BMW F82 M4 GTC300 Carbon Fiber Adjustable Wing

BMW F82 M4 GTC300 Carbon Fiber Adjustable Wing — High-Performance Track Aerodynamics Made to order with 1–2 week lead time. Contact sales@aprperformance.com or 909-590-3796 for details. The APR Performance GTC-300 is a precision-engineered adjustable wing built for track cars and high-performance vehicles demanding superior cornering stability and aerodynamic balance. CFD-optimized airfoil design delivers an 8.8:1 downforce-to-drag ratio, maximizing grip without sacrificing straight-line speed. Fully adjustable angle of attack (0°–15°) lets you tune downforce and drag for any circuit condition—increase angles for tight corners, reduce them for high-speed straights. Autoclave-cured carbon fiber construction provides lightweight strength and rigidity under extreme loads, while aircraft-grade 6061 aluminum risers enable precise height and position adjustment. Available in 61" or 67" spans with variable chord depth and height. Includes vehicle-specific or universal fitment options. Optional Gurney Flap available for enhanced downforce and reduced flow separation. Ideal for time attack builds, dedicated track cars, and street-tuned performance vehicles seeking measurable aerodynamic gains.
