Chaz Mostert topped the second practice session at Phillip Island with a record-breaking lap.
The Prodrive Racing Australia driver made huge gains on his final run on the new-spec soft Dunlop control tyres, Mostert flying to the top of the times with a 1m29.574s – more than eight-tenths of a second clear of the practice lap record set by Scott McLaughlin last year.
Mostert wasn’t the only driver to go under the record, with the top nine cars all slipping under the benchmark.
The first was actually Fabian Coulthard, who went top with a 1m30.300s with seven minutes to go.
Shane van Gisbergen then dipped into the 1m29s with a 1m29.817s, with PRA pair Cam Waters and Mark Winterbottom slotting in behind with a 1m30.168s and a 1m30.171s respectively.
Mostert then beat them all with his storming run right at the flag.
Van Gisbergen ended up second with that time, having survived a moment at Turn 1 earlier in the session after suffering a right-front tyre failure.
Waters and Winterbottom were shuffled down to fifth and sixth by a pair of late times. McLaughlin was best of the late improvers, finishing third with a 1m29.916s, with Nissan’s Michael Caruso going fourth quickest with a 1m30.166s.
Coulthard’s time wound up only being good enough for seventh, ahead of Lee Holdsworth and Jamie Whincup. David Reynolds, who topped this morning’s first session, finished 10th.
Craig Lowndes didn’t take part in the session, the Triple Eight crew continuing to work on his damage Commodore following his heavy crash during the first session earlier today.
