Looks like fun. Steve (ahdoman) and I are thinking about going in 914 (hopfully not too hot out).
World Class Motoring has a full motion race simulator that we'll get to play with for a bit. Then there is a drive over to Kundensport in Camarillo where they are restoring a Gulf 917. Then another drive to Paramount Ranch and then a dinner and drinks at Villa de la Vina in Agoura Hills.
The info can be found here:
