A rare mistake from Shane van Gisbergen helped secure Supercars Race 4 honours for Chaz Mostert at Albert Park.
As was the case across for most of the weekend, van Gisbergen looked to have the pace on the field in the early stages of the Race 9, 20-lap finale.
He managed to past the likes of Waters, Percat and Mostert in the first five laps, before jumping the Dick Johnson Racing pair of Will Davison and Anton De Pasquale with his Lap 6 stop.
However Walkinshaw Andretti United’s pit work was slicker than Triple Eight’s, resulting in Mostert rejoining the race ahead of van Gisbergen.
Still, at that point it looked like van Gisbergen had Mostert’s measure – until Lap 9 when he locked his front-left into Turn 9.
The resulting flat spot taking the wind out of van Gisbergen’s sails, Mostert charging into the distance to grab a second win for the race weekend.
“We weren’t that competitive on the soft at the start, but the boys did a fantastic pitstop and we stuck to our strategy. That’s what you’ve got to do, put Shane under pressure. He obviously had a beast under him, but one little mistake. The team did such an awesome job. They gave us the win in the lane today.”
Van Gisbergen did his best to nurse his flat spotted tyre to the end and got within a lap of an unlikely second place until it finally let go.
Forcing him into another pitstop that left him 20th at the flag, Despite van Gisbergen’s mishap he was still able to secure the Larry Perkins Trophy for the most points across the weekend.
It also meant the rest of the podium was made up of the DJR cars, Davison finishing ahead of De Pasquale.
Cam Waters finished fourth on the road but was hit with a five second penalty for a pit infringement which dropped him to seventh.
That elevated Slade to fourth ahead of Brodie Kostecki and Percat.
Will Brown was next ahead of Broc Feeney on the road, however the Triple Eight rookie copped a five second penalty of his own for a pit infringement and was dumped down to 12th.
