I was out there yesterday to watch a mate (the blue ae86) - first time I've been to the sprints and I couldn't believe how hectic it is. Cars everywhere in the pits and almost always cars out on the track. Real variation of cars tho, so it was great to watch.
I can't go near QR without my camera gear, so I got a heap of photos while watching. I don't know which of the cars were SAU people, but here's some of the skylines:

I tried to get shots of every car, but if you were out there and can't find any of yours then PM me and I'll take a look.
