Gulf Competition RF800 is an extremely high performance glycol-based brake fluid designed for use in cars and motorbikes under racing, lapping, rallying, drift, and auto cross conditions. Not only does RF800 far exceed the requirements of the US Motor Vehicle Safety Standard 116 DOT 4, it has an exceptionally high boiling point, over 300 C, amongst the highest available in the market for glycol-based brake fluids. This feature distinguishes it from standard high performance brake fluids, as it is suitable for use even when the brake discs get so hot they start to glow orange-red. Under such high temperatures standard brake fluids could exceed their boiling point (typically 230-260C) and start to vaporize, thus seriously impairing braking performance. Available in 500ml size. For competition use only.
