Wilwood Caliper: GP 320

The GP 320 billet caliper has been FEA developed and fully CNC machined. This yields the highest possible clamping efficiency without deflection while providing balanced pad loading, all from a compact, lightweight four piston design. Corrosion free 1.25" diameter stainless pistons resist heat transfer from the pads to reduce thermal distortion in the piston bores, extend seal life, and reduce fluid temperatures to help prevent heat generated pedal fade. Quick-Clip pad retainers allow fast service of the top loaded pads 3.50" centered mount is easily adapted to common brackets provided by the spindle manufacturers. PolyMatrix “H” compound brake pads compliment this caliper and have a smooth, predictable engagement at all temperatures with continued positive response as pedal pressure is increased or brake temperatures rise. These pads yield a long wear rate and are fade resistance to over 1,300° F.
