APR Brake Rotor Cooling Kit | 2013-2020 Scion FR-S (CF-505658)

The APR Brake Cooling Ducts are aerodynamically-optimized to “funnel in”
massive amounts of air. Also known as the venturi effect, when the vehicle speed
increases, this funneled-in air increases in both pressure and velocity as it passes
from the larger frontal area into the smaller pipe section of the brake duct. When
matched with appropriate High-temperature air duct hoses that connect to the rotor
backing plates the cooling cycle is completed and large volumes of fresh air help
cool down red-hot brake rotors lap after lap on the track. The APR Brake Cooling
Kit is a three piece kit that includes Carbon Fiber Brake Ducts, High-temperature
Silicone hoses, and Carbon Fiber Rotor Backing Plates.
