Steven Johnson blitzed the field in qualifying for Round 6 of Paynter Dixon Touring Car Masters at the Supercheap Auto Bathurst 1000.
There was a brief red flag interruption at the halfway point of the session with Allan Hughes (Holden Torana) and Tony Anderson (Chevrolet Monza) stranded out on track.
However, the session got back underway again with less than five minutes remaining, allowing for late improvements, with Johnson's best coming on his last flying lap.
John Bowe did likewise as he qualified his Holden Torana in 10th position.
The Touring Car Masters Trophy Race takes place on Friday at 0750 local time/AEDT followed by the first full points race of the weekend at 1525.
