Features & Product Details

RallySport Direct carries a large catalog of quality carbon fiber exterior enhancements brought to you by APR. 

Here, you are looking at the APR GTC-300 Wing. This is a very large carbon fiber wing that is adjustable to provide your vehicle with optimal downforce under high-speed driving conditions. 



  • 67 inches wide
  • 13 inches tall
  • Adjustable
  • 3D airfoil shape that is designed to produce balanced downforce across its span on sports and touring car applications
  • Each GTC Series airfoil is composed of lightweight and durable pre-preg carbon fiber composite materials for superior strength and low weight
  • Aerodynamically-tuned side plates (end plates) included with every GTC Series Adjustable Wing which are critical components that help to ensure consistent airflow across the full span of the airfoil
  • Supporting the airfoils are 10mm aircraft grade 6061 billet aluminum pedestals that come in a flat black powder-coat finish
  • Modeled in 3D and validated using Computational Fluid Dynamics (CFD), the APR Performance GTC-500 Adjustable Wing is designed to adapt to a variety of widebody sports and touring car applications
  • Includes stainless steel machine screws, washers, and nuts


  • 2 x 2 twill weave pattern
  • Pre-preg carbon fiber 3K materials
  • UV-stable clear coat finish


  • This wing uses the factory wing mounting holes on the 2011-2012 STI Sedan for installation. Installing on a WRX would require new holes to be drilled in the trunk lid.

    5out of 5stars

    The APR GTC-300 wing its top quality! The install took about 30 mins to complete. The look is amazing. Set to 0 degrees on center deck makes 600+ NM of downforce at 80 mph and only 74 NM of drag!! A big improvement over oem in ride quality the vehicle is glued to the road on the lowest setting. Thank again for another great product RSD!

    DOWN FORCE? CHECK! 2 years ago
    5out of 5stars

    Quality product. If you are not comfortable drilling holes into your deck lid don't. Get a professional to install it. There are no installation manuals included. The 2017 STI required 2 holes drilled on each side. Once you are done it is quite sick. See you out there brethren.

    • Q: Would it fit a 2015+ WRX?  Sikkfreed1 year ago

      Would this wing fit the 2015+ WRX's? To my knowledge the trunks aren't any different and I like the position of the mounts on this one better than the other APR GTC wing.

        A:  This is only confirmed to fit on the STI because it will use some of the pre-drilled holes from the factory wing.
