APR 2006-2008 BMW E85 Z4 GT-250 Adjustable Wing 61" bolt-on Note 1: A shorter superchargerAll GT Series wings feature an all new, low drag, aerodynamic 2D designed airfoil shape. The "2D" design allows the wing to maintain a consistent level of downforce across its entire span. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support validation of its aerodynamic design. Each GT Series airfoil is composed of lightweight and durable carbon fiber reinforced polymer (CFRP) composite materials. These airfoils contain
