GT250 Audi S4 67 Spec Win

The APR Performance GT-250 Adjustable Wing is a high-performance aerodynamic component designed for motorsport, autocross, and track applications. It features a low-drag, aerodynamic 2D airfoil shape with consistent downforce across its span, validated by Computational Fluid Dynamics (CFD) analysis. Constructed from lightweight, durable pre-impregnated woven carbon fiber composite materials using high-temperature autoclave and vacuum bagging processes in aluminum billet molds. It offers a fully adjustable angle of attack (0° to 15°) for precise tuning of downforce and drag, achieving a 7.6 to 1 downforce-to-drag ratio. Mounting is via aircraft-grade 6061 billet aluminum pedestals (10 mm thick) available in three heights. Designed for both vehicle-specific and universal fitment. Includes a pre-installed ½ inch (12.7 mm) pre-preg woven carbon fiber gurney flap attached with 3M VHB double-sided tape to further increase downforce and reduce flow separation.
