Audi S4 GTC-300 67" Carbon Fiber Adjustable Wing 2009-2012

This item is made to order, normal lead time is 2-3 weeks.

The APR Performance GTC-300 67" Carbon Fiber Adjustable Wing for the 2009–2012 Audi S4 is a track-proven aerodynamic upgrade engineered for superior stability, traction, and cornering performance. Designed through Computational Fluid Dynamics (CFD), this wing generates an outstanding 8.8:1 downforce-to-drag ratio, allowing the vehicle to maintain excellent cornering balance without compromising top-end speed.

The cambered 3D airfoil profile produces efficient downforce while minimizing drag. Its adjustable angle of attack (0°–15°) lets you tailor aerodynamic balance for different track layouts—higher settings provide increased traction for technical corners, while lower settings reduce resistance on long straights.

Built from autoclave-cured, pre-preg woven carbon fiber, the GTC-300 offers exceptional rigidity, durability, and a lightweight structure that resists flex at high speeds. Supporting the wing are 10 mm aircraft-grade 6061 billet aluminum pedestals, which allow precise height and angle adjustments for optimal airflow management.

Ideal for performance-oriented Audi S4 owners, this wing delivers a blend of functional downforce, refined design, and professional-grade construction suitable for both street and track applications.

Features:

• CFD-Engineered Airfoil Design – Provides high-efficiency downforce with minimal drag for aerodynamic balance.
• Adjustable Angle of Attack (0°–15°) – Fine-tune downforce and drag to match circuit conditions or driving style.
• 8.8:1 Downforce-to-Drag Ratio – Optimized for high-speed stability, cornering grip, and braking confidence.
• Carbon Fiber Construction – Made from autoclave-cured pre-preg carbon fiber for lightweight strength.
• Aircraft-Grade Billet Pedestals – 10 mm 6061 aluminum risers with angle-adjustable mounting for precise control.
• Compact Mid-Size Design – Offers an ideal balance between performance downforce and everyday drivability.
