APR Performance GT-250 Adjustable Wing 61in for 2015-2018 BMW M4(AS-206182) 1553 Part # 827-556R) for 2015-2017All 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 pre
