JGTC at Sepang Circuit?

I'll be attending the 3rd JGTC stage in Sepang Circuit, Kuala Lumpur, next month. But first, I've got some questions.

What will the atmosphere be like? I've gotten a ticket for the Main Grandstand. This is at the long straight area. Is the view there good? Can I reach the track with a 300mm lens?

Is the pit walkabout a free and easy type of event? Will we be able to get close to the cars?

Will there be any merchandise on sale? What kinds, and where?

During the night, will there be any sightseeing possible in Sepang? I get the idea that it's far from the city.

Has anyone here been to Sepang before?

I 'll be there too ... where is yours Location ?
Can't wait too see the Powerful monster like the F1 GTR , sard Supra and all the crazy GT300 model ....

The usual.. main grandstand, free seating. TheJGTC race is going concurrently with some classic car series.
