If you are running stock brakes in a 64 - 89 911 (not turbo), ATE super blue is not enough for real racing. I base this on testing at a track with a ~ 1 mile front straight, a shorter track may allow for less heat. I would get fade after 3 laps with super blue (I put it in after a repair at the track). At the time I had stock brakes in my 77 with race pads. I had been running DOT 5.1 before I put in the super blue.

With an improved setup (better calipers, rotors) you can run a crappier fluid such as super blue because these can shed the heat better.

This car now has a Turbo brake setup with Pagid RS29s and could probably run super blue but I stick with the Brembo LCF600...
