Upgrade the front braking system of your TCR or GT4‑spec race car with the PFC Brakes 331 Compound front pad set, part number 7790.331.25.44. Designed specifically for front‑axle applications using AP Racing 6‑piston calipers, this compound addresses the heavy braking loads, repeated stop dynamics and ABS control common in high‑level touring‑car or GT4 racing programs.
Unlike standard street or light track pads, this set features a full 25 mm pad thickness — giving you more friction material per stop, improved service life and better rotor conditioning under race‑duty loads. The 331 Compound is PFC’s next‑generation endurance‑race material, developed to deliver higher initial torque than their 08 compound, smoother release and a stable friction curve throughout long sessions.
Installation should be done with precision, and proper pad bedding (per PFC’s guidelines) is required to unlock full potential. Whether you’re prepping for a touring car sprint, long stint race or club GT4 event, these front pads deliver the robustness, pedal feel and repeatability that serious teams demand.
