The game plan to win the 2018 Supercars championship is simple for Holden's Shane van Gisbergen - no more mistakes.
But that will be easier said than done at this weekend's crunch Pukekohe SuperSprint round after the Red Bull Racing star's error-riddled display that let his championship series lead slip.
Van Gisbergen heads into the season's second last round in his native New Zealand 14 points behind fellow Kiwi and Ford gun Scott McLaughlin, after a forgettable last round on the Gold Coast.
The 2016 Supercars champion was denied pole position for kerb-hopping in qualification for the Gold Coast 600's opening race before he and co-driver Earl Bamber limped home in 10th after receiving a drive-through penalty.
Van Gisbergen held a 19-point series lead before the Gold Coast debacle, but now finds himself again trailing season pace setter McLaughlin.
He was still kicking himself over the Gold Coast gaffes and admitted a repeat effort in the final two rounds would cost him the chance to win a second championship.
"It is going to be about no mistakes," van Gisbergen told the Supercars website.
"That is sort of what this year has been about. When we were clawing points back in the middle of the season, he (McLaughlin) wasn't making mistakes and he was always in the top five as well.
"That's what you need to do, be up there every week and minimise your bad days."
Van Gisbergen said he knew what needed to be done to win a cut-throat title battle with McLaughlin after holding out Red Bull Racing teammate Jamie Whincup to claim his maiden title two years ago.
"You don't have to do anything different to what you have been doing," the 29-year-old said.
"It comes down to these last two rounds but it has been the whole year. I am not treating it any different.
"Because it is so close I will still go out there and try and win them."
