APR Performance Carbon Fibre GTC 300 Adjustable Wing Pin by Vasudev Behere on Beautiful in 2020 Curvy girl, Indian. This item is made to order, normal lead time is 2 3 weeks. Contact sales team at sales@aprperformance. com or 909 590 3796 for additional info. By purchasing, I agree to the terms outlined here All 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 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. **Mounting bases sit 47" apart (center to center)**.
