Thank you. You have rated this product.
For high performance and heavy duty street conditions the Porterfield 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 autocross or carving up your favorite canyon road.
Thanks to a carbon-kevlar compound, the R4-S provides improved performance over the OEM pad with a minimal increase in dust and noise. Additionally the R4-S is a rotor friendly compound that will extend the service life of your brake rotors.
For extended track use take a look at the Porterfield R4 or R4-1 brake compounds. Sean's Application Notes: This is a shop favorite for our light duty cars. If you are looking for a street performance pad that will not let you down, this is the one!
