The track days I run ask you NOT to run anti freeze... just distilled water (and some water wetter). Because if you drip or spill on the track anti freeze doesn't just evaporate.
I've run EVANS -- but this creates different issues because you can't have ANY water or anti freeze in the system. Best if this is a "new" build and you're starting from scratch. And IIRC it's very expensive stuff. Then - if you have an issue... on the road or at the track... chances are nobody has any if you need some.
If it was me - figuring that you don't drive this car in the winter (as in it's not a DD)... and it's stored inside... I'd run distilled water and a bare minimum of anti freeze... and one bottle of Water Wetter. Water Wetter is a surfactant... it just makes the water molecules contact more surface area which helps take away more heat. The stuff is pretty effective. Plus you need lube for the pump etc.
Sutton may have some other ideas -- but my guess is anything he was involved with was stored in heated garages. LOL
