Yeah I'd be happy to keep the coolant levels on low when it's cold. As long as it's first thing in the morning and the engine hasn't been running overnight, the overflow is going to get any lower and suck air into the lines.

When you go to the track you will notice how much it all expands. I found if mine is much above the low line when cool, it will overfill the resevoire and give te engine bay a nice wash with coolant.
