Jenson Button was reasonably happy following practice on Friday for Sunday's Italian Grand Prix, despite admitting that they still have a lot of work to do.
Button is desperate for a good result this weekend and will be looking to get his championship challenge back on track, after less than successful outings in Britain, Germany, Hungary, Spain and Belgium.
Despite his poor run though, the Englishman still leads the race for the 2009 F1 drivers' championship by 16 points and while he was only 19th in second practice today, he was seventh in the first session and finished the day tenth on the combined timesheets, his best effort a 1m 24.706s.
"We did a lot of set-up work today with the car in the low downforce configuration although we had a couple of issues which meant that I couldn't do the long runs that we had planned so that was a bit frustrating. Everything was sorted out by the end of the day which is good but we have a lot of work ahead of us," Button noted.
"It feels very different running with such low downforce but the car has been performing reasonably well. We need to work on the fine-tuning of the set-up overnight to ensure that I'm completely happy with the balance before qualifying."
Button's Brawn GP team-mate, Rubens Barrichello meanwhile was twelfth fastest in FP1 and 16th in FP2, his best a 1m 24.826s, which left him 15th on the combined leaderboard.
"Our programme went pretty much as planned today with the performance of the car as we were expecting," Barrichello continued.
"Our set-up work was focused on long runs and I'm fairly happy with how the car feels and with the braking stability. We have some work to do on the balance but overall a good start to the weekend although today's running doesn't really give us an indication of how qualifying will play out tomorrow."
"With Monza being such a unique low downforce circuit and the fact that we haven't had the opportunity to here test this year, today's practice sessions were particularly important to work on the set-up of the car," added team boss, Ross Brawn. "Our main focus has been on race preparation to ensure that we understand how the car feels with the low downforce. We're reasonably happy with our progress over the course of the day and looking forward to the weekend ahead."
