A "little" being subjective, as stated, it's critical that you don't boil the fluid. With that said, for
ME, I pushed it to the limits. It's also important to understand that I'm running Willwood EXP 600 DOT-4 fluid, so my boil temp is even higher than the O.E. stuff.
If you're going to the track, a premium DOT-4 fluid is something you should strongly consider.

I like the Wilwood because it's an excellent balance of price over performance. There are arguably better fluids out there, but at substantially higher cost than even the Wilwood (2X or more) which in my view is pretty expensive, especially if you're refreshing at the track each session like many do.
