Side Note: I bought the car as a certified pre-owned, do you think it is possible the person before me changed it to DOT4? Because as mentioned I was kinda surprised I had zero brake fade under heavy braking throughout the whole entire day. For GM to qualify a car to be a certified pre-owned do they check or even flush the brake fluid?

I am going to offer that you should change the fluid to DOT4, very soon. After each track session, you should bleed the brakes a bit. In your case the bleeding is even more needed (stock fluid probably has some bubbles and such). If you are going to go through the work / costs of bleeding, I would suggest going ahead and changing the fluid. I run Motul RBF 600. I ran it in my SS daily and track use. I am now running it in my ZL1 (1st track day Saturday).
