Q: Why do carbon ceramic rotors resist fade better than iron on long sessions?

Carbon ceramic friction material has high thermal capacity and low thermal conductivity, so it absorbs enormous heat while keeping braking torque consistent and reducing pad wear at high temperatures. Iron rotors reach a point on extended runs where they heat-soak and the pedal goes long. With 15.5-inch front and 15-inch rear rotors, Stage 4 holds firm, precise pedal feel deep into sessions that would cook a smaller iron system.
