Carbon Fiber Subaru STI Brake Cooling Kit 2015-2017

STI Only.

The Carbon Fiber Subaru STI Brake Cooling Kit (2015–2017) from APR Performance is designed to deliver maximum brake cooling efficiency under high-performance driving conditions.

Utilizing aerodynamically-optimized carbon fiber ducts, this kit applies the venturi effect, channeling large volumes of air through the brake system to reduce rotor temperatures and maintain consistent braking performance. As vehicle speed increases, air pressure and velocity are accelerated through the duct’s narrow section, funneling cool air directly to the brakes.

Built using pre-preg carbon fiber reinforced polymer (CFRP), these ducts offer superior strength, durability, and lightweight performance. The UV-resistant clear coat finish provides protection against fading, heat, and environmental damage — ensuring both long-lasting functionality and an aggressive motorsport appearance.

When combined with high-temperature air duct hoses (sold separately), the system effectively minimizes brake fade, extends component life, and enhances braking consistency during both track and street applications.

Key Features

• Pre-Preg Carbon Fiber Construction – Lightweight and strong, formed in the autoclave under high heat and pressure.
• Venturi-Optimized Design – Funnels air efficiently for increased brake rotor cooling.
• Enhanced Brake Durability – Reduces thermal stress and prevents fade under repeated heavy braking.
• UV Resistant Coating – Clear-coated to withstand heat and environmental exposure.
• Performance-Driven Fitment – Designed specifically for Subaru STI (2015–2017).
• Functional Aerodynamics – Improves airflow management to critical brake components.
