Red Bull Racing's Sebastian Vettel
has conceded the team will need to make a few changes overnight as they look to find the sweet spot with the RB9 and address some tyre wear issues ahead of Sunday's Malaysian Grand Prix.
Vettel was strong in practice on Friday and was third fastest this morning in the opening session. He then went second quickest this afternoon, ending the day only 0.019 seconds off Australian GP winner Kimi Raikkonen, who was fastest for Lotus.
Despite being at the top end of the times though, he was again concerned about the tyres.
“I think it was unusual today as in the second session one part of the track was pretty wet and the other was dry – but it all dried out quite fast, as it was so hot. This afternoon we couldn't do so much due to the weather, but this morning it looked okay, although the tyres don't last very long! We need to try a couple of things now overnight to improve and take a step forwards,” he confirmed.
Team-mate Mark Webber
meanwhile also went well in practice and having been quickest in FP1, he was fifth in FP2.
Speaking after the second session, he also emphasised that the tyres will again be key.
“It was a pretty smooth run for us today, but we need to improve and keep finding pace,” he remarked. “The slicks were not too bad in those conditions and the crossover point looks quite interesting. The tyres are still the most important thing at the moment – it's all about those!
“It's pretty warm in the car, but if I'm warm, then so is everyone else and in general it's not as bad as previous years.”
