Championship leader Mark Winterbottom goes into the weekend looking to shore up his Championship hopes after a shaky weekend on the Gold Coast.
"You've just got to race," said McLaughlin. "You ... get in a position because of what has worked for the first 11 rounds, and you don't just change your position. Obviously, if you can beat him and he's [Lowndes] third, we're going pretty good."
Lowndes had a few wild off track excursions early in the day, before recovering to finish the day third. He's looking to continue momentum that has seen him close the gap to Winterbottom over the last two races.
"You've just got to focus on your own job," said Lowndes on chasing down Winterbottom. "If you win races it takes care of itself."
The Kiwis were all in the top half of the field in practice yesterday, with Shane van Gisbergen seventh fastest, Fabian Coulthard 10th quickest and Andre Heimgartner pushing the super Black Racing Ford to 12th fastest.
The ITM 500 continues today with final practice in the morning followed by two qualifying sessions and two races in the afternoon.
