Keep your rear brakes running smooth with the DYNAMIC FRICTION brake rotor 604-31106 (also cataloged as 60431106), a GEOSPEC-coated, blank rear brake rotor. It installs as a direct-fit replacement across a wide range of BMW models, including the 2012-2018 BMW 640i, 2011-2016 BMW 535i and 2011-2016 BMW 550i — see the Buyer's Guide tab for the full list.
This DFC GEOSPEC rotor is CNC-machined to tight tolerances and cast from premium G3000/G11H18 iron for strength and stability. Designed to meet the same form, fit, and function as the OEM rotor, it arrives ready to install with no pre-degreasing preparation needed.
- OE vane configuration: retains the original vane layout for proper heat dissipation.
- Mill-balanced: 100% precision-cut and mill-balanced for smoother stops with reduced vibration.
- Premium iron castings: G3000/G11H18 iron for strength, stability, and durability.
- GEOSPEC coating & non-directional finish: corrosion protection beyond conventional zinc or painted finishes, plus a finish that promotes faster break-in.
The rotor provides the friction surface the pads clamp to convert motion into stopping force. Pulsation through the pedal, vibration under braking, or visible scoring can be signs a rotor is worn or warped and may need replacing — diagnose the cause before servicing. Sold individually; replace both rotors on the rear axle as a matched pair for even, balanced braking.
