■Street use only
It depends on combination of pads and conditions of road you drive on, it takes roughly 300km～1,000km of running-in on ordinary roads. During that period, please refrain from fast or abrupt driving or do not drive in a way as to force the temperature up. Running in of rotors will be completed simply via normal driving.
■Circuit use
istortion or cracks in rotors happen easier if optimum driving on a circuit is conducted straight from the beginning this in turn causes judders. When using a new rotor for the first time on a circuit, start with 50% braking for about 5 minutes and then go back to the pit once and take at least 5 minutes interval. After that, repeat 70～80% braking for about 10 minutes. Pit in again and take an interval of about 10 minutes. After that, gradually increase from 80% to 100% braking and the running in of rotors on circuit is completed.
