Porterfield Brakes are race-bred friction designed and proven on the track. Each set is precision-cut from premium friction material and developed for high-temperature durability, fade resistance, and consistent pedal feel.

Available Compound Options for this Fitment:

  • R-4 — The original road racing compound that is very rotor friendly and easy to modulate. Medium friction with a 0–1200°F temperature range; optimum 350°F–900°F. Not for street use.
  • R4-E — The Endurance compound. Slightly lower friction than the R-4 but designed to wear longer for endurance races (4–6 hour). Characteristics are otherwise much the same as R-4. Not for street use.
  • R4-S — The performance street pad. Lowest dust and squeal of any street pad in the Porterfield line, very rotor friendly, and lasts as long as (or slightly longer than) stock pads. Not for track use. Not for use with CCM discs.
