BMW E90 3-Series / M3 GTC-300 Carbon Fiber Adjustable Wing

This item is made to order, normal lead time is 2-3 weeks.

The APR Performance GTC-300 Carbon Fiber Adjustable Wing for the BMW E90 3-Series and M3 delivers proven aerodynamic performance for track and street applications. Engineered using Computational Fluid Dynamics (CFD), the GTC-300 is designed to generate efficient downforce while minimizing drag, offering a superior 8.8:1 downforce-to-drag ratio for balanced high-speed stability and cornering grip.

The cambered airfoil profile maximizes airflow attachment and reduces turbulence, improving traction and rear-end stability during aggressive driving. With an adjustable angle of attack (0°–15°), drivers can fine-tune downforce for technical corners or reduce drag for straight-line speed.

Constructed from pre-preg woven carbon fiber, each wing is autoclave-cured in aluminum billet molds, providing lightweight strength, rigidity, and exceptional durability under aerodynamic load. The 10 mm aircraft-grade 6061 billet aluminum pedestals feature adjustable risers for precision height and position control, ensuring an ideal aerodynamic setup for any track condition.

The GTC-300’s mid-sized design delivers a balance between performance and versatility—perfect for E90 M3 owners seeking genuine aerodynamic functionality, improved handling, and aggressive styling.
