David Wall has recorded the top time in the first practice session at the UBET Perth SuperSprint.
The Volvo S60 driver has inherited Scott McLaughlin's chassis for this event, while the Kiwi moves into a new car. There were no gremlins for Wall despite the team's recent engine issues, as he recorded a 57.12sec lap in the closing stages of the session on soft Dunlop tyres.
"The car is new to #34, but it was #33 for a while," Wall told v8supercars.com.au.
"The boys have done a great job of moving all my gear inside of it and pretty comfortable straight away. It feels good.
"I topped the session -I've never done that before, which is quite cool!
"In saying that we had a soft tyre on at the end, but even on the hard we were still sort of top 10 or 11 on the second-hand hard.
"The soft was more about a longevity run rather than getting a time -so I never expected to be P1!"
Wall recently missed the Australian Grand Prix showcase event after serious burns to his foot at the Clipsal 500. He had a skin graft in the lead-up to Perth, and is well on the way to recovery now.
"[Topping the session]was cool and a very good way to start after the break ... I'm off the crutches and all good.
"The foot's still a little sore, but definitely better. The next meeting will be better again, we have a bit of a break and then by Darwin hopefully 100 per cent."
The session was red flagged with minutes to go as Nick Percat's LDM Commodore was beached at turn one.
Until then Red Bull's Craig Lowndes - looking to crack 100 wins this weekend -led the session. He finished second, just 0.16sec behind the Volvo.
There was a close call in pit lane between James Courtney and Jamie Whincup, with the HRT driver swerving to avoid the Red Bull Commodore as drivers filed out to make the most of the last remaining minutes when conditions turned green.
Mark Winterbottom was third in his FG X, with Courtney and McLaughlin top five.
A number of additional drivers spent time behind the wheel that session, with the Courtney/Jack Perkins combination the best placed on the timesheet.
