Amid speculation about his future, James Moffat has risen to the top of the times in the final practice session at the Castrol Gold Coast 600.
The Nissan driver recorded a 1min10.7995 lap around the Surfers street circuit in the final stages of the session.
"Great effort by the team, car's pretty strong on both tyres - obviously we're on the soft tyre there at the end but so were quite a few others," Moffat said.
"I'm really impressed what we did there because Taz [Douglas, co-driver] did a long run in his co-driver session so we definitely used the best of the soft tyres.
"When they're hooked like that they're good fun to drive but it's only Friday so hopefully come back and do the business tomorrow.
"Everything's straight at the moment, keep it like that we'll be alright."
Moffat and Douglas earned a podium finish together at Bathurst last year and teammates Michael Caruso and Dean Fiore were on the podium at the Gold Coast this year.
The practice session was interrupted midway with the red flag appearing so a kerb could be repaired.
Sitting on top for a time but ultimately finishing second, Shane van Gisbergen enjoyed flying over the kerbs on the street track.
"It feels like rallycross down the back straight - you feel like you're higher than you look in the replays!"
He described his TEKNO Commodore as fast and consistent.
Meanwhile the drama continued for Red Bull's Jamie Whincup after the team elected to change the transaxle between sessions, attempting to fix a vibration in the car. He ended the session 24th.
Cameron Waters - who replaces Chaz Mostert - was also down the order finishing 21st.
Scott Pye and James Courtney returned to their drivers' seats for the session - Courtney hitting the wall at the end of the run - and while Pye admitted being sore at the end, he will be pushing to drive the race car tomorrow.
