The Wilwood GP 3230A billet four piston caliper is a compact, high efficiency performer. Weighing just 1.70 pounds, it was purpose built as an upgrade with increased pad size over two piston calipers on lightweight open wheeled racecars. Newly updated to a dual bleeder design, the caliper can now be installed both left hand and right hand inclinations. The GP 320A is also well suited for racing applications including karts, motorcycles, mini-sprints, and formula sports racers. The GP 3230A bridge configuration will accommodate rotors between .75" and .81" thick, with overall diameters between 9.00" and 11.50".
