'I would never do that': Kostecki details 'malicious' Mostert incident

Shell V-Power Racing Team star Brodie Kostecki has offered more detail into his incident with Chaz Mostert, as fallout continues from the Christchurch finale.

In a move that has split opinions throughout the Supercars paddock, Kostecki was sent on one of the wildest rides of his career after being squeezed off the road.

The sent Kostecki careening through the infield, and back across the road into the path of Mostert and Lucky Dogs podcast co-host Will Brown, who both had to take evasive action.

Mostert was quickly slapped with a 30 second penalty, with the pair seen discussing the incident in pit lane post-race. Kostecki further expanded on the incident on his Lucky Dogs podcast.

Whilst Mostert pointed towards wheel to wheel contact being a contributing factor post-race, Kostecki disagreed, suggesting that he thought the move was in retaliation to a forceful move made by Kostecki at Turn 2.

He also stated that the hours of work crews put in to repairing cars are a big factor in why he wouldn't force others off the road, comparing it to when he made a mistake and harpooned Kai Allen at Bathurst last year.

"At the end of the day the picture is much bigger than just us as drivers. I would never do that [force another driver off the road] anyway, because they've got mechanics and people," Kostecki said.

"I'm one that thinks about all that stuff, when I drilled Kai's car ,the first thing I thought about was I could see his parcel shelf, I hit him that hard. I apologised to Al [McVean, Allen's then-Race Engineer]."

Kostecki also revealed that to the best of his knowledge, his move on Mostert had been cleared by Motorsport Australia officials.

He also admitted that the pair have a heated history on track, highlighted by a tense stoush last year at Taupō, that saw Mostert aggressively move by Kostecki for a race win.

"I could be wrong here, but I think the team went down and spoke to MA afterwards," Kostecki said.

"I believe they said my move was 100% clear, so they had no problem with mine whatsoever because I actually had a fair bit of overlap on Chaz.

"Chaz does race pretty hard, we always does race hard. I've had some pretty good battles with Chaz, but most of the time I end up with four wheels off the circuit on an exit.

"When I was down the inside, I ended up with two wheels on the grass."

Kostecki the went so far as to call the Mostert move 'malicious,' especially after on-track tensions with Mostert and Broc Feeney rose in a bumping duel in Taupō.

"We were side-by-side and he kept hip checking me, he was throwing his car at me to try and make me lose momentum or have to lift.

"There's a difference between hard racing and malicious manoeuvres. It's pretty clear, and I thought it was pretty malicious to be honest.

"I say this because it's the second time it's happened in two weeks, Broc down the straight [at Taupō].

"The incident happened, and the penalty came out two minutes after the incident happened. They did the 30 seconds straight away, so it can't be protested or anything afterwards, it's an in race judge of fact penalty.

"With the Finals stuff, it's pretty big."

The 2023 champion also maintained his big picture outlook on the scenario, which sees him looking ahead to the final day of the bp Adelaide Grand Final in Adelaide.

Despite losing the championship lead to Feeney, the #17 Shell V-Power Ford is still shaping as one of the key contenders for the 2026 championship, however Kostecki knows there is plenty of water to go under the bridge.

"Chaz come up to me afterwards, and he tried to contact me afterwards, he basically pinned it all back to Turn 2 the whole time," Kostecki said.

"I was like it's just retaliation I guess. He said I doored him hard and he went off the track, but I said to him that he thought I would be extremely disappointed. To be honest, I wasn't. I was annoyed, but I wasn't that disappointed.

"Obviously I was in the hunt for the JR Trophy, and we want to win that, but ultimately when I went back to the pits, I think Tom [Moore, DJR Team Manager] was the angriest out of everyone about it all.

"I said there's two ways we can look at this, we can worry about that, or we can worry about that we were fifth on road today. So we'll just focus on that."

The 2026 season resumes in Tasmania on May 22-24.
