Supercars championship leader Broc Feeney will leave Perth with a pair of victories after a near-flawless display in the final sprint race.
Triple Eight ace Feeney survived late drama as he led from start to finish across the 83-lap, 200km race at Wanneroo Raceway on Sunday.
It was the 22-year-old's fifth win of the season, adding to his haul of six poles and eight podiums.
A safety car with 20 laps remaining threatened to cause chaos for Feeney.
The first yellow flag of the weekend was brought out when Erebus rookie Cooper Murray came to a halt on the way to turn six after a suspected mechanical failure.
It set up a re-staging of Feeney's showdown with Matt Payne in Tasmania, where the Grove Racing driver won by just 0.0550 seconds.
Feeney was unwilling to lose to Payne again and he flaunted blistering pace to win by 0.5671 seconds.
"To have the race like we did there, it was pretty - I shouldn't say smooth sailing - but a lot less stressful than it was at the end of the race," Feeney said.
Triple Eight team principal Jamie Whincup couldn't say the same.
"I was having deja vu, it's going to happen again," Whincup said.
"I was just out front yelling ... I was having nightmares."
James Courtney was the biggest beneficiary of the yellow flag, crossing the line third after qualifying 13th.
It was a surprise podium for one-time Supercars champion Courtney, whose best result this year in the Blanchard Racing Team car was ninth in Tasmania.
It is also Blanchard Racing's maiden podium since the team's entry in 2021.
"I got so emotional," Courtney said.
"It was me crying for a third."
Tickford star Cam Waters was unlucky to finish fourth after starting in the first row with Feeney.
Ryan Wood, after breaking through for an emotional maiden Supercars win the day before, had been as high as second before being ruled out of the race after a tangle with James Golding.
PremiAir Nulon Racing's Golding had run wide at turn one with eight laps to go, allowing Wood to move into fifth.
But Golding was determined to regain his spot and ended up running both cars off when they collided side-on.
Golding, who finished 22nd, was slapped with a drive-through penalty for the incident.
Reigning champion Will Brown was fifth after another hairy moment with Golding early in the race.
Golding had been fourth and assertively defending his position when the nose of Brown's Triple Eight car hit his right rear and sent him wide at turn seven.
Meanwhile, Wood's teammate Chaz Mostert was sixth after qualifying in 14th.
Local product Brodie Kostecki was 11th after his hopes of a home victory were dashed when a poor qualifying effort condemned him to 15th.
Cam Hill, after qualifying seventh, endured a nightmare start when his Matt Stone Racing car stalled at lights out.
Suffering a battery issue, his car had to be towed back to pit lane.
Hill was able to join the race and finished last.
