You will destroy your tires....go buy used one's and have them mounted before you go
YEP.
I used to teach an entry level autocross course and yes, newbies shredded their tires. Every once in a while a kid got Dad's hot car, and then I helped shred the tires.
It is a lot of fun if you know what you are doing. I don't own a car I dislike enough right now.
