The Bend track serves as the last sprint round before the championship moves to endurance mode and the two Kiwis – McLaughlin and Van Gisbergen – hold a significant but not unassailable lead at the top the standings.
Red Bull Holden racer Van Gisbergen has won three of the last four races in the championship and has closed the margin to McLaughlin to just 89 points.
"It has been going well," Van Gisbergen said of his team's improvement in recent rounds. "The championship battle is close but pretty awesome every week.
"I think we are just slowly starting to understand out new ZB Commodore a bit. We had a really good start to the season and they struggled on the open and flowing tracks and that is what we have got this weekend.
"Hopefully we see the improvement we have done and we can keep that momentum going."
Predictions
Man to beat: It is impossible to go past Van Gisbergen at the moment.
Dark horse: McLaughlin and Jamie Whincup should be right in the battle but Shell V Power driver Fabian Coulthard is just starting to show some signs of life.
Pressure on: Nissan Motorsport teammates Michael Caruso and Kiwi Andre Heimgartner might be battling for a drive next season in a two-car operation.
