The GP 320 uses Wilwood type 6211 brake pads. The pads measure .44" (11,2mm) thick with an overall length of 2.74" ( 69,6mm). This represents nearly a 50% increase in pad area over some of the popular two piston calipers used on similar applications. The 6211 pad is available in PolyMatrix "H" compound which provides predictable engagement, high friction, long wear, and extreme high temperature fade resistance in the harshest conditions.
Other Wilwood performance enhancements include high temperature square faced bore seals that provide a wide sealing area with positive piston retraction on release. Quick-Clip retention pins provide easy access for pad service without caliper removal. The calipers are finished in signature Wilwood high luster black anodizing for protection against corrosion and the elements.
