BMW M2, M3 and M4 track-day brake fluid

RBF 660 is the fluid we include in our BMW F8X track brake packages for compatible cars with the factory blue Brembo calipers. If you are preparing a BMW M2 F87 or M2 Competition, M3 F80 or M4 F82/F83 for circuit use, browse the BMW M2 brake collection, BMW M3 brake collection and BMW M4 brake collection.

For a complete package, see our BMW F8X front track brake bundle or BMW F8X front and rear track brake bundle. Both combine RBF 660 with track-focused pads, braided lines and brake cooling.

RBF 600, RBF 660 or RBF 700?

RBF 600 offers a 312°C dry boiling point. RBF 660 raises this to 325°C and is a strong all-round choice for harder track use. RBF 700 reaches 336°C dry for the highest dry-boiling performance in the trio. Our RBF660 vs RBF700 guide explains the trade-off in more detail.

Fitment and use

Always confirm that your vehicle and braking system require a compatible DOT 4 fluid. Do not use with silicone-based brake fluids or LHM. Brake fluid absorbs moisture, so keep the bottle sealed until required and follow the correct service and bleeding procedure for the vehicle.
