Dynamic Friction Company Disc Brake Rotor P/N:940-31131D
Bring smooth, steady braking back to your BMW with the DYNAMIC FRICTION brake rotor 604-31131D, a GEOSPEC-coated blank disc brake rotor for the front right position. It installs as a direct-fit replacement across a broad BMW lineup, including the 2017-2023 540I, 2017-2026 540I xDrive, 2016-2020 and 2023-2026 740I, 2020-2026 840I, 2019-2026 X5, 2021-2026 X6 and 2019-2026 X7 — see the Buyer's Guide tab for the full list of 28 applications.
Engineered to match the form, fit, and function of the OEM rotor, it arrives ready to install with no additional pre-degreasing prep needed. This rotor is sold individually and covers the front right position; for even, balanced braking it's best practice to replace both rotors on the same axle together as a matched pair.

Is this a front or rear brake rotor?

What is the GEOSPEC coating on this rotor?
GEOSPEC is DFC's rotor coating that provides corrosion protection beyond zinc or conventional painting, helping the rotor resist rust.
Does this rotor have cooling vanes?
Yes. It is a vented rotor built with an OE vane configuration for proper heat dissipation during braking.
Is the rotor sold individually, and should I replace both sides?
Yes, it is sold individually (one rotor). For even, balanced braking it is best practice to replace both rotors on the same axle together as a matched set.
