BMW G80 M3/ G82 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 G80 M3 and G82 M4 delivers track-proven aerodynamic performance designed for precision and stability at high speeds. Engineered through Computational Fluid Dynamics (CFD) analysis, this wing enhances rear downforce with minimal drag, providing improved grip, cornering stability, and braking balance for both street and track applications.

The 0°–15° adjustable angle of attack allows drivers to fine-tune aerodynamic load according to driving conditions. Increase the angle for maximum rear-end traction during tight, technical corners, or decrease it for reduced drag on long straights. The GTC-300’s 8.8:1 downforce-to-drag ratio ensures optimal aerodynamic efficiency, maintaining balance and speed even at extreme conditions.

Built from autoclave-cured pre-preg carbon fiber, the GTC-300 provides exceptional strength, light weight, and resistance to flexing under aerodynamic loads. The 10 mm 6061 billet aluminum pedestals allow precise height and angle adjustments, integrating seamlessly with the G80/G82 chassis for an aggressive, race-ready look.

Perfectly blending form and function, the APR GTC-300 is the ultimate aerodynamic upgrade for BMW enthusiasts seeking high-performance handling, improved rear stability, and a commanding motorsport aesthetic.
