APR Carbon Rear Diffuser – Subaru WRX/STI 2002–2007

Upgrade your Subaru Impreza WRX/STI (2002-2007) with the APR Performance Carbon Fiber Rear Diffuser, engineered to enhance aerodynamic efficiency and downforce. This precision-crafted rear diffuser works in harmony with other aerodynamic components to optimise airflow beneath the vehicle, reducing drag and improving high-speed stability.

As your car moves forward, turbulent low-pressure air forms at the rear, creating lift and reducing grip. The APR rear diffuser channels high-speed airflow smoothly into this low-pressure zone, effectively managing air turbulence and encouraging a more stable, controlled driving experience. This results in improved downforce, better traction, and enhanced performance during aggressive driving or track use.

Manufactured using aerospace-grade pre-preg carbon fiber and cured under high temperatures in an autoclave, this diffuser offers exceptional strength-to-weight ratio. The UV-resistant clear coat finish protects the diffuser from environmental damage, ensuring lasting durability and a premium, race-inspired look.
