Fluids for trackdays

Hi, figured I would ask some questions since it's getting cold out and I'm new to track bikes.


1) Should I put anti-freeze/water mix in while it sits in my non-heated garage? Or should I drain the coolant completely? I plan to run water/water wetter mix next season. But I think having water/water wetter right now, will not be good in cold temps right?


2) What's the best motor oil to use for race/track bikes?

3) Best brake fluid, clutch fluid etc....?

Thanks
