Restore smooth, confident stops at your BMW's rear axle with the Beck/Arnley Disc Brake Rotor 083-3678, a direct-fit rear brake rotor for a wide range of BMW cars including the 2016-2018 320i xDrive, 2012-2015 335i, 2014-2016 428i, 2017-2020 430i and 440i, and the 2014-2015 ActiveHybrid 3 — see the Buyer's Guide tab for the full list of 27 applications.

  • OE form, fit and function: engineered as a direct replacement for Original Equipment applications across foreign nameplates, with attention to form, fit, and function.
  • Directional finish: optimizes break-in and helps the pads seat properly.
  • High carbon content: maximizes thermal conductivity.
  • High-temp coating on exposed surfaces: improves appearance.

This rotor is application-specific for the listed vehicles and mounts at the rear. Rotors wear together, so replacing both left and right sides as a matched pair is recommended for even, balanced braking — this listing is for one rotor; order the quantity your vehicle needs.
