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.
  • R4-1 — The Vintage compound. Designed for vehicles that struggle to keep heat in the pads. Best when temps are under 600°F and peak temps stay below 1000°F. Also popular as an autocross pad. Not for street use.
