SHANE van Gisbergen will lead the charge in the Top End after heading Friday's final V8 Supercars practice session in Darwin.
On a day where form was hard to judge as teams sought to learn as much as they could on old tyres, Van Gisbergen was quickest of all when the brand new Dunlops were bolted on as the end of the session neared.
The Holden driver's 1m09.3476s lap headed Jamie Whincup, who set his good-tyre lap early, with James Courtney the only other driver to lap the Hidden Valley circuit in under 1m10s.
Rick Kelly followed up his Nissan teammates' session-topping effort earlier in the day to be fourth, ahead of Russell Ingall and Michael Caruso.
The Volvo twins were next, Robert Dahlgren ahead of Scott McLaughlin this time despite the Swede's car being pitbound for much if the session with an electrical issue.
Championship rivals Craig Lowndes and Mark Winterbottom rounded out the top 10.
Fabian Coulthard, third in the championship and fastest this morning, ended the day down in 20th sandwiched by Brad Jones Racing teammates Jason Bright and Dale Wood.
Saturday will see the V8s hit the track for two 10-minute qualifying sessions near midday ahead of two 100km-long races.
PRACTICE 2
NISSAN took a one-two sweep thanks to a string of late flyers from James Moffat and Todd Kelly.
Craig Lowndes headed most of the session until several cars opted to switch to soft tyres, with first Scott McLaughlin then the Nissan duo bettering his time.
Kelly initially held the top spot, only for Moffat to edge him with a faster lap as the chequered flags flew. Kelly was quicker again through the opening sectors of his final lap, but was unable to improve on Moffat's mark.
McLaughlin's Volvo was next ahead of Jamie Whincup and Lowndes. The Erebus Mercedes were next, Lee Holdsworth ahead of Will Davison, after the pair had sat in positions two and three ahead of the final flurry.
Jason Bright, this morning's fast man Fabian Coulthard and Moffat's Nissan teammate Michael Caruso rounded out the top ten.
Championship leader Mark Winterbottom ended the session in 15th, right behind all three of his Ford Performance Racing teammates.
Tyre conservation was the name of the game down at the Holden Racing Team, with Garth Tander the best of the four Walkinshaw cars in 18th with just six laps to his name, ahead of teammates Tim Slade and James Courtney who logged just two each.
Drivers were reporting that the track was becoming slippery as the high midday sun beat down on the circuit, with temperature playing a major role in the amount of grip on offer from the tarmac.

PRACTICE 1
FABIAN Coulthard has topped the opening session of V8 Supercars practice ahead of this weekend's SkyCity Triple Crown in Darwin.
The New Zealander lapped the 2.41km Hidden Valley circuit in 1m10.5465s, marginally quicker than James Courtney and teammate Jason Bright who filled out the top three, the trio split by just 0.0523s.
"We bedded brakes in the first part (of the session), put on our used tyres and away we went," Coulthard told v8supercars.com of the session.
The hot conditions combined with a dusty first-day surface yet to be bedded in with rubber, leaving most drivers struggling for grip.
"That's standard," Coulthard explained. "We're all in the same boat. We know where we get here it's going to be slippery, high ambient – it's definitely a recipe for a lot of cars to be sliding around."
Jamie Whincup made it an all-Holden top four ahead of Will Davison in the first of the Erebus Mercedes and Scott McLaughlin in the leading Volvo.
Championship leader Mark Winterbottom ended the session in seventh, with Scott Pye, Shane van Gisbergen and Todd Kelly rounding out the top 10.
Title rival Craig Lowndes was quickest early, but was unable to improve on his early lap as he and others chased the right setup for the hot and slippery conditions.
After also sitting inside the top five early, Russell Ingall was forced to the garages so his crew could fix an oil leak in his Holden's transmission.
Tyre preservation will be the other main focus for teams today as they do their setup work on just two pre-used sets of tyres, with an additional brand new set of Dunlops likely to be saved for a qualifying simulation run at the end of the day when the track is at its best.
