Despite an engine change pre-qualifying Fabian Coulthard still struggled to reach top speed on Bathurst's two long straights today, finishing 14th fastest.
The Top Ten Shoot-out begins tomorrow at 5pm.
Fabian Coulthard: "We just had no grip today. We ran other tyres in the practice session before and basically, relative to that session, it felt like a different car in qualifying. It's so close though, which leaves you feeling uncertain, but at least it's a long race on Sunday.
"We're struggling for straight-line speed. We changed the engine before qualifying and it doesn't seem to be the fix. We've obviously got another issue but we're still a bit unsure about what it could be. Maybe drag. With two long straights in this place you don't' need to be down much and you're right down the order."
