IRWIN Racing's Lee Holdsworth and Craig Baird have enjoyed a productive opening day of practice for this year's Supercheap Auto Bathurst 1000.
At the wheel of the Mercedes-Benz AMG E63 V8 Supercar from Erebus Motorsport, Holdsworth did the majority of the running in the opening 45-minute session to be 11th on the time sheets.
The final practice was a stop-start affair with three separate stoppages for incidents on the track. Fortunately none involved the IRWIN Racing entry, but a heavy accident to Erebus team-mate Tim Slade will require major repairs. Slade was no injured in the accident.
Holdsworth completed the final session with the seventh fastest time to round-out a solid day for the IRWIN squad.
Another busy day lies ahead for the team with two separate practice sessions, including another dedicated 45-minutes for Craig Baird, before qualifying at 3pm.
