Audi S4 GT-250 Carbon Fiber Adjustable Wing 67" 2009-2012

This item is made to order, normal lead time is 1-2 weeks.

The APR Performance GT-250 67" Carbon Fiber Adjustable Wing for the Audi S4 (2009–2012) is engineered to deliver advanced aerodynamic performance for competitive track use, autocross, time attack, and high-performance street driving. Using Computational Fluid Dynamics (CFD), the GT-250 airfoil is designed to maximize downforce while minimizing drag, increasing rear-end stability, cornering grip, and high-speed control.

Crafted from autoclave-cured pre-impregnated carbon fiber, the wing offers exceptional rigidity and a superior strength-to-weight ratio, ensuring consistent aerodynamic behavior at high speeds. The airfoil maintains stable airflow attachment and reduces flow separation, providing predictable handling and improved vehicle balance.

The GT-250 features a fully adjustable angle of attack ranging from 0° to 15°, allowing drivers to fine-tune downforce for specific tracks or driving conditions. Higher angles deliver stronger cornering grip and braking stability, while lower angles reduce drag for increased straight-line speed. With its optimized 7.6:1 downforce-to-drag ratio, the GT-250 delivers substantial performance gains without excessive aerodynamic resistance.

Mounted using 10 mm thick aircraft-grade 6061 billet aluminum pedestals, the wing offers precise height options and robust structural support. Designed for both vehicle-specific and universal fitment, the GT-250 integrates cleanly on the Audi S4 platform. A pre-installed 1/2" carbon fiber Gurney Flap provides additional downforce and enhanced high-speed grip.
