600 Re-branded as Radi-CAL™ R2 - Silver bottle with Blue cap.

AP Racing’s R2 fluid has a dry boiling point of 312°C and has been specially developed to provide outstanding performance for racing applications where braking systems operate at high temperatures.

R2 fluid also conforms to and exceeds DOT4 specifications, but should not be used with components made from magnesium.

Note: R2 can be mixed with DOT4 racing brake fluids, but for maximum product performance the brake system should be thoroughly purged with R2 fluid.
