Product Description

Spanning up to 71 inches over its optimized 2D airfoil shape, the APR Performance GTC-250 Adjustable Wing Swan Neck supplies maximum downforce in widebody sports and touring car applications. Swan Neck mounting maximizes effective airfoil surface area and minimizes flow separation.


  • More downforce than the GT-250 standard pedestal version
  • Angle adjustment holes allow for easy tuning of downforce
  • Reinforced pre-preg carbon fiber withstands extreme loads


  • Pattern – 2×2 twill weave
  • Material – Pre-preg carbon fiber, 3K
  • Coating – UV-stable clear coat
  • Wing Measurement – Custom span Up to 71”, 10” chord
  • Hardware – Stainless-steel machine screws, washers, and nuts
  • Mounting
    • 6061 billet aluminum brackets/pedestals (no mounting bases included), custom fabrication of chassis-mounts required (double-shear recommended)
    • Swan neck pedestal dimensions: 32” overall height x 13.5” overall width x 3/8” thickness
    • Standard swan neck pedestal-to-pedestal length: 23” (custom lengths can be accommodated up to 50”)


  • The APR Performance GT-250 Adjustable Wing Swan Neck features a 2D airfoil shape that is designed to produce great downforce with minimal drag. Swan neck pedestals prevent downforce-robbing flow separation commonly found in standard bottom-mount pedestals. The swan neck design allows greater Angle-of-Attack (AOA) before stalling occurs, when compared to standard bottom-mount pedestal configurations.
  • The GT Series airfoil is composed of lightweight and durable pre-preg carbon fiber composite materials for superior strength and low weight. For the swan neck application, the airfoils are internally reinforced differently from the non-swan neck airfoils.
  • Supporting the airfoils are 10mm “aircraft grade” 6061 billet aluminum swan neck pedestals that come in a flat black powder coat finish. Each swan neck pedestal is also “knife-edged” at the trailing edge, to minimize the amount of “dirty” air that reaches the airfoil.

  • Note:* Upper brackets shown in photos are raw aluminum (for illustration purposes only). All production units come powder-coated in black color (same as the pedestals).

Gurney flaps are included with every APR Performance GT-250 Adjustable Wing. These are super lightweight, made using pre-preg carbon fiber processes, and pre-attached using double-sided tape.
