The Porterfield R4-S compound is a top performer in the street/performance market with the R4-S compound giving more friction level (up to .41) than OEM pads.

Offering fast stopping power with minimum amount of pedal effort making them ideal for prolonged everyday street driving and capable of enduring severe use without fade. The R4-S compound provides low noise and dust levels whilst also being rotor friendly. Perhaps one of the best overall performing, clean, and quiet everyday high performance driving brake pads ever made and still able to take the abuse from occasional track and road events.
