The newest addition to the GTC Series is the GTC-500 Carbon Fiber Adjustable Wing. Spanning 70 inches, the GTC-500 is the largest aftermarket adjustable wing available. With its optimized 3D airfoil shape, the GTC-500 is perfect for high speed touring applications and supplies an ample amount of downforce without causing excess drag. All GTC Series wings feature an aerodynamic 3D designed airfoil shape to obtain the optimal balance of downforce. This design allows for a reduction in drag, yet maintains an ideal level of downforce. Computational Fluid Dynamics (CFD) Analyses were performed on these wings to support validation of their aerodynamic design. Each GTC Series airfoil is composed of lightweight and durable carbon fiber reinforced polymer (CFRP) or fiber reinforced polymer (FRP) composite materials. CFRP models contain pre-pregnated woven carbon fiber sheets for superior strength and low weight. FRP models contain woven pre-pregnated glass fiber sheets for high strength at reasonable weight. All CFRP and FRP airfoils are made using pre-pregnated composite manufacturing processes (i.e. high-temperature autoclave and vacuum bagging) in high-quality aluminum molds. Each GTC Series airfoil is composed of lightweight and durable carbon fiber composite. Supporting the carbon fiber airfoils are 10mm "aircraft grade" 6061 billet aluminum pedestals that come in a flat black powder coat finish.
