BMW F82 M4 GTC-300 Carbon Fiber Adjustable Wing

This item is made to order normal lead time is 1–2 weeks.

The APR Performance GTC-300 Carbon Fiber Adjustable Wing for the BMW F82 M4 delivers professional-grade aerodynamic performance designed for motorsport precision and track-focused balance. Developed using Computational Fluid Dynamics (CFD), the GTC-300 optimizes downforce generation while minimizing drag, ensuring superior high-speed stability, braking control, and cornering grip.

With an adjustable angle of attack (0°–15°), the GTC-300 allows drivers to fine-tune aerodynamic response for any circuit or condition. Increase the angle for maximum rear traction on technical tracks, or reduce it to minimize drag for straight-line performance. The wing achieves an 8.8:1 downforce-to-drag ratio, delivering aerodynamic efficiency without sacrificing acceleration or balance.

Constructed from autoclave-cured pre-preg carbon fiber, the wing provides a superior strength-to-weight ratio and resists flex under extreme loads. Its 10 mm 6061 billet aluminum pedestals enable precise mounting, height, and angle adjustments, ensuring perfect aerodynamic integration with the M4’s aggressive body lines.

Designed for both form and function, the GTC-300 enhances the M4’s rear-end stability while providing a race-inspired aesthetic suited for high-performance street builds and full track applications alike.

Features:

• CFD-Optimized Airfoil Profile – Designed for high downforce and low drag performance.
• Adjustable Angle of Attack (0°–15°) – Fine-tune aerodynamic balance for street or track conditions.
• 8.8 : 1 Downforce-to-Drag Ratio – Delivers efficient aerodynamic grip and stability.
• Pre-Preg Carbon Fiber Construction – Autoclave-cured for high strength, lightweight rigidity, and durability.
• 6061 Billet Aluminum Pedestals – 10 mm aircraft-grade mounts for adjustable height and angle.
• Mid-to-Large Size Wing Design – Perfect balance between functional downforce and minimal drag.
• Vehicle-Specific Fitment for BMW F82 M4 – Engineered to align with M4 trunk contours and airflow path.
• Optional Carbon Fiber Gurney Flap – Adds additional rear downforce and airflow control (½″ height, 3M VHB tape).
• Mounting Options – Carbon or aluminum bottom plates for vehicle-specific or universal installation.
