Portefield R4-S Performance Street Pad F87 M2
For high performance and heavy duty street conditions the Porterfield R4-S compound re- mains a top performer in the realm of street/performance brake pads. With the R4-S compound giving a friction level up to .41. This is an amazingly fast stopping brake pad. Simply put, they will give you an impressive increase in stopping ability with very minimum amount of pedal effort. Perfect for prolonged everyday street driving while also being capable of enduring the most se- vere use without fade. It is also rotor friendly of course.
The team at Porterfield have gone to great measures to ensure that the R4-S compound has the absolute low- est noise and dust levels possible, far below O.E.M. equipment or any other high performance brake material. The R4-S compound which has an overall win in the Baja 1000 is available for most models of cars, trucks, and SUV’s. Superb stopping power under heavy use. Great for occasional autocrossing, solo events, off road events and rallies. Perhaps one of the overall best performing, clean and quiet everyday high performance driving brake pad ever made. The R4-S compound is available for virtually any vehicle sold in the U.S. Also for rare vintage cars and special applications for street touring.

I found the OEM pads to be pretty darn good on the street. What is the advantage of a street pad like this? Less brake dust? I would think if you are reaching the limits of the OEM pads on the street, you're probably due for a Darwin award (aka the Mustang at a Cars and Coffee)

Porterfield R4-S like most aftermarket performance pads tend to have slightly higher friction level, can handle a bit more heat and dust less. Some can find the higher operating temperature helpful during spirited driving in the backroads. |

Porterfield dust just a bit less than OE, but provides more linear brake torque. |

Potentially in the market for some OEM swap pads - my main bug is the OEM dust so anything that is the same or better (performance wise) but that dusts waaaaay less, and no squeak, would be good.
I noticed a comment above "these dust just a bit less than OE"....?? Anyone had any experience with these pad? in same vain as Endless, Pagid etc.. Last edited by BishUK; 02-09-2017 at 11:51 AM.. |

Thanks for the info, but having spent an hour or so Googling these pads over various car brand forums this afternoon it would appear these are not the pads for me - so my search continues.
