2015–2023 Ford Mustang Track Pack Wicker Bill – Rear Wing Extension (Lexan)

Add aggressive motorsport styling to your 2015–2023 Ford Mustang GT Track Pack or Shelby GT350 with this Track Pack Wicker Bill rear wing extension. Designed to mount directly to the factory Track Pack spoiler, this upgrade enhances the aerodynamic appearance of the rear wing while giving your Mustang a race-inspired look.

Constructed from 3/16" Lexan, this wicker bill delivers excellent strength while remaining lightweight. The design features a black sub-wicker with a smoked center section, creating a layered performance aesthetic commonly seen on modern track-focused aero setups.

Each kit includes black stainless steel mounting hardware for a secure installation. Once installed correctly, the wicker bill sits slightly above the trunk deck to maintain proper clearance when opening and closing the trunk. Upgrade hardware are available HERE
