Here is the Spa-Francorchamps go-kart track.
Of course it is still in work. So especially pit lane isn't finished right now. Besides some objects (cars, visitors and so on) are missing.
- TV cameras (done)
- pit lane
- AI line
I've found this kart, made by rex1825: http://www.racedepartment.com/downloads/gokart.3589/
