Jenson Button gave himself and his BAR team the perfect boost today, by> breaking the unofficial lap record at the Circuit de Catalunya. To put> the icing on the cake, on a day in which the team completed over 261> laps of the Spanish track, teammate Takuma Sato was third quickest,> albeit 0.695s off the pace.> The Englishman, running the aero package that the Brackley outfit is> expecting to run at Imola, had a trouble-free day, giving the> under-fire team a much-needed fillip before the start of the European> season.> Jenson spent the morning continuing his aerodynamic evaluation,> alongside a suspension test. In the afternoon he concentrated on> fine-tuning the car alongside some chassis set-up work. Later in the> day, once Sato had finished his programme of tyre evaluation with a> series of longer runs, and therefore not breaking the agreement whereby> teams only run two drivers, Enrique Bernoldi ran a number of shakedown> laps.
