Description
The Verus Engineering UCW Rear Wing Kit is designed specifically for the VA Subaru STI enthusiast looking for a significant increase in rear downforce. Developed for track-focused driving, the UCW rear wing increases rear-end aerodynamic grip, improves high-speed confidence, and can help reduce lap times by allowing higher cornering speeds.
The UCW bridges the performance gap between Verus Engineering's Swan Neck High-Efficiency Rear Wing and the larger 300mm V1X airfoil. Featuring a 250mm curved chord, the UCW generates more downforce than Verus Engineering's high-efficiency rear wing while producing significantly more downforce than similarly sized competitor wings.
The airfoil was optimized using advanced aerodynamic analysis software and further refined through CFD testing to ensure effective airflow over the wing when installed on the vehicle. Verus Engineering also utilized in-house vehicle scan data during development, resulting in a rear wing system with a near-OEM fit and finish.
The UCW is an ideal solution for track enthusiasts who need a substantial increase in rear downforce to balance a significant front aerodynamic package.

Aerodynamic Science
The Verus Engineering UCW Rear Wing was specifically developed for the VA WRX/STI platform to provide substantially more rear downforce than Verus Engineering's high-efficiency rear wing.
The UCW airfoil is capable of generating aerodynamic downforce across an angle of attack range from 0 to 15 degrees, allowing the wing to be adjusted according to the vehicle's aerodynamic requirements and overall setup.
As part of the Verus Engineering Ventus 3 aerodynamic package, the UCW rear wing works alongside the rest of the aerodynamic system to provide a significant increase in total vehicle downforce. This additional rear grip can help balance a substantial front aero package while increasing cornering confidence and reducing lap times.
During development, Verus Engineering used advanced CFD analysis to optimize the airfoil and verify that the wing would receive adequate airflow in its installed position. The company then validated the aerodynamic design through real-world testing.
The CFD results and experimental testing demonstrated a strong correlation, with real-world performance closely matching the aerodynamic predictions. This validation supported both the CFD methodology and the UCW's overall aerodynamic performance.
Installation
The UCW Rear Wing Kit is designed to mount directly to the OEM trunk using machined aluminum trunk mounts and a load-transferring mounting system.
The kit includes a dedicated drill template, trunk load-transfer hardware, double-sided trunk tape, and the necessary stainless hardware for installation.
Professional installation is recommended to ensure accurate drilling, proper load distribution, and correct wing alignment.
