The final practice session is complete at the Castrol Townsville 500 -Driven by TAFE Queensland, with ARMOR ALL Qualifying under an hour away.
Shane van Gisbergen topped the session, meaning the Kiwi has run quickest in three of the four practice runs yesterday and this morning.
The 1min13.25 lap bettered yesterday's fastest time of 1min13.70 - recorded by Lee Holdsworth - and led a list of charging Holden Commodores, with eight VFs making up the top 10.
"A few little tweaks overnight made the car much better on new tyres," fast man van Gisbergen told v8supercars.com.au.
"It's been great but we don't have any points yet, so we'll see what happens this arvo."
Holden Racing Team and last year's second placed Sunday finisher James Courtney was just 0.024sec adrift of the VIP Commodore, with Jamie Whincup, Tim Slade, Jason Bright, Volvo's Scott McLaughlin, Fabian Coulthard, Nick Percat, Garth Tander and the Nissan of Todd Kelly completing the top 10.
Yesterday's quickest, the Erebus Mercedes AMG of Holdsworth was in 12th, with the first Ford of the queue David Wall in 15th.
Others to note include Championship leader Mark Winterbottom in 16th, second placed in the points Craig Lowndes in 21st and Chaz Mostert 22nd .
