I pulled a lot of data prior to making the switch to 70/60 pads and then again after. When you switch to dedicated track pads using a less aggressive compound on the rear will prevent the rear tires from locking up under hard braking. This allows you to use more brake pressure before you activate ABS, and will drastically decrease your stopping distance. I have proven this on my 13zl1, 18zle 18CTSV, and come next weekend I will be running this setup at Road America on my 22ZLE...
Keep in mind that GM also had to consider real-world conditions and how the car stops on the street, in the wet, and in colder conditions. That plays a larger part in how they tune the brake system. If you were to use 70/60 on the street the front would lock up early engaging ABS and causing longer stopping distances...
