US Friday quotes: Red Bull

"We might have lost a little bit of info regarding the car's set-up, which is one of the things you use the third car for. Other than that, there's not a great deal to say about the session. We had some oversteer and in trying to balance it out we took out more and more front flap to try and cam it down, but I think we went a little over the top."

Christian Klien - 20th: "There's a very long straight in Indy, which is good fun, but the infield is a little slow to drive. I did two runs in the second session and the circuit had very low grip. It was quite difficult to get the balance right and the car had some understeer, so we'll have to look at what we can do to improve it for tomorrow.

"I hope we can do a good race for the fans here; last year was a bit of a disaster. But, Michelin is looking after the fans really well and I think they've bought a good tyre here, so we should see a very good race on Sunday."

Robert Doornbos - 26th: "It didn't work out too well this morning, as we struggled with the set up of the car. We did our homework in between sessions and I worked with the engineers to try and improve the car, which was important for the long runs in the afternoon.

"In the second session we started the first long run, but after a couple of laps we had a gear box failure so it was a very short Friday for me. I hope it's the first and the last!"
