Q: How much cooler do the ducts actually keep the brakes?

In testing, the carbon fiber brake cooling duct kit produced measured peak temperature drops of more than 200 degrees Fahrenheit at the rotor and caliper. Each side gets a carbon inlet, duct tube, high-temp flex hose, and a carbon air guide with heat-reflective shielding, routing air into the rotor’s internal cooling vanes for even inside-out cooling. Lower temps extend pad and rotor life while holding off fluid boil, and they keep pedal feel consistent deeper into a session.
