Which Should You Choose?
Motul RBF 600 is the go-to option for most drivers, delivering outstanding performance for track days and aggressive driving with a slightly lower price point. It’s more than capable for GR86/BRZ owners running steel rotors and occasional track sessions.
Motul RBF 660 is designed for extreme conditions — endurance racing, repeated heavy braking, or carbon/ceramic setups. If you regularly push your car at the limit on track or in competition, the higher dry boiling point provides extra safety margin against brake fade.
Summary
- Choose RBF 600 for: track days, street performance, and value
- Choose RBF 660 for: endurance racing, carbon/ceramic brakes, and maximum fade resistance
