Former champion John Bowe says the decision to force mid-season aerodynamic changes on Ford's all-conquering Mustang makes a mockery of the Supercars championship.
Supercars announced on Tuesday testing had shown the Mustang - having won nine out of 10 races this season - held an unfair aerodynamic advantage over its Holden and Nissan rivals.
Bowe won the 1995 championship despite his Ford Falcon being forced to have its undertray trimmed before that season's endurance events and he took to social media to say "this sort of thing going on in the midst of the season makes a mockery of the series".
