Webber tops final Spa practice
Third practice was stunningly representative for Spa this year, with a drying track during the session before a torrential downpour in the last 15 minutes. Mark Webber went fastest on slicks just before the downpour, faster than Lewis Hamilton and his teammate Sebastian Vettel.
