The APR Performance GTC-300 Adjustable Wing delivers track-proven aerodynamic performance for BMW E90 3-Series and M3 builds. This carbon fiber wing features a CFD-optimized airfoil engineered for an 8.8:1 downforce-to-drag ratio, maximizing cornering grip while preserving straight-line speed. Fully adjustable angle of attack (0–15°) lets you dial in downforce for tight corners or reduce drag on high-speed straights. Available in 61" or 67" spans with variable chord depth and height up to 13", the GTC-300 adapts to your specific track conditions and driving style. Built from autoclave-cured pre-impregnated carbon fiber for lightweight strength and rigidity at speed. Aircraft-grade 6061 aluminum risers enable precise height and position tuning for optimal airflow distribution. Choose carbon fiber or aluminum bottom plates for vehicle-specific or universal fitment. Optional Gurney Flap available for additional downforce and reduced flow separation. Mounting bases position at trunk lid edges for seamless integration. Ideal for track cars, time attack builds, and high-performance street vehicles seeking enhanced stability without excessive drag penalties.
