Welcome to

, Jack!
Good advice above.
Mr. Jubx2 has given you a starter set. You can search keywords and find more here.
I also do lo speed "parking lot) autoX and track hi-speed autoX.
Before I did my first DE (2-day driving school) I swapped out stock brake fluid to Motul 600, a DOT 4 fluid. Had Tony's Corvettes (<<<<<over there) do it, as I learned here that a complete change-out requires a Tech II equipment item.
I also added SpeedBleeders to make the bleeding process easier.
Brake heat is enemy # 1 for track time.
I have done about 6 DE days and keep a margin of safety, as I'm low on the learning curve and want to stay on the track!
I haven't lost my brakes, and I bleed off a 24" bleed tube's worth of fluid after every track day. I've just done a DRM Brake duct install, with phoenix spindle mounts, but haven't run with it yet ... waiting to get my duct hoses (backordered) from DRM!.

I've seen 278 oil temp and haven't triggered a tranny temp signal.
I'll be swapping out trans and diff fluids this fall.
HTH.
Enjoy!
