Bright and Jones have one final warm up session to fix their issues before gridding up 11th for tomorrow's Sandown 500.
Mechanics are going over the Team BOC Commodore with a fine toothcomb this evening after Jason Bright reported something broken at Sandown today.
Bright, who qualified tenth this morning, handed the car over to endurance co-driver Andrew Jones for the first of two 20-lap qualification races.
Bright gained three spots during his qualification race courtesy of team mate Fabian Coulthard's battle with Alex Premat. He could not make up any more, however, and says the car's handling was the worst it has been all weekend.
Bright and Jones have one final warm up session at 11.05 to fix their issues before gridding up 11th for tomorrow's Sandown 500 at 13.35.
Jason Bright: "There's definitely something broken on the car. I reckon we damaged it this morning in practice and we've been dealing with it ever since. I've not had this many problems with handling for as long as I can remember. Even yesterday the car wasn't this bad!
"I think our pace is alright but we're used to being one of the quickest out there now. I think there's time in it and we need to find it tonight because it's not easy to pass around here. There are pit stops that will help but it's going to be hard to pass on track that's for sure."
Andrew Jones "I was right on the defence from the word go. We were weak throughout the whole race to be honest.
"With the Bairdo incident, it was pretty tight going in there and I covered but had no rotation at the apex. I knew he was there and gave him room but he was way too shallow and we obviously made contact. We lost three spots out of it but all I really wanted to do was get to the end so we could tune it and give Brighty a better shot at it. "
