Description

These Wilwood GP320 brake calipers are compact, high-efficiency performers. Their 4-piston design weighs in at just 1.70 lbs. They were purpose-built as upgrades with increased pad size over 2-piston calipers on lightweight, open-wheeled race cars. Wilwood GP320 brake calipers are also well-suited to other performance and racing applications, including, but not limited to karts, motorcycles, mini-sprints, and formula sports racers. Their bridge configuration will accommodate rotors between 0.19 in. and 0.25 in. thick.
