THE setup day for the Ford teams ahead of the AirTouch 500 at The Bend has been a busy one, with outfits applying various parity adjustments that were announced ahead of the event.

Dick Johnson Racing, Tickford Racing and the Blanchard Racing Team arrived with tweaks pre-made, while Grove Racing and Walkinshaw Andretti United changed over parts today.

Changes to the Mustang’s Vehicle Specification Document revolve around the side skirt, the rear wing, the side door mirrors and a faster shift recovery setting.

With the S650 model Mustang GT that Will Davison started the 2025 season currently on display in the welcome centre at Shell V-Power Motorsport Park, a direct comparison between the old and new specifications can be made.
