03 Compound has shown to have higher bite and higher average torque than 01 Compound. 03 have very good initial bite, and there is a slight rise of torque with temperature to handle severe conditions. 03 has excellent modulation and release characteristics, less torque scatter than competing pads, and very good disc conditioning properties. Requires finesse so as not to over slow or overwhelm the car’s set-up in some venues. 03 can be replaced with 05, 07 or 13 compounds. 03 Recommended Applications: High grip and high downforce applications, NASCAR Short Track and Road Course, Champcar, Professional GT and Daytona Prototype.
