After a handful of track days, my coolant in the reservoir finally touched below minimum level. Filled it up with the blue OEM Honda coolant.

Curious of what kind of coolant brand folks that track their car use if not the OEM fluid?

OEM unless track rules specify otherwise. I've tried a bunch of different brands, it's all the same chemical formula. Tried a bunch of additives, saw no real difference.

Best changes to cooling performance have been changes to flow, capacity or air flow in and out of the radiator. Nothing in a bottle has been anything I would preach about.
