Best brake fluid for racing or even on the normal jobs. I work for a race team on Offroad dirtbikes and this is the best fluid we’ve ever used.

Best brake fluid for the race track. Done hot lap after hot lap without boiling this fluid. My vehicle was 3680lb with me in it

This stuff is expensive but if you are going to track your car, it’s the best.
