Motul RBF 660 Factory Line is a high-temperature DOT 4 racing brake fluid for demanding performance, track-day and motorsport use. With a 325°C dry boiling point and 205°C wet boiling point, it provides additional fresh-fluid temperature headroom over RBF 600.
Key features

- DOT 4 high-performance racing brake fluid
- Suitable for compatible hydraulic brake and clutch systems requiring non-silicone synthetic fluid
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.
FAQ
Is Motul RBF 660 suitable for a BMW M2 track day?
RBF 660 is included in our F8X track brake bundles for compatible BMW M2, M3 and M4 applications using the factory blue Brembo setup. The required fluid specification and condition of the complete braking system should still be checked before circuit use.
What is the boiling point of RBF 660?
325°C dry and 205°C wet.

Motul FAQs
Helpful answers before you order. Need more detail? Our team can help.
How do I choose the correct fluid?
Match the specification and approvals stated in your vehicle documentation to the product listing. Viscosity or product name alone may not confirm suitability. Contact us with your vehicle and application if you need help.
How much should I order?
Check the required service quantity in your vehicle documentation and the bottle size selected above. Order the quantity needed for the job; a single bottle is not necessarily a complete service fill.
When will my order arrive?
Select your required option and check the live availability message above. Dispatch is when your order leaves us; delivery takes additional time and depends on the service and destination. If no verified lead time is shown, or you need the item for a fitting appointment or event, contact Nineteen72 Performance before ordering.
What is included in the price?
Check the product description, selected option and stated quantity before ordering. Images may show optional equipment or an example installation. If you need a matching pair, a complete kit or additional hardware, ask us to confirm exactly what is included.
How do I get help before ordering?
