The Team BOC driver improved his second sector, over the top of The Mountain, by 0.3s.
Last minute changes meant that Jason Bright did not know what to expect on his Shoot-Out lap at Bathurst today but his faith in the new set-up paid off with third-fastest.
The Supercheap Auto Bathurst 1000 will start at 10.30am after one final warm up.
Jason Bright: "We went into the shoot-out with more changes than I would have liked but it was my quickest sector over the top by a mile. I had to put a fair bit of faith in the car but it felt great.
"It wasn't the best lap I've ever done. I wasn't happy with Turn One and it was my worst run up the hill but the rest of the lap was really strong. I knew if Jamie [Whincup] did a good job he would pip us so I'm just glad to be starting third. We've got similar pace to him though for the race. Race pace is a very different story to one lap.
"Jamie was on top of his game and did a great job today. Hats off to him but I think it's going to be a great race tomorrow. There are a lot of guys in contention. We have to make sure we're there at the end with a strong car."
