The Supercars championships has been turned on its head with Red Bull Holden star Jamie Whincup penalised and dropping to fourth in the standings.
The seven-time champion received a 38 second post-race time penalty late on Saturday night for turning off his pitlane speed limiter in the first race of the Phillip Island 500 earlier in the day.
Whincup finished second behind championship leader Scott McLaughlin in the 250km race, but the penalty dropped him to 14th, meaning David Reynolds and Shane van Gisbergen overtake him in the overall standings.
He was just one point behind McLaughlin (797) following the race, but his costly mistake means he is now 76 in arrears going into Sunday's second leg.
