APR Performance Brake Rotor Backing Plate w/ Hose Kit 08-21 Subaru STI | Carbon Fiber Composite | Cooling Air Duct Kit
Overview
The APR Performance Brake Rotor Backing Plate with Hose Kit is engineered specifically for the 2008-2021 Subaru WRX STI models, designed to enhance brake cooling efficiency and protect critical components from excessive heat. This kit directs fresh airflow precisely to the brake rotors, helping to dissipate heat generated during aggressive driving or track use. It’s an essential upgrade for STI owners who demand reliable braking performance under high thermal loads.
Crafted from pre-preg carbon fiber reinforced polymer (CFRP), these backing plates combine lightweight construction with exceptional strength. The autoclave curing process ensures a high-quality finish and durability, while the UV-resistant clear coat protects against environmental damage. APR’s engineering approach focuses on functional improvements without compromising the OEM fitment and finish, delivering a product that integrates seamlessly into the STI’s engine bay.
By improving airflow to the brake rotors, this kit reduces the risk of heat soak and brake fade, which can lead to costly damage to brake components and surrounding systems such as the engine bay and transmission. For Subaru enthusiasts who push their STI hard on the street or track, this upgrade maintains consistent brake performance and extends the longevity of vital parts.
