So, after exploring there for a while, I headed up to the stands to watch the racing - there was nothing going on in the paddock and getting into the pits (although not possible with a paddock pass, many people were doing it anyway) was a bit tricky today.
There were 4 events - Formula BMW Asia, Formula Renault V6 Asia, Porsche Carrera Cup Asia and ATCC (Asian Touring Car Championship). Out of these events, I'd have to rate the tin tops as the more exciting to watch due to the larger grid (the formula cars only had about 10 cars per race) and the closer racing - the cars were always bumper to bumper and there was rarely a lone car. Unfortunately, I didn't get that many photos of the events due to the fact that I was on full zoom, and my camera focuses poorly (Canon A85 for those wondering), anyway - here are the best images from the bunch.
Formula BMW Asia
This is the first event of the day, and to be honest, it was pretty dull. The grid size was very small and after a few laps the cars were pretty spread out. It's a relatively new series though, so once more participants join and people learn the cars, it should become pretty interesting.
The most exciting part of the race - this car started smoking and the marshalls attacked it with fire extinguishers.
