This rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade. The directional slotted and drilled surface improves water and debris evacuation, enhancing braking consistency in various driving conditions. The rotor’s plain disc finish combined with a Geospec silver grey hat finish provides corrosion resistance and a clean appearance. With a nominal thickness of 24mm and a discard thickness of 22.4mm, this rotor maintains structural integrity and performance throughout its service life. The 5-bolt hole pattern with a 120mm bolt circle diameter ensures precise fitment on compatible BMW models.\u003c\/p\u003e\u003ch2\u003eDFC Geoperformance Rotor - Drilled and Slotted Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Geoperformance Rotor - Drilled and Slotted line focuses on delivering rotors with enhanced surface designs such as drilling and slotting to improve braking efficiency and heat management.
