PFC 11 Brake Pads – AP Racing 9660 Caliper

High-Performance Friction for AP Racing 9660 Caliper

The PFC 11 compound is a next-generation sprint and medium-distance friction material, developed for drivers who demand precise control, smooth modulation, and strong initial bite. Engineered as an evolution of the legendary PFC 01, the 11 compound offers enhanced pedal feel and more consistent performance over a wide temperature range — making it ideal for modern high-grip, high-brake-load applications.

These pads are a direct fit for the AP Racing CP9660 six-piston caliper, commonly found in professional-level motorsport and popular in upgraded braking packages on GT cars, time attack builds, and endurance race applications.

Why Choose PFC 11?

• Refined from the proven PFC 01 compound

• Strong initial bite with smoother torque application
