The stage is set for a nail-biting Supercars series finish after Shane van Gisbergen looked like he'd snatched a last-gasp win over title rival Scott McLaughlin in the season finale's opening 250km race in Newcastle.
But the tables were turned when the winner received some bad news after an anxious wait on a stewards ruling before Sunday's battle with series leader McLaughlin that will decide the 2018 Supercars championship.
Officials convened on Sunday morning and handed van Gisbergen a 25-second penalty for a pit-stop breach during his dramatic win. The dramatic development stripped van Gisbergen of his win and saw him drop from first to fifth in the race result behind McLaughlin, David Reynolds, Jamie Whincup and Scott Pye.
The penalty also means McLaughlin extended his championship lead from two to 53 points ahead of van Gisbergen. Today's final race is worth 150 points.
Van Gisbergen remarkably reeled in McLaughlin on the 95th and final lap to clinch what looked liked a stunning victory.
