Shame I'm going to be in Scotland when this happens. I've been round Brands Indy circuit twice and is good fun. Just have to be careful with the first corner your first couple of goes as you could end up in the gravel. If your lucky they will have all the pit garages open for everyone to use.
I'll add some links to youtube later as I've got some good video of me in my mini and my friend in his mx5 turbo going around brands.
