Aerodynamic changes to Mustang after parity review

Changes to the Gen3 Ford Mustang ahead of Townsville.

04 July 2023

Supercars has announced that changes will be made to the specifications of the Ford Mustang ahead of this weekend’s NTI Townsville 500.

The decision comes after a parity review conducted in accordance with the Supercars championship regulations, after the parity review was triggered following the Chevrolet Camaro’s domination in 2023.

After a review conducted by the Supercars head of motorsport, data from the Chevrolet Camaro and Ford Mustang was compared using a multi-lap overlay.

According to Supercars, the overlay reflected a minor difference in rear downforce of the Mustang and its performance in the braking zone.

Supercars partnered with D2H for computational fluid dynamics (CFD) analysis, which revealed that adjustments needed to be made to increase the rear downforce of the Mustang.

The recommended changes involve modifying the position, span, and angle of the rear wing, and increase the size of the boot spoiler on the Ford Mustang.

Supercars CEO Shane Howard said: “Firstly, we would like to thank the Homologation Teams and D2H for their extensive work on this review.

“It required a considerable amount of man hours, expert analysis, and communication to work together to present these adjustments for approval.

“With these changes in place, Supercars is looking forward to racing at this weekend’s NTI Townsville 500.”
