Adrian Sutil has highlighted improving the balance of his Force India on the supersoft tyres as the one area he needs to focus on before qualifying.
Having spent a year on the sidelines, Sutil was quickly back up to speed as he finished ninth quickest in Friday's practice for the Australian Grand Prix.
The 30-year-old posted a 1:27.435 in Practice Two to finish 1.5s behind pace-setter Sebastian Vettel. However, more importantly, Sutil was also nine-tenths up on his team-mate Paul di Resta.
"It was a very good day and I feel satisfied," said the German.
"The baseline set-up was not too far away from what we needed and the car felt very similar to the way it performed in Barcelona at the final test.
"I had a good feeling all day and enjoyed working with my engineers, who I already know very well. The track is obviously evolving and improving, but we got a good feel for the tyres.
"The main focus tonight is to work on improving the balance on the supersofts."
