Refresh your BMW's front brakes with the Dynamic Friction brake rotor 644-31108 (also written 64431108), a DFC GEOSPEC-coated, dimpled and slotted disc brake rotor. It installs as a direct-fit front rotor for many BMW models, including the 2017-2021 BMW 230i. See the Buyer's Guide tab for the full list.

Designed to meet the same form, fit, and function as OEM brake rotors, it arrives precision-built and ready to install with no additional pre-degreasing preparation needed.

  • GEOSPEC coating: provides superior corrosion protection over zinc or conventional painting.
  • Dimpled and slotted with a non-directional finish: promotes faster break-in and smoother stops.
  • CNC-machined and mill-balanced: 100% precision cut, designed for smoother stopping and zero vibration at any speed.
  • OE vane configuration: for proper, maximum heat dissipation, with premium G3000/G11H18 iron castings for strength, stability, and durability.

Replacing both front rotors together as a matched pair is recommended for even, balanced braking. This listing is for one rotor.
