AP Racings R3has a dry boiling point of 325C (608F) and has been developed for racing use only.

R3has advanced moisture resistance properties, low levels of viscosity (for ease of bleeding), low levels of compressibility and meets DOT4 specifications.

R3is suitable for all top levels of motorsport where abnormal temperatures are experienced and with the introduction of an inhibitor, can now be used with magnesium components

R3can be mixed with other DOT4 racing brake fluids, but for maximum product performance the brake system should be thoroughly purged withR3fluid.
