GTC300 15 STI 67 Spec Win

The APR Performance GTC-300 Wing is a large carbon fiber wing, 67 inches wide and 13 inches tall, designed to provide optimal downforce for sports and touring car applications. It features a 3D airfoil shape, adjustable for balanced downforce, and is constructed from lightweight and durable pre-preg carbon fiber composite materials with a 2x2 twill weave pattern and UV-stable clear coat finish. The airfoil is supported by 10mm aircraft grade 6061 billet aluminum pedestals with a flat black powder-coat finish. Computational Fluid Dynamics (CFD) analysis was used to validate its aerodynamic design. It includes stainless steel machine screws, washers, and nuts. For installation on the 2015-2020 Subaru STI, it utilizes factory wing mounting holes. Installing on a WRX requires new holes to be drilled in the trunk lid.
