Give your rear brakes a fresh, true braking surface with the Dynamic Friction brake rotor 604-31114, a DFC GEOSPEC coated blank rotor. It fits many vehicles, among them the 2021 BMW 230I, 2021 BMW 230I Xdrive and 2021 BMW M240I. See the Buyer's Guide tab for the full list and engine details.
This rear disc brake rotor is CNC-machined to the tightest tolerances. DFC designed it to meet the same form, fit and function as OEM brake rotors.
- OE vane configuration: Follows the original equipment vane configuration and is designed for proper heat dissipation.
- Precision cut and mill-balanced: Every rotor is precision cut and mill-balanced for smoother stopping. A non-directional finish promotes faster break-in and smoother stops.
- Premium iron castings: Engineered with premium G3000/G11H18 iron castings for strength, stability and durability.
- GEOSPEC coating: DFC says the coating provides superior corrosion protection compared with zinc or conventional painting.
Each rotor is quality tested. It arrives ready to install, with no additional pre-degreasing preparation needed, which saves time during installation. For even, balanced braking, replace both rear rotors together as a matched pair.
Signs a rotor may need replacing include a pulsating brake pedal, vibration when braking, deep scoring or grooves, and wear below the minimum thickness. Diagnose the cause before replacing parts.
