Description

These PolyMatrix A compound brake pads from Wilwood feature the ultimate friction material for severe-duty, extended high-temperature braking, and the highest friction torque for use with iron, steel, or titanium rotors. These pads provide immediate braking response at cold temperatures and throughout the temperature range. This makes them ideal for use on oval tracks, road courses, and other applications requiring high response at low temperatures.
