GP200 Caliper
The GP 200 billet caliper represents the newest lightweight (only .90 pounds) caliper specifically designed for
tight fit applications while utilizing a standard 2.38" lug mount. Combines superior strength with a black anodized
finish along with several new performance features. The strength of the GP 200 is a combination of process and
design. GP 200 calipers are fully CNC machined from premium grade alloy billet. Use 4908 type pads.

GP 320 Calipers
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 race
cars. 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" and .25" thick, with overall diameters between 9.00" and 11.50". Use 6211 type pads.
