BMW E92 3-Series / M3 GTC300 Carbon Fiber Adjustable Wing

Made to order with 1-2 week lead time. Contact sales@aprperformance.com or 909-590-3796 for details. The APR Performance GTC-300 Adjustable Wing delivers track-proven aerodynamic performance for BMW E92 3-Series and M3 models. This carbon fiber wing features a CFD-optimized airfoil design engineered for an 8.8:1 downforce-to-drag ratio, maximizing cornering grip while minimizing speed loss on straights. Fully adjustable angle of attack (0–15°) lets you dial in the perfect setup for any circuit condition. Higher angles boost downforce for enhanced traction and braking stability; lower angles reduce drag for improved top speed. Available in 61" or 67" spans with variable chord depth and height up to 13". Built from autoclave-cured pre-impregnated carbon fiber for lightweight strength and zero flex under load. Aircraft-grade 6061 aluminum risers enable precise height and position tuning. Choose vehicle-specific carbon fiber mounting plates or universal aluminum plates for your setup. Optional Gurney Flap adds additional downforce and reduces flow separation for maximum high-speed grip. Ideal for track cars, time attack builds, and performance street vehicles seeking serious aerodynamic advantage without compromise. Mounting bases position at trunk lid edges. CFD performance data available upon request.
