Wilwood Race Brake Pads for GN4R/GN6R and AV6R, BP-45

Wilwood Engineering was founded by Bill Wood in 1977 in Camarillo, California. It designs and manufactures disc brake systems and components, including calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street and specialized applications. BP-45 brake pads in the .80-inch Grand National/AV6R configuration supply four replacement pads. Select individual components to meet the requirements of the complete brake system.

BP-45 combines high friction with useful cold response and a smooth increase in friction as rotor temperature rises. Wilwood lists it for racing applications with iron or steel rotors. Choose it around the car’s braking load and balance; a matching production-car pad shape does not make this a general street replacement.

Fitment & Compatibility

The Grand National GN4R/GN6R and AV6R radial-mount listings use this 0.80-inch configuration. Legacy GN III names can cover more than one pad thickness; compare the drawing and caliper cavity.
