How a 1mm error had Supercars champ driving a slower car all season

Red Bull Triple Eight Race Engineering driver Will Brown has been driving a car with an undersized airflow restrictor all season, which has resulted in him being 0.15 seconds per lap slower than other Mustangs. The issue, discovered by the team this week, affects the engine performance and lap times. Team principal Jamie Whincup apologized to fans and stakeholders for the oversight, stating that the undersized part was supplied by Supercars and expected to be the same for all 11 Ford Mustangs, distributed at the start of the season.

Supercars acknowledged the revelation, explaining that the undersized restrictor was only intended for demonstration purposes during a launch in February and was loaned to Triple Eight Race Engineering for that purpose.
