Yes you can run you car in Outlaw class, I think it will also can be run on sedan class. 1/8 is no problem at all. Regarding electrics, we had been inviting them on every state race we have, even for free, and they don't show up, it is a dead class.
30% fuel there isn't a problem, that is what must of us use. I run Maxys 30%.

Personal trasnponder are required to participate. regarding tire, we use to run with 42front and 45 rear for long mains, but right now the track is been repaved so we will know on april how is consuming tires.
About hotels, it will depend on your budget. Good hotels can be found on metro are at prices starting from a $100.00 per night. They are at about 30 to 45 minutes from the track. You must plan in advance in order to find a good one at a good price.
