Ashley Walsh emerged quickest from both practice sessions ahead of what promises to be a hotly contested third round of the Dunlop Series at Barbagallo.
“We made some changes between P1 and P2 to tune the car up for the green tyre,” said Walsh.
“We missed the boat a bit on the first run but a few tweaks and the second run was much better.
“I think we know what direction we need to go for qualifying.”
Having won the previous round at Winton, Walsh sits just 22 points behind series leader Paul Dumbrell heading into the opening Barbagallo race.
“I have always liked this track,” continued Walsh, who took out the Barbagallo round on the way to second in the final standings last year.
“I just seem to click with it and when the car is good we do go well.
“The Infants' Friend Falcon was great here last year and coming into this weekend the car has been quite good right from the start.
“I am looking forward to qualifying now.”
Walsh's rookie team-mate Todd Hazelwood was an impressive fourth in the second session ahead of Dean Fiore, Chris Pither, Dumbrell, Morgan Haber, Andrew Jones and Geoff Emery.
Joining the series in MW Motorsport's #27 Ford this weekend, Fiore missed the second half of opening practice after a collision with Dan Day's Holden.
Fiore was collected by the Holden as it exited the pits, bending his Falcon's differential housing.
In other Barbagallo support action, Ryal Harris led a Ford sweep of qualifying for the V8 Ute Racing Series.
Trent Young proved the pace-setter in the Aussie Racing Cars to take pole for the pint-sized class, edging out Maurice Masini.
Local Super GT and Historic Touring Car action completes the undercard, with the former category seeing a Ford Falcon BF V8 Supercar-mounted Matthew White out-qualifying the Alfa Sports Sedan of Tony Ricciardello.
