Officials will further investigate Supercars driver Fabian Coulthard's "disgraceful" Bathurst 1000 safety car tactics after sensationally charging his Ford outfit with breaching team orders regulations.
Coulthard was initially slapped with a drive-through penalty after he dramatically slowed down and held up the field behind his Ford teammate Scott McLaughlin, who went on to claim his maiden Great Race on Sunday.
But Coulthard, who is third in the series standings, now faces a fine or loss of championship points after stewards ordered his DJR Team Penske team to face a hearing on the Gold Coast next week.
Officials will investigate whether Coulthard's actions influenced the outcome of the race after following team orders to slow down.
