STI/WRX Brake Rotor Cool

APR Brake Cooling Ducts are engineered to deliver serious cooling performance where it matters most. Designed with an aerodynamically-optimized “funnel” profile, these ducts take advantage of the venturi effect—drawing in large volumes of air and accelerating it as it moves from the wide front opening into the narrower duct outlet. Paired with high-temperature ducting, they supply a continuous stream of fresh airflow to the brakes, helping reduce rotor temperatures and maintain consistent performance lap after lap. Excess heat is one of the most damaging forces in motorsports, affecting brakes, radiators, drivetrains, and more. APR Air Ducts bring targeted airflow to critical areas, improving cooling efficiency and protecting your investment. Constructed using pre-preg carbon fiber composites, they deliver exceptional strength, minimal weight, and a premium motorsport aesthetic. Features include Carbon Fiber Construction (autoclave-formed using pre-preg carbon fiber for an outstanding strength-to-weight ratio), Aerodynamic Venturi Design (funnels and accelerates airflow for maximum brake cooling efficiency at speed), and a UV-Resistant Clear Coat (finished with a durable UV-stable clear coat to protect against fading and environmental exposure).
