Description

If you're running a Grand National III caliper setup and need predictable braking performance across varying track temperatures, the Wilwood PolyMatrix B pads deliver medium-high friction with exceptional cold bite—meaning you get consistent stopping power from the opening lap through extended high-temperature sessions. These pads are engineered to resist fade in racing environments up to 1300°F while maintaining a low wear rate at moderate temps, reducing unscheduled pad changes during competition. With a straightforward bedding process and full compatibility across iron and steel rotors, they're a bolt-in solution that requires zero fabrication.
