After topping the time sheets in Thursday's practice for the opening round of the 2020 Supercar series in Adelaide, Albury's David Reynolds could only manage sixth fastest in Friday's first session.
However, he was only two-and-a-half tenths of a second behind leader Shane van Gisbergen.
A late red flag saw all cars head to pit lane with seven minutes left on the clock due to Scott Pye finding the wall at turn seven and the recovery vehicles needing to remove it.
With nearly all cars on fresh tyres and on their hot laps, it was bad timing for those looking to improve.
Brad Jones Racing's Nick Percat was hoping to move into the top 10 having been eigth on Thursday, but ruined his hot lap with a mistake at the final corner.

BJR boss Brad Jones was disappointed in not having at least two of his runners at the pointy end of the field.
"That's an understatement," Jones quipped when asked if thought his cars had showed more promise than their positions indicated.
"These sessions are very frantic when you are just looking for one quick lap.
"I felt like we should have a quicker. I don't think one of them is happy with their car, so we clearly have some work to do.
"Even for Nick, the top ten is a fair way away, so we have work to do."
Jones was loath to blame the warmer conditions but said it didn't help their cause.
"It is a bit warmer than yesterday (Thursday), which has never been good for our cars, but there's definitely more to it than that," he said.
"We'll spend the next few hours analysing things with the drivers and hopefully come up with some answers for the rest of the weekend.
Meanwhile, Reynolds said whilst he was P1 on Thursday, his car was a handful.
"Thursday my car was amazing, straight out of the gate I had a ball," he said.
"It was difficult though, like it wasn't to drive, I was battling everywhere, heaps of oversteer, but it's a lot of fun.
"I think maybe we settled it down just bit too much for today (Friday) which may cost me a couple of tenths, but we're not far away.
"The races here are long so I'm happy to be up the front anywhere for the start and just go from there."
There are two 250-kilometres races today and tomorrow around the fast but tight 3.1-kilometre Adelaide street circuit.
