Subaru WRX STI VA RB Duckbill Style Carbon Fiber Rear Trunk Spoiler 2015-2021

Enhance the rear styling and aerodynamic performance of your 2015-2021 Subaru WRX or STI with this RB duckbill style rear trunk spoiler. Designed for VA chassis models, this upgrade delivers a clean and aggressive OEM+ appearance while improving airflow over the rear of the vehicle.

The RB duckbill design features a subtle upward curve that extends from the trunk line, creating a sportier and more refined rear profile. Precision-engineered for proper fitment, it integrates seamlessly with the factory trunk for a smooth and cohesive finish.

Constructed from real carbon fiber or ABS plastic depending on configuration, this spoiler offers a balance of lightweight performance and durability. The carbon fiber option features a premium 3K twill weave finish, while the ABS version provides a cost-effective and resilient alternative for daily driving.
