Description
The Verus Engineering Carbon Rear Ducktail Spoiler for the 2015+ Subaru WRX VA combines a clean, aggressive appearance with functional aerodynamic performance. Developed from the ground up using advanced CAD design, vehicle scan data, and computational fluid dynamics (CFD), this carbon fiber spoiler is engineered to increase rear-end downforce without introducing a significant drag penalty.
Verus Engineering designed the spoiler with G3 continuity to create a smooth transition across the rear of the vehicle while maintaining an OEM-quality fit and finish. Development and aerodynamic testing were performed using OpenFOAM CFD to optimize the spoiler's shape and its interaction with airflow over the trunk.
The ducktail spoiler increases the high-pressure region over the trunk, generating additional rear downforce at speed. Compared with a larger rear wing, the spoiler provides an efficient way to improve high-speed rear-end stability while keeping additional aerodynamic drag to a minimum.
This makes the Verus Engineering Carbon Rear Ducktail Spoiler an excellent choice for vehicles that retain factory horsepower, where excessive drag from a large rear wing could negatively affect straight-line speed and potentially impact lap times.
The spoiler can also be paired with the Verus Engineering UCW Rear Wing for a significant increase in rear downforce. Its aerodynamic design works in conjunction with the high-efficiency rear wing without being detrimental to wing performance when both components are installed together.
Aerodynamic Performance
The rear of the vehicle naturally produces lift in the area where the ducktail spoiler is installed. By introducing the Verus Engineering spoiler, airflow over the trunk is controlled to create a higher-pressure region on the upper rear surface, producing additional rear downforce.
Verus Engineering specifically developed the trailing-edge geometry to maximize the primary downforce benefit while minimizing the associated increase in drag. The result is an efficient aerodynamic device that provides additional rear-end stability without the drag characteristics typically associated with a larger rear wing.
The spoiler is also designed to complement Verus Engineering's high-efficiency rear wing, allowing enthusiasts to combine both components when additional rear downforce is required.

Why Choose the Verus Engineering Carbon Ducktail Spoiler?
The Verus Engineering Carbon Rear Ducktail Spoiler is designed for drivers who want functional rear-end aerodynamic performance without the drag penalty of a large rear wing. Its CFD-optimized shape increases rear downforce while maintaining efficient airflow, making it particularly well suited to vehicles with factory-level power where minimizing drag remains important.
For drivers who require substantially more rear downforce, the ducktail can be combined with the Verus Engineering UCW Rear Wing to create a more aggressive rear aerodynamic package.
