BMW E86 Z4 GT-250 Carbon Fiber Adjustable Wing

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

The APR Performance GT-250 Carbon Fiber Adjustable Wing for the BMW E86 Z4 is engineered to deliver motorsport-grade aerodynamic performance for time attack, autocross, and high-performance track applications. Designed using advanced Computational Fluid Dynamics (CFD), the GT-250 airfoil maximizes downforce while minimizing drag, resulting in dramatically improved high-speed stability, cornering grip, and braking confidence.

Constructed from autoclave-cured pre-impregnated carbon fiber, the GT-250 offers superior rigidity and strength-to-weight performance, maintaining consistent aerodynamic stability even under heavy load. The wing features an adjustable angle of attack ranging from 0° to 15°, giving drivers the ability to fine-tune aerodynamic balance for varying track layouts. High angles deliver increased rear traction and lateral grip, while low angles reduce drag for greater straight-line performance.

Aircraft-grade 6061 billet aluminum pedestals, available in multiple height options, ensure precise wing positioning for optimal airflow. With a highly efficient 7.6:1 downforce-to-drag ratio, the GT-250 enhances the Z4’s handling without compromising acceleration or top speed. A pre-installed 1/2" carbon fiber Gurney Flap further increases downforce and reduces flow separation for improved stability in high-speed cornering.

Designed for both vehicle-specific and universal installations, the GT-250 integrates cleanly onto the BMW E86 Z4 platform while delivering significant aerodynamic gains.
