The APR Performance GTC-300 Adjustable Wing is a high-performance aerodynamic component engineered for the BMW G80 M3 and G82 M4. Designed for track, time-attack, and high-speed driving, this wing optimizes downforce while minimizing drag, improving cornering stability, braking, and overall vehicle balance.
Constructed from autoclave-cured pre-impregnated carbon fiber, the GTC-300 delivers exceptional strength-to-weight performance. Its cambered airfoil profile has been optimized using Computational Fluid Dynamics (CFD) to maximize airflow attachment, minimize separation, and achieve an 8.8:1 downforce-to-drag ratio. The fully adjustable angle of attack (0°–15°) allows fine-tuning for specific track conditions, balancing downforce for tight corners or low drag for high-speed straights.
Mounted on 10mm billet aluminum risers, the wing height and position can be precisely adjusted to control airflow and downforce distribution. Optional carbon fiber Gurney flaps further increase downforce and enhance high-speed cornering grip.
The GTC-300 combines lightweight carbon fiber construction, adjustable aerodynamic tuning, and precision mounting, providing BMW enthusiasts with a versatile solution that enhances performance, handling, and visual appeal on the track and street.
