"You can't change the past, you can only change the future. Internally you are frustrated and angry with yourself, but you have to focus and put it behind you.''
With 11 of the scheduled 29 races finished, the second part of the season is set up for a classic Holden (Whincup and Lowndes) versus Ford (Davison, Winterbottom) stoush to the end.
Whincup and Lowndes' Team Vodafone is under heavy challenge from the resurgent Ford Performance Racing, with Davison winning six of the 11 races and Winterbottom winning on Saturday at Phillip Island.
Lowndes acknowledges FPR has lifted markedly, but is confident his team won't let slip its dominance of recent years.
"The championship is so close, you can't afford to have 10 per cent go wrong for you,'' Lowndes said.
"We haven't slowed down, FPR have actually picked up their act.''
"It's great to have a championship where the competition's great between the two manufacturers.
"They were close last year, but didn't have the consistency they were looking for.''
The next races are in Darwin from June 15 to 17.
