It's still a little strange to me that a car that is marketed as a track capable car comes with DOT 3 brake fluid. I'm guessing the ZL1 1LE will be no different which will be even more strange if that does in fact happen.
Given its wet boiling point, Castrol SRF looks like a great choice for a high-performance OEM fluid. Other than cost is their any downside that might explain why GM uses DOT 3 fluid? By either buying in huge quantities or by having DOW chemical produce a better fluid, I'm sure GM could keep the cost difference within reason.

I would guess it's simply a factor of how the plant is set up to fill everything else with DOT3.
