Dynamic Friction Company Disc Brake Rotor P/N:900-31157
Help address brake pulsation and keep the front axle stopping cleanly with the Dynamic Friction brake rotor 604-31157 (also written 60431157). This GEOSPEC coated, blank disc brake rotor drops in as a direct-fit front replacement for many vehicles, among them the 2021-2024 BMW 228i Gran Coupe, 2020-2024 BMW 228i xDrive Gran Coupe and 2018-2023 BMW X2 — see the "Vehicles it fits" section for the full list and engine-level fitment.
Designed to meet the same form, fit, and function as OEM brake rotors, it provides a fresh friction surface for your pads to clamp against on the listed front applications. If a warped, scored, or worn front rotor is behind your steering-wheel shudder or brake pulsation, this replaces it.
Will the Dynamic Friction brake rotor 604-31157 fit my vehicle?
It is a direct-fit front rotor for many vehicles, including the 2021-2024 BMW 228i Gran Coupe, 2020-2024 BMW 228i xDrive Gran Coupe and 2018-2023 BMW X2. Check the "Vehicles it fits" section for the full list.
Is this a front or rear rotor?
It is cataloged as a front brake rotor for the listed applications.
What does the GEOSPEC coating do?
It is a coating applied to the rotor that provides superior corrosion protection compared with zinc or conventional painting.
Is this a drilled or slotted rotor?
No. It is a blank rotor with a non-directional finish, which promotes faster break-in and smoother stops.
Should I replace both front rotors at the same time?
For even, balanced braking it is best practice to replace the rotors on both sides of the axle together as a matched pair. This listing is for one rotor.
