Brake cooling is critical on race cars! The brakes reach temperatures well above 1,200 degrees and having efficient cooling is one of the most important elements to maximize braking capacity.
Kenny Brown Brake Cooling Ducts for 1996-2021 Mustangs are designed to provide the best cooling rates because they direct the air through the veins of the rotor, instead of directly on the rotor.
Directing the air through the veins allows the rotor to cool at the same rate on both sides. Directing the air on one side of the rotor will cause the temperature to be uneven and cause uneven pad wear along with compromised performance and efficiency.
