A number of changes have been allowed to the Gen3 Mustang, including alterations to the rear wing, side skirt and front fascia elements.
The changes should reduce drag and redistribute downforce to the rear of the car, according to a statement by Supercars.
The overhaul had been considered imminent after the championship announced a parity review - its second of the season - in the wake of the Bathurst 1000.
It is believed that the parity threshold had been triggered at the Great Race due to the disparity in speed between the Ford Mustang and the Chevrolet Camaro, prompting Supercars to consider adjustments to their relative performances.
These adjustments were officially confirmed on Tuesday, with all Ford teams now allowed to bring updated aero to Surfers Paradise for the penultimate round of the season.
“After a comprehensive evaluation conducted by Supercars, and in consultation with the Homologation Teams, it has been determined that adjustments will be implemented to the Ford Mustang Vehicle Specification Document in preparation for the Boost Mobile Gold Coast 500 event,” read a statement.
“These modifications include alterations to the rear wing, side skirt, and front fascia elements, with the primary aim of reducing drag, and redistributing downforce to the rear of the Mustang.”
