Coolant ratio

I'm getting my car(E90 328i) ready for Barber this weekend. Should I run a higher water/coolant ratio? can I do only distilled water?

l know the coolant lubricates the water pump, so I'm assuming there should be some coolant in the system.

The N52 should be able to handle the heat but if I can make it easier on the engine the why not.

My car is a base 328i, sport pkg, manual, only mod is the PE!

BTW, anybody going to Barber on Memorial day weekend?

Engine is unlikely to overheat, standard coolant is fine. Don't run distilled water.
