APR Performance GTC 300 Carbon Fiber Wing for Infiniti G35 2003 2007 APR GTC 300 Adjustable Carbon Wing for 11 14 STi (AS 106763) APR Performance Carbon Fiber GTC 300 67" Adjustable Wing for 2015 2017 APR Performance Carbon Fiber GTC 300 67" Adjustable Wing for LX Dodge Universal Fitment GTC300 Carbon Fiber Adjustable Wing APR Performance. With a span of 67 or 61 inches and a height of 13 inches, the GTC 300 is an adjustable wing that means serious business. The GTC 300 3D airfoil shape allows for optimal airflow that reduces drag yet supplies an effective amount of downforce for your 2003 2007 Infiniti G35 Coupe. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support validation of its aerodynamic design. Each GTC Series airfoil is composed of lightweight and durable carbon fiber reinforced polymer (CFRP) composite materials. These airfoils contain pre pregnated woven carbon fiber sheets for superior strength and low weight. All CFRP airfoils are made using pre pregnated composite manufacturing processes (i. e. high temperature autoclave and vacuum bagging) in high quality aluminum billet molds. Supporting the airfoils are 10mm "aircraft grade" 6061 billet aluminum pedestals that come in a flat black powder coat finish. Special Note: Mounting bases sit at edges of trunk lid.
