The APR Performance GT-250 Carbon Fiber Adjustable Wing for the 2009-2012 Audi S4 is designed to provide high-performance aerodynamic balance, enhancing stability, cornering, and braking on the track or street. Engineered for efficient downforce generation with minimal drag, this wing is perfect for motorsports, autocross, and performance builds.
Its airfoil profile is precision-engineered and optimized using Computational Fluid Dynamics (CFD) to generate high downforce while minimizing drag. The cambered airfoil creates an effective pressure differential across upper and lower surfaces, ensuring maximum airflow attachment and reducing flow separation at high speeds.
The GT-250 features a fully adjustable angle of attack from 0° to 15°, allowing drivers to tune downforce and drag according to track conditions or driving preferences. Higher angles improve rear tire load and cornering traction, while lower angles reduce drag for maximum straight-line speed.
Constructed from pre-impregnated woven carbon fiber, the wing offers exceptional strength-to-weight ratio. Autoclave-cured in aluminum billet molds, it ensures durability, heat resistance, and consistent performance under aerodynamic loads. The wing mounts via aircraft-grade 6061 billet aluminum pedestals, with three heights available for precise airflow management.
A pre-installed Gurney Flap is included to further increase downforce and reduce flow separation, improving grip in high-speed cornering scenarios. The GT-250 combines race-inspired design with functional performance for drivers seeking enhanced aerodynamic control and high-speed stability.
