Were you braking hard enough to activate ABS at the autox course? If yes go for the pad upgrade to XP10's, if not it might be a waste early on but you'll be able to grow into the pads, maybe XP8's will be a better place to start if you're not comfortable braking at the limit yet. Hell my first ever track day was fine on a totally stock brake system, I faded the pads and boiled the fluid on my second day.

I switched to XP10 on my third track day and I think they're a great starter pad. Get the same pad front and rear, measure the rotors, if they're above minimum thickness you'll be fine, if they're close to the limit order a new set. So that means measure them in time to get a replacement for the track day. But the rotors are stout as fuck, don't be surprised if there's lots of life in them, especially on a newer car. Don't worry about swapping rotors specifically for pads and all that other stuff slap 'em in and go run 'em, they'll stop just fine to get you to the track, they'll be loud but on the way home they'll be great until the transfer layer wears off. I swapped back to street pads after the event because I couldn't keep the XP10's bedded in, others can but I was fine with the extra work and did not track enough to justify leaving them in.

Do a brake fluid flush as well, Motul RBF600 or 660 to be safe.
