This pair of rear left and right Dynamic Friction 385x24mm cross-drilled brake rotors fits F85 X5M (2015-2018) and F86 X6M (2015-2019). The rotors feature DFC's proprietary GEOSPEC anti-corrosion coating, and are a direct replacement for the factory rear brake rotors. These DFC brake discs are less costly than original equipment, and will offer comparable performance.
These DFC cross-drilled rotors are a single-piece cast iron design with anti-corrosion coating, which is a great way to reduce your brake rotor replacement cost. The factory BMW rotor is a 2-piece iron disc with an aluminum hub. BMW advertised the lighter weight as a way of lowering emissions and improving fuel economy. There is likely no performance difference between them but the Zimmermann will be slightly heavier compared to stock. We also offer the Original BMW rotors if you wish to keep the lighter two-piece design.
