It's autoclub speedway. I am running S20s and Frosty you should be fine.
I had 6 months experience before I did my first track day. I am not sure where you are located but I would not recommend auto club speedway as your first track day. At least not on a 250. I did it and survived but I think doing CLASS at streets of willow would be a better option. More relaxed and geared towards street riders.
