Red Bull's Mark Webber has set the fastest time in the final practice session ahead of tomorrow's Brazilian Grand Prix.

Lotus Renault driver Romain Grosjean came in second, while his teammate Heikki Kovalainen clocked the third-fastest time in a rain-soaked session.

Red Bull's Sebastian Vettel did only one timed lap, while the Ferrari drivers, McLaren's Jenson Button and Mercedes's Nico Rosberg did none. Their decisions came as teams attempted to save their tyres ahead of qualifying later today and the race tomorrow, which both look to be impacted by wet conditions.

Mercedes driver Lewis Hamilton, who had earlier bemoaned the idea of a wet track, set an impressive time during the weather's worst offering, recording a lap which was only two seconds slower than Webber, who had taken to the track in more favourable conditions.
