ADRO A18A30-1301 Carbon Fiber Rear Diffuser for TOYOTA GR Yaris (GEN 1) 2020+ The ADRO A18A30-1301 carbon fiber rear diffuser is engineered for the Toyota GR Yaris (Gen 1) to enhance rear-end aerodynamic performance and vehicle stability. Developed using CFD testing, this component integrates with the factory aerodynamic platform, contributing to increased overall downforce while maintaining minimal drag. Constructed from wet carbon fiber, the diffuser is precisely shaped to follow the OEM rear bumper contours. By accelerating airflow exiting from underneath the vehicle, it creates a low-pressure zone that increases rear downforce, improving high-speed stability and cornering control. - CFD-developed design for optimized aerodynamic efficiency - Supports total downforce increase of approximately 165 lbs (734 N) - Accelerates underbody airflow to generate rear-end downforce - Enhances high-speed stability and cornering performance - Manufactured from wet carbon fiber for strength and reduced weight Specifications: - Material: Wet Carbon Fiber What’s in the box: - 1 Rear Diffuser - 3M Tape - Screws
