The APR Performance GTC-300 is a CFD-engineered adjustable wing delivering premium downforce with minimal drag for BMW M3/M4 track and performance applications. Fully adjustable angle of attack (0°–15°) lets you dial in the perfect balance for any circuit condition—maximize cornering grip or minimize drag for straight-line speed. Built from autoclave-cured carbon fiber with aircraft-grade aluminum risers, the GTC-300 achieves an 8.8:1 downforce-to-drag ratio while maintaining lightweight rigidity at high speeds. Available in 61" or 67" spans with variable chord depth and height options, it integrates seamlessly across both M3 and M4 platforms. Features include vehicle-specific carbon fiber or universal aluminum mounting plates, adjustable pedestals for fine-tuned airflow control, and an optional Gurney Flap for enhanced grip. Engineered for time attack, track days, and street-tuned builds demanding serious aerodynamic performance without compromise.
