RAVENOL R325+ Racing Brake Fluid is a specially developed high performance brake fluid that has a very high thermal resistance at the highest DOT 4 level. The formula is based on top class technology with a glycol ether / ester system. The use of a proven additive combination in conjunction with a basis system that is specifically adjusted for the high boiling range, guarantees safety even under the most extreme loads. Enhanced lubricity helps extend the life of the metal moving parts of the brake system and increases system efficiency.

RAVENOL R325+ Racing Brake Fluid is an ideal brake fluid for motor sports and is used by many leading race & rally teams, including 24H endurance racing and international rallying. Tested to a dry boiling point of 328°C and offers outstanding resistance to vapour lock and pedal fade, even under the extreme conditions. .


RAVENOL R325+ Racing Brake Fluid is a high performance brake fluid specially developed specifically for use in all forms of competitive motor sport. To achieve optimum results, the braking system should be freshly filled with RAVENOL R325+ Racing Brake Fluid before each race. In particular when the brakes are inordinately hot or racing under tropical conditions.

Not suitable for vehicles that require a mineral brake fluid (LHM). Not recommended if the components used are made of magnesium or are alloys with a high magnesium content. Do not mix with other brake fluids.

If the customer requests delivery to be left in a 'safe place' we cannot be held responsible for loss.
