At times it was slow a process for Jenson Button today with changes made to the McLaren MP4-28.
The team then elected to carry out some larger mechanical changes over the lunchbreak, meaning Jenson didn't return to the track until 3pm. Thereafter, he focused on longer runs with a number of simulated pitstops.
What’s next : The team plans to conduct more aero work tomorrow if the weather stays fine. However, with rain forecast for the whole day, our plans may change and we could well end up running Pirelli’s 2013 wet-weather compounds for the first time.
