"Obviously Triple Eight had turned up with a pretty good package and we tried to trim our car out a bit, but that changed the front braking stability and tyre wear; all our cars struggled that weekend.
"It was pretty hard to watch the Triple Eight cars on the straight [Sandown] just go past us.
"I hope we don't fall into that trap this weekend at Bathurst of chasing the Triple Eight cars."
The Bathurst 1000 is race all of its own with huge elevation, incredible speed, concrete walls and a heap of history and mystique. A little bit like the Indianapolis 500, there are some drivers who would rather win that one race that a championship.
Visually there is nothing like the Mount Panorama circuit anywhere else on the Supercars race calendar, so it just might be the most difficult track to set a car up for.
"All circuits have their unique challenges. Sometimes you think a car looks pretty good [on track] and then you look at the time sheets and you're nowhere. At Bathurst obviously you have to have everything going for you.
"The biggest thing for Bathurst is to have the drivers confident in the car and that it's predictable for them. A lot of the lap time comes from them being confident that the front and rear are going to stick when they tip it in — especially across the top of the hill.
"You have to make sure the car is quick as possible as most of time the drivers are full throttle. You can be a bit slower across the top as it's hard to pass up there, but once you get to Forrest's Elbow the car has to be fast or you'll passed down Conrod Straight.
"We can't take too much aero of or the car becomes too pointy. We're going to change a few parameters too, so if we do trim the wing out the car will still be stable. If we do it right at the start of the weekend the drivers can used to it so they don't get a surprise with the change of grip."
As mentioned earlier, qualifying didn't go so well, but tomorrow is another day as they say. Some teams may be short odds with book makers, however, for those who have watched this race over the years it would be churlish to pick a winner solely on the season's form so far. Winterbottom and co-driver Dean Canto have both got good pedigree so could just be the outsiders to sneak a win while nobody is looking.
