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!

Thanks for making this work and providing great customer service! I had a full weekend with the install, but man was it worth it. The flywheel was such a good choice. I can't believe how much easier rev-matching down shifts are. The ACT is surprisingly easy to live with, even with the engagement point very low. I'll tackle that when it stops raining. Thanks again for making this happen this weekend.
