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:

  • 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.
