DJR Team Penske's Scott McLaughlin did it again on Friday when he topped the times at the end of the first day of play for this weekend's Sydney Supersprint here at the Sydney Motorsport Park.

The young Kiwi finished second in opening practice before topping the timesheets in a near lap record time late in the final session.

He and his engineers worked on race set-up, before the qualifying switch in Practice 2.

They took green tyres, and had a very solid gain.

He is on the verge of winning the ARMOR ALL Pole Award for 2017, if he takes pole today he will be unbeatable with 10 races remaining.

“We've got another practice tomorrow, but we've got a good read on the tyres,” he said. “We got through everything we wanted to and It's a nice feeling to be up the front. Starting up the front means we can gain points, and keep moving forward which is vital to our championship. We need to convert this pace in qualifying tomorrow, and then see how we go.”
