Under threatening skies that never delivered any rain until the cooldown lap, the duo locked into 1-2 formation from about half-race distance as any challengers dropped back.
It enabled Brown to take his third win of the season after forcing his way past his team-mate with eight laps to run.
“I was trying not to use the front bar, awesome racing, that is what it was all about,” said a smiling Brown after coming out on top of a tense battle.
“I locked the rears and I just got around. I might have touched him once, it was hard to resist. That was the best race of my life!”
“We put on a good show for the crowd,” said Feeney, who started second on the grid.
“Will had a lot of speed today. Wet conditions, we were learning, we learned a lot, The main job was to do a reset and get on with it today.”
