The GP 320 billet four piston caliper is a compact, high efficiency performer. Weighing just 770gram, it was purpose built as an upgrade with increased pad size over two piston calipers on lightweight open wheeled racecars. The GP 320 is also well suited to other performance and racing applications including, but not limited to karts, motorcycles, mini-sprints, and formula sports racers. The GP 320 bridge configuration will accommodate rotors between 19.05mm and 20.5mm thick, with overall diameters between 228.6mm and 292.1mm.
