I’ll attempt to clarify again, DOT 4 reco by GM is too ambiguous. All brake fluids with DOT 4 are not necessarily up to the task of track duty with our ZL1s, some brands of DOT 4 have too low boiling point like standard Castrol DOT 4 vs SRF.
Your example of Motul 600 is true, it’s a good DOT 4, but I prefer 660 given the heat at tracks here in CA and temps my OEM and DS 1.11 pads generate.
My point wasn’t about Motul 600 it was about the basic DOT 4 reco by GM, I advise people to read details of boiling point before they buy.
