GP320 Caliper
The GP 320 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. 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 .75" and .81" thick, with overall diameters between 9.00" and 11.50".  

Caliper is full CNC detail machined from premium alloy billet. FEA structural analysis technology was employed to develop a design that minimizes weight and maximizes rigidity against deflection. Full width bridges are reinforced with four, high strength steel cross bridge bolts. The cross bridge bolts are coated for corrosion resistance and provide added resistance to deflection and body separation under high loads. Internal fluid ports with a single outboard bleeder provide quick and effective evacuation of gasses and spent fluid.   Continue >>
