Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted by Dynamite Friction is designed specifically for BMW X3 and X4 vehicles requiring reliable braking components. This rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade. The directional surface combines drilled holes and slots to improve water, dust, and gas evacuation from the braking surface, which enhances pad bite and overall stopping power.

With a nominal thickness of 28 mm and a discard thickness of 26.4 mm, this rotor maintains structural integrity and performance throughout its service life. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rust resistant coating further protects the rotor from environmental damage, extending its usable life.
