BMW E92 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 E92 3-Series and M3 delivers professional-level aerodynamic performance, blending precision engineering with lightweight strength. Developed using Computational Fluid Dynamics (CFD), the GTC-300 provides optimal aerodynamic balance, achieving an impressive 8.8:1 downforce-to-drag ratio for high-speed stability, cornering grip, and braking confidence.

The cambered airfoil design enhances rear-end traction by maintaining consistent airflow across the wing’s surface, while the adjustable angle of attack (0°–15°) allows drivers to fine-tune aerodynamic load for varying circuit or road conditions.

Constructed from pre-preg woven carbon fiber, each wing is autoclave-cured in billet aluminum molds for exceptional rigidity, durability, and a high-gloss finish. The 10 mm aircraft-grade 6061 billet aluminum pedestals offer adjustable mounting height and secure support, ensuring precision and stability under heavy aerodynamic forces.

The GTC-300’s mid-size configuration makes it an ideal aerodynamic upgrade for BMW E92 owners seeking the perfect combination of functional downforce, minimal drag, and refined motorsport-inspired aesthetics.
