Porterfield R4-s Rear Brake Pads for Porsche GT3, GT4, Turbo and More

Do you hate your squealing brakes on your Porsche 911 GT3, Turbo or Cayman GT4? Well so did we so we went on the hunt for a great street pad alternative. We have run these on our in house Cayman GT4 for the last year as street pads and they are everything we want out of a daily driven brake pad.

Still performance oriented but offer no squeal and minimal brake dust. So good in fact that we have also started using them on all applications we can. Porsche Cayenne, yup, on our daily driven one. Audi RS3 / TTRS, another great application as well as our colleagues Ford Mustang GT500. They are the real deal.

From the Manufacturer:

R4-S High Performance Street and Autocross – For high performance and heavy duty street conditions, the R4-S compound remains a top performer in the realm of street/performance brake pads. Perfect for everyday street driving while also being capable of enduring the most severe street use without fade. It is rotor friendly, low dust and squeal. We have gone to great lengths to ensure it is the absolute lowest noise and dust levels produced for a performance street compound. With this pad compound you will increase the friction level of your pads resulting in quicker stops. The pads will last longer and be more quiet and produce less dust than your current OEM pad.

Note: This pad is not recommended for track use.
