MW Motorsport's Zane Goddard completed a sweep of Dunlop Super2 Series ARMOR ALL Poles at the PIRTEK Perth SuperNight.
Goddard, who took pole for the opening race on Friday at Barbagallo Wanneroo Raceway, was the class of the field again in ARMOR ALL Qualifying on Saturday.
He put in a 54.9154s towards the end of the 15-minute session, with a final margin of just 0.0571 seconds over Matt stone Racing's Ash Walsh.
The second-year Super2 Series driver is yet to finish off the podium in the 2019 season.
After taking his maiden Super2 victory on Friday, Will Brown set the early pace with a 55.2292s and held onto top spot until the closing stages.
Brown's Eggleston Motorsport team-mate Dean Fiore was the first to displace him and went 0.0808s quicker.
Moments later, Walsh was the first into the 54s barrier, taking the lead with a 54.9725s, before Goddard fired through with a 54.9154s.
From there, Goddard remained at the top, with Walsh second and Goddard's MW team-mate Bryce Fullwood third.
"I'm blown away, that one was definitely a more hard-fought one," Goddard said of his back-to-back pole positions.
"First lap on the older tyres, I really struggled a little bit, so we chucked the new ones on and that was pretty good.
"There was a little bit of traffic again, I was a little bit worried, but we did enough to get P1.
"I'm super stoked today, the team has done an awesome job and I can't thank them enough."
Triple Eight's Kurt Kostecki will start Race 2 from fourth on the grid, ahead of his cousin Brodie Kostecki.
Fiore eventually finished the session sixth, ahead of Jack Smith, top rookie Tyler Everingham, Brown and Adam Marjoram.
Tickford Racing's Thomas Randle was 11th, from Jake Kostecki, Brenton Grove and Jordan Boys.
The second and final 26-lap race of the weekend will commence at 5:15pm local time.
