Mark Winterbottom was fourth quickest in Friday practice after a strong day of progress for the IRWIN Racing Commodore at the Adelaide 500.

Practice 2 saw Winterbottom 10th as the team fine tuned their race setup for the weekend.

In Practice 3, Winterbottom’s 1:19.6055 on his final lap saw him climb from 12th to fourth in the times.

The IRWIN Racing driver’s top ten practice positions mean he automatically progresses into a second reduced segment of Qualifying for Race 1 on Saturday and Race 2 on Sunday.

Qualifying will be held at 11:55am local time tomorrow before the Top Ten Shootout and the first of two 250km races of the Adelaide 500 at 4:20pm.

“The goal was to get in the top ten in both practice sessions given this weekend’s qualifying format where we go straight through to Q2 tomorrow so overall I’m rapt,” said Mark Winterbottom.

“We cut it very fine in Practice 2 in 10th ,which is as close as you want to get, but to then get fourth in the second session with a 1:19.6 is a great confidence booster for the team.

“We’ve made good progress today, the team are now focussed on Scott Pye’s car to fix that after he was unlucky with a component failure today, and I think he would have been up there as well given his earlier speed.

“We’re pumped to go racing tomorrow.”
