Some good shots there. What lense was it? A few look a little bit soft. Don't look to be great conditions though.
I have a few friends who were there, the red Audi, the silver Es Cos and a Red Nissan Primera. They have all said it was the worst day they have been to. Fair few offs and muppets dumping oil over the track and proceeding to carry on half a lap. They'd only managed 2 laps by 11.30. Driving standard was supposedly poor with people not willing to let quicker cars past and overtaking under red flags.
