Mostert beats Davison, Brown in final Perth practice

Saturday winner Chaz Mostert has set the pace ahead of all-important Boost Mobile Qualifying in Perth, topping Practice 3 on Sunday morning at CARCO.com.au Raceway.

Walkinshaw Andretti United star Mostert, who won his first race of the season on Saturday, set the only 54.0s lap of the 20-minute session.

The Ford star, however, was only 0.0586s faster than Will Davison, with championship leader Will Brown 0.0924s down in third.

Broc Feeney and Brown set the early running, Feeney clocking a 55.5164s, followed by Brown’s 55.5360s. The teammates pressed on, Feeney recording a 55.1286s, and Brown a 55.2631s.

Behind the teammates, Matt Payne (55.4876s) led Brodie Kostecki (55.5562s) before the balance of the field came into the lane. Off sequence, Richie Stanaway jumped to third with a 55.4254s.

Cameron Hill jumped to third with a 55.3072s, before Matt Stone Racing teammate Nick Percat jumped to fourth with a 55.4057. All the while, WAU hadn’t fired a shot — Mostert was 16th, and Ryan Wood 23rd, at the halfway mark.

Davison, who was undone by an electrical issue in Saturday’s race, powered to second with a 55.2558s, before improving to first with a 55.1189s on his second push lap.

Mostert then began to show his speed, jumping to the top with a 55.0818s, before turning in the firs 54.0s lap, a 54.9868s, on his second lap.

Brown jumped up to second with a 55.0792s, and was just 0.0924s behind Mostert’s benchmark. Through 13 minutes, the top eight cars were covered by just 0.27s.

The majority of the field came in for a second time — before they returned to the track, Randle moved to third with a 55.1135s with six minutes remaining.

With four minutes to go, Wood still hadn't set a representative time, instead giving WAU an opportunity to get valuable four-tyre stop practice, with the Kiwi rookie 24th and last of all drivers.

Wood pressed on late in the session, but struck traffic into Turn 6, with the New Zealander forced to take evasive action. On his next lap, Wood vaulted to fifth, with Mostert getting out of the car in the closing minutes.

After 20 minutes, Mostert, Davison and Brown were covered by just 0.09s, with Thomas Randle, Wood, Feeney, Anton De Pasquale, James Courtney, Payne and Hill rounding out the top 10.

Supercars will return to the track on Sunday for knockout Boost Mobile Qualifying at 12:00pm AWST/2:00pm AEST. The second 55-lap race of the weekend, Race 10, will commence at 3:45pm AWST/5:45pm AEST.
