Car #1 was dropped from its jacks and released from its pit box without a right-rear wheel as the result of a miscue during a practice pitstop.
Erebus CEO Barry Ryan explained that the team had been slow in making a setup change on the Brodie Kostecki/Todd Hazelwood entry, which led to the car being sent early.
“They were practicing a change for the race and it took longer than the driver [change], which caught out the car controller,” he said.
“He said ‘drop the car’ and the change wasn’t actually finished. It’s just a procedural thing we’ll fix, it’ll be fine.”
The Sandown 500 is set to take place from 2:05pm local time.
