Going to the CA Superbike School 2 day course next month at Willow Springs. What should I know ahead of time?

I've been wanting to do this for a few years now and finally had the screw it moment and signed up. I haven't been able to do a track day and I think this would be the introduction I need to get into it. What should I do to prepare for the course? I'm renting a suit but is there anything else I should get for myself ahead of time? Those bottom layers look like a really good idea, but, would it be worth getting my own boots also? Or anything else. via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/96ya9m/going_to_the_ca_superbike_school_2_day_course/?utm_source=ifttt
