APR Carbon Brake Cooling Kit – Subaru STI 2018–2021

Specifically engineered for the Subaru STI (2018–2021), the APR Carbon Fibre Brake Cooling Kit delivers superior cooling performance to help manage intense track conditions. These aerodynamically optimised brake cooling ducts utilise the venturi effect to funnel large volumes of high-pressure, high-velocity air directly onto brake rotors, dramatically reducing heat build-up lap after lap.

Excessive brake heat can cause costly damage and reduce braking efficiency. APR’s lightweight, high-strength carbon fibre air ducts channel fresh airflow precisely where it’s needed most — protecting critical components such as brakes, transmissions, and differentials from overheating.

Manufactured using advanced pre-preg carbon fibre reinforced polymer (CFRP) composite materials, these ducts combine exceptional strength with a race-inspired lightweight design. Finished with a UV-resistant clear coat, they maintain their sharp appearance and durability even under harsh conditions.

Key Features:

• Designed exclusively for Subaru STI 2018–2021 models

• Aerodynamically optimised ducts using venturi effect for maximum airflow

• High-strength, lightweight pre-preg carbon fibre construction

• UV-resistant epoxy clear coat for lasting durability and finish

• Helps prevent costly brake overheating and improves track performance

Ideal for Subaru STI enthusiasts seeking premium brake cooling solutions and performance upgrades.
