Broc Feeney has turned the tables on Triple Eight teammate Angelo Mouzouris to register his maiden Dunlop Series victory at Mount Panorama.
A forceful overtake at Turn 1 was key to Feeney's success, with the teenager pressuring pole man Mouzouris from the get-go.
Mouzouris made his #10 pitbox.io Commodore as wide as it could be in the early stages, leaving Feeney with little chance of an overtake.
On the fourth lap, after three laps of robust defence from Mouzouris, Feeney made his move stick.
It came following an error by Mouzouris on lap 2, with the polesitter straight-lining the run-off at Skyline heading towards the Dipper.
The mistake bunched up the pack, with Jayden Ojeda fortunate to avoid damage in contact in side-to-side contact with Matthew McLean at Turn 1.
Aaron Seton, Tyler Everingham and Steven Page failed to finish the shortened eight-lap race, with Everingham failing to make the start after his car stopped out of place en route to the grid following the warm-up lap.
Seton's car shut down on him, with the Matt Stone Racing driver pitting at the end of lap 4.
By race's end, Feeney enjoyed a 3.1s lead over Mouzouris, with Jordan Boys holding on for third.
Zak Best impressed for Tickford Racing with fourth, with Ojeda beating McLean to fifth.
"I'm lost for words," said Feeney, who claimed Triple Eight's first win in the development series.
"It was great, what a way to start the championship.
"The car looks unreal, I look so comfortable in it, and I think that's what's making us go fast.
"I don't have to push literally as hard as I can, I just make sure I hit my marks, and I ended up with my first race win, and Triple Eight's first win in Super2."
