Supercars co-driver James Moffat has been banned from the final Porsche Carrera Cup race on the Gold Coast after an off-track altercation with a rival driver.
Moffat, who partnered with Ford's Chaz Mostert to win Saturday's 300km Supercars race on the streets of Surfers Paradis, got into a clash with Glen Wood during the opening race of the weekend for the support category earlier in the day.
The pair had a run-in on track before continuing their disagreement in the closed park area after the race.
Moffat has been fined $5000, half of which is suspended, after an investigation into the incident deemed him guilty of physical retaliation.
The son of Australian motorsport great Allan Moffat has also been banned from taking part in Sunday's final race of the Carerra Cup season.
The findings have no bearing on Moffat's partnership with Mostert, meaning he is free to race in Sunday's 300km Supercars event.
Wood was fined $500 after being found guilty of verbal abuse.
Reynolds snares pole for GC600 Supercars
Holden's David Reynolds will start Sunday's Gold Coast 600 Supercars race from pole position as he attempts to put Bathurst heartbreak behind him.
Reynolds, who had to relinquish the lead in the closing laps of the Bathurst 1000 earlier this month due to severe cramps, clocked a fastest lap of one minute and 10.6976 seconds to secure his third pole from the past four races.
"I was really happy. The car in qualifying wasn't the best and we went back to our set up we had yesterday and it transformed the car," Reynolds said.
"I'm so happy. It's so good."
Saturday race winner Chaz Mostert (1:10.7085) will start the 102-lap race from second with championship challenger Shane Van Gisbergen (1:10.7148) third on the grid.
Championship leader Scott McLaughlin will have to start from eighth after he was one of three drivers disqualified from the shootout due to kerb-hopping on their flying lap.
McLaughlin, defending champion Jamie Whincup and Holden's Tim Slade were all scratched from the session for cutting the kerbs on the 2.96km street circuit.
"Mistake on my part," McLaughlin told Fox Sports.
"Sorry to everyone at Shell V-Power Racing but I think we've got a little hot rod today so see how we go."
McLaughlin's fifth-place finish on Saturday has given him a 14-point lead in the championship standings over Van Gisbergen.
Whincup and Slade will start from ninth and 10th respectively.
Sunday's race starts at 2.25pm AEST with the possibility of an afternoon storm making drivers sweat on their race strategy.
"We're sitting there hoping it doesn't come because our car is awful to drive in the wet," Reynolds said.
