Triple Eight driver ceded points lead to teammate Will Brown

Broc Feeney was left "spewing" after a costly mistake, caused by his foot slipping off the brake pedal, cost Red Bull Ampol Racing a one-two in Race 4.

Thursday winner Feeney entered Friday two points ahead of teammate Will Brown, who took the lead from pole-sitter Cam Waters off the line and won the race.

Feeney passed Waters for second, and the two collided at Turn 12. Waters dropped to sixth, while Feeney managed to regain second from Mark Winterbottom.

Late in the race, as Brown consolidated his lead, Feeney set up for a crack at the fastest lap, only to make a mistake at Turn 13 and drop behind Winterbottom and Matt Payne.

Feeney lost nine points to Brown with the mistake, and was frustrated to throw away a third Triple Eight one-two in four races.

“I got a good start today which I was really happy with. Will got Cam and I tried to get through, but sort of settled in for a bit before I got him a bit later,” Feeney said.

I tried to look after my tyres for a bit throughout the race but then I realised I needed to pounce on Cam, which I did but then I dropped behind Frosty [Winterbottom].

"There were a few laps there where I had to use a bit more of my tyres than I would’ve liked, but then I settled in for the long run.

"I was following Will around trying to save our tyres like he was, and as it got to the end of the race, I went to go for the fastest lap but a few corners before I started my lap, my foot fell off the brake pedal and I made an error.

"I’m spewing for the team because it would have been another solid result, but you’ll take the little loss here and reset for tomorrow."

A potential nine-point lead became 18 for Brown, with Chaz Mostert now 83 points down after a Todd Hazelwood hit triggered a fall to 17th.
