Ive run Evans Coolant in all my previous track cars.

I'll wait until my warranty is up then add it.
There is no water in it and its a one time fill. Jay Leno uses it in all his cars.
Water is still a better conductor of heat removal but if it reaches 212 degrees then all kinds of problems arise.
One f the best things about EVANS is it doesn't expand or boil like water does.
YMMV
