David Coulthard: I don't think we're suddenly going to take a big step forward here, but we're starting to get a better understanding of the car. Inevitably that will help with future development. I honestly don't know where we are in the field at the moment – tomorrow will tell.

Christian Klien: I went out in the first session for just a few laps. The car felt not too bad overall, although there was some understeer. I had problems with the brake balance and, as a result, the rears kept locking up. I wasn't able to adjust the balance from the cockpit, so that's why I was off the pace. In the second session, after we'd made some changes to the brake balance, the car felt better.

Robert Doornbos: That wasn't such a good Friday for us to be honest. Normally we have a better day, but we struggled with the set up this morning. The car was very unbalanced, so it was quite difficult to do the tyre work and the set up at the same time, but we made the best of it this morning. This afternoon we did some long runs, which were consistent and we have a clear decision on tyres for the weekend. It's a very particular circuit to get the right set up right here, and hopefully things will improve over the weekend.
