The APR Performance GTC-300 Carbon Fiber Adjustable Wing for the 2009-2012 Audi S4 is engineered to maximize aerodynamic efficiency, downforce, and vehicle stability. Ideal for motorsports, track builds, and performance street applications, this wing improves cornering, braking stability, and high-speed balance.
The GTC-300 features a precision-engineered airfoil profile optimized through Computational Fluid Dynamics (CFD) to generate high downforce while minimizing drag. Its cambered design creates an effective pressure differential across the upper and lower surfaces, maximizing airflow attachment and reducing flow separation at high speeds.
With a fully adjustable angle of attack from 0° to 15°, the wing allows fine-tuning of downforce and drag to suit track conditions or driving preferences. Higher angles increase rear-end traction and cornering capability, while lower angles reduce drag for enhanced straight-line performance.
Constructed from pre-impregnated woven carbon fiber, the wing offers exceptional strength-to-weight ratio. Autoclave-cured in aluminum billet molds, it provides durability, heat resistance, and consistent aerodynamic performance under high loads. The wing mounts via aircraft-grade 6061 billet aluminum risers, allowing precise height and angle adjustment.
An optional Gurney Flap can be added to further increase downforce and reduce flow separation. This wing combines race-inspired design with functional performance for drivers seeking high-speed stability and superior aerodynamic control.
