The #1 Red Bull Holden of Jamie Whincup and Paul Dumbrell topped all four Friday practice sessions at the Armor All Gold Coast 600.
Whincup completed the sweep by edging out the Holden Racing Team’s James Courtney in Practice 4.
The Holden duo swapped the top spot between them throughout the 40 minutes, with Whincup eventually setting the best time of 1:10.28s on his final lap.
Courtney improved on his final flyer but fell 0.17s short, while David Wall was a surprise third in the Wilson Security-backed Brad Jones Racing entry.
David Reynolds, Michael Caruso, Will Davison, Shane van Gisbergen, Tony D’Alberto, Garth Tander and Alex Davison completed the top 10.
Usual front-runners Craig Lowndes and Mark Winterbottom ended up just 18th and 22nd respectively.
