Features & Product Details

With a 67” wing span, the APR GTC300 Carbon Fiber Wing is the perfect aerodynamic addition that will provide sufficient amounts of downforces where you need it the most. 

The APR GTC300 features Computational Fluid Dynamics (CFD) analysis, which was performed on this wing to support the validation of its aerodynamic design. Each GTC Series wing is crafted from lightweight, and durable carbon fiber composite.

Also included in the kit to support the wing span are 10mm aircraft grade 6061 billet aluminum pedestals that come in a flat black powder-coated finish that will outlast the elements. 

Best of all, the wing covers the factory mounting provisions in the trunk lid, however additional holes must be drilled to complete the installation.

Awesome look! 1 year ago
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

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.
