The fitting marked the first time the former had sat behind the wheel of an F1 car since he left Ferrari at the end of the 2009 season.
How important is the seat fitting?
It is one of the most important jobs. You spend so much time sitting in the car so the position is really crucial, it needs to be 100% right. I’d rather spend a lot of time getting it right at this time of the year because there are many races in the season and you sit behind the wheel a lot. Getting it right the first time is imperative.
