Team owner Brad Jones has confirmed that the rear chassis rail has been damaged but is optimistic that repairs can be completed today.
The biggest concern at the moment is securing a replacement roof panel.
“No, it's not great way to start the day. It's repairable and I'm hoping we'll get it back out today,” Brad Jones told Speedcafe.com.
“We're just pulling it apart now, so it's a bit hard to tell. It's damaged the rear rail, but you know, we need to see how we go.
“We've got most of the bits and pieces here for it, the roof is the only concern. We're working on that at the moment.”
Macauley Jones, who is sharing the car with Dean Canto, believes the damage looks worse than it is in reality.
“I just lost the rear,” said Macauley Jones.
“The track is very loose at the moment. We just made a change, went back out and it definitely didn't help it.
“It didn't feel like it went in that hard, just slowly lost the rear and then tapped it,” he added of the impact.
“It looks a lot worse than what I think it is, there's no suspension damage, just panel work really and for some reason the roof took a lot of it.”
