The APR Performance GTC-300 Adjustable Wing delivers high-efficiency downforce with minimal drag for BMW E46 3-Series and M3 track applications. Fully adjustable angle of attack (0°–15°) lets you tune performance for any circuit condition—maximize downforce for cornering grip or reduce drag for straight-line speed. CFD-engineered airfoil achieves an 8.8:1 downforce-to-drag ratio, balancing rear-end stability without sacrificing acceleration. Pre-impregnated carbon fiber construction provides lightweight strength and rigidity at high speeds, while aircraft-grade 6061 aluminum risers enable precise height and angle adjustment. Available in 61" or 67" spans with variable chord depth (10"–12") and height (up to 13"). Fits vehicle-specific or universal applications with carbon fiber or aluminum mounting plates. Optional Gurney Flap adds additional downforce and reduces flow separation for enhanced cornering grip. Ideal for track cars, time attack builds, and high-performance street vehicles seeking improved stability and cornering performance.
