Macauley Jones put down the fastest lap in Practice 2 for the first round of the 2018 Dunlop Super2 Series at the Adelaide 500.
The Brad Jones Racing driver turned a 1:21.5704s during a late run on green tyres to shade 2016 series winner Garry Jacobson.
Jacobson was the first to drop into the 1:21s barrier and held onto top spot into the closing stages.
Jones, though, produced a pair of quick laps late to move into second and then shade Jacobson by just 0.0609 seconds.
MW Motorsport enjoyed a strong session, with Jacobson followed by Dean Fiore in third place, while Alex Rullo finished eighth.
Jake Kostecki and Shae Davies made up the top five, ahead of Tickford Racing’s top rookie Thomas Randle and Brodie Kostecki.
Garry Rogers Motorsport’s Super2 returnee Chris Pither and Jones’ BJR team-mate Jack Smith rounded out the top 10.
Paul Dumbrell set the early pace but didn’t improve thereafter and fell to 12th in the order, one spot behind Eggleston Motorsport team-mate Will Brown.
ARMOR ALL Qualifying will take place at 1:20pm local time on Friday at the Adelaide 500.
