Good Fluid. Its dry boiling point performance is not as high as other high performance brake fluids or even Ford Heavy Duty DOT 4 which is also a good option for the price. But this liquid has a higher boiling point when wet. That way, even if the fluid ages or you boil over after a hard day at the track, you still have a good fluid that exceeds DOT 4 specs. I have yet to go through my fluid change interval and will be going to the track with fresh fluid. If I run into any problems I'll let you know, but don't expect me to run into any problems. at least with brakes.
