Changeable weather conditions are the norm at Spa: After the first 90 minutes of free practice for the Belgian Grand Prix were wet, the track was dry for the afternoon’s session, and there was even some sunshine.

The BMW Sauber F1 Team managed to compress the usual Friday programme into the second session and all in all enjoyed a trouble free day with regular driver finishing well ahead of his German teammate in eighth place overall.

“The conditions today were quite changeable,” Kubica said. “We started the first practice session on dry tyres, but it started to rain pretty soon as actually we were only able to do one timed lap on dry tyres at the start of the session. We took advantage of the weather conditions and did a couple of laps on full wet tyres just to see how the car behaved in case of rain. We had to squeeze quite a lot into the second free practice session, and on top of that we evaluated the tyres and worked on the set-up. It was quite difficult as we had to cram several things into a very tight programme. We even had to mix several evaluations in one run. We also have a couple of new components on the car.”

In the afternoon the Hinwil based squad concentrated mostly on tyre comparisons and they still have quite a lot of work to do on the set-up of the car, because it is particularly important for the drivers to feel confident on this demanding track. The second sector, with its quick corners, is the most important one and this is what they have to focus on.
