Despite being on a super run of form, V8 Supercars champion Jamie Whincup is playing down his chances ahead of next month's Bathurst 1000.
The five-time V8s champion has overcome a mid-season slump to open up a 273-point series lead going into the 1000km endurance classic at Mount Panorama.
Victory in this month's Sandown 500 with co-driver Paul Dumbrell was Whincup's seventh win from his past 13 starts. A fifth Bathurst crown would put him on track to join Craig Lowndes (1996) and Peter Brock (1978, 1980) as the only men to win both endurance races and a championship in the same year.
But the Red Bull Racing driver says a $2 million resurfacing of the Mount Panorama circuit has him feeling unsure of his chances.
"With the resurfacing at Bathurst, to be honest, it's a little bit of a weakness for our cars on that really grippy surface," Whincup said.
