If you're going to track race your car then, using a brake fluid such as Amsoil or speciality brands will probably out perform any over the counter fluids.
I have only used store brand brake fluid from AAP & W*M for the last 25 years and I can't complain. As the matter of fact, my brakes in all of my vehicles in the last 25 years feel awesome, even to those who may drive my vehicle for the day.
To me, most off the shelf brake fluid is brake fluid. Amsoil's specific fluid may be for super hard core braking that doesn't include my type of driving style even when I can become aggressive.
