The APR Performance GT-250 Adjustable Wing features a 2D airfoil shape that is designed to produce great downforce with minimal drag.
The GT Series airfoil is composed of lightweight and durable pre-preg carbon fiber composite materials for superior strength and low weight.
Side plate angles are easily adjusted using the included stainless-steel hardware.
Supporting the airfoils are 10mm "aircraft grade" 6061 billet aluminum pedestals that come in a flat black powder coat finish.
Computational Fluid Dynamics (CFD)
Modeled in 3D and validated using Computational Fluid Dynamics (CFD), the APR Performance GT-250 Adjustable Wing is designed to adapt to a variety of widebody sports and touring car applications.
CFD Data for the GT-250 Adjustable Wing (Click to View)
Contained herein are the data and results of the Computational Fluid Dynamics (CFD) analysis that was conducted on the GT-250 airfoil. This data illustrates how the airfoil performs in different conditions by comparing Downforce vs. Angle-of-Attack (AOA) vs. Speed, and Drag vs. AOA vs. Speed. This data will provide insight with regards to how and how much the airfoil performs with respect to these conditions.
To learn how to interpret and apply this type of CFD data, see sample analysis on the GTC-300 page.

Vehicle-specific and custom applications are listed below.
User assumes full responsibility for ensuring proper installation as intended. Professional installation by well-qualified personnel is highly recommended. The vehicle applications shown above are intended to work as a complete system when installed onto original vehicle body parts (i.e. trunk lids, hatches, etc.). To insure proper function and reliability, APR advises against modification or substitution of any component of the intended installation. Any modification or substitution of the airfoil, side plates, pedestals, mounting bases, mounting brackets, or hardware included with the wing kit may create unsafe operating conditions and ultimately cause this system to fail. Substitution of original vehicle manufacturer parts needed for the intended installation (i.e. rear trunk lid or rear hatch) with non-original parts may also create unsafe operating conditions and ultimately cause this system to fail.
