I see where some people have posted on the Camaro Fest NCM thread to make sure to swap in DOT 4 brake fluid before the track event. It looks like the stock fluid has a dry boiling point of 487 degrees (F) which seems to me might be enough to cover an amateur on a track day.

I understand when the fluid boils it's bad news. I also understand the "better safe than sorry" argument to make a preventative change.
I'm wondering specifically has anyone tried the '17 ZL1 on a track day with the stock brake fluid? If so, did it work out okay?
