopped consuming oil, I’ve seen roughly a +3mpg increase compared to the times I’ve used and tracked MPG while using Shell Rotella T6 and Pennzoil Ultra Platinum; it doesn’t end there either as I regularly check my engine oil dipstick out of habit because the car used to burn oil and I had to stay on top of the oil level. Upon checking my oil level at 1,000 miles into the second oil change I was shocked to see how clean the Valvoline oil was on the sides of the dipstick, using other oils and checking them at that interval has always had my oil looking quite black and dirty just 1000 miles after a change, this was not the case with the restore and protect; it came out at 1000 miles looking very clean, translucent and not discolored. I can’t recommend this product enough, especially at the price point compared to competitors; I will always have a jug of this stuff in the garage.

Incredible motor oil !
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
I've used this in my 2014 Buick Encore with 91k miles on it for 2 oil changes and the results are extremely impressive. The engine in the 'ole gal is noticably quieter and my gas milage is definately improving. I switched from Mobil 1 to this oil based primarily on reviews and I'm glad I made the switch. This vehicle is not only my commuter car (80 miles per day), but it's my "winter" vehicle so it sees some temperature extremes. This oil is remarkable ! Time will tell, but I definately recommend it.

Good! I would buy this again if needed.
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
Good! I would buy this again if needed. The best oil to use in a KIA, IMO. Keeps it clean and might help prevent oil burning. Your KIA needs the best oil you can feed it. They are known for failing engines so why not give it the best, especially if its out of warranty like mine!

USE THIS 3 yr old-10yr old cars But it is not for use for classic muscle car-flat tappet cams
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
Valvoline has come up with a tested, amazinng engine oil for not the newest cars..but for cars say 3-10 years old that may have some varnish-sludge build up..works slowly enough over time so it doesnt suddently clog the filter, but DO change oil and filter at 3500, not more. In fact 3500 to 4K max for ANY car, any time. DO NOT go longer as some mfg or oil say you can. Tests show that sludge builds up. This oil is NOT for classic muscle cars with flat tappet cams.

Amazing Oil!
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
So far after first oil change it made my Toyota Tundra 5.7L with 255k miles run smoother and quieted the timing chain tensioner knock that I was quoted $5k and up to repair! Will be using from now on to 500k miles plus!
