The cross-drilled and slotted surface pattern helps to reduce brake fade by improving heat dissipation and allowing gases and debris to escape from the rotor surface. The vented design with straight vanes further enhances cooling during heavy braking conditions.\u003c\/p\u003e\u003cp\u003eThese rotors feature a coated hat finish that provides corrosion resistance, extending the rotor's service life. The rotor's overall diameter measures 299.8 mm (11.803 inches) with a nominal thickness of 20.0 mm (0.787 inches), ensuring compatibility with the specified BMW models. The mounting configuration includes five lug holes on a 120 mm bolt circle diameter, with a center hole diameter of 75 mm (2.953 inches), designed for a floating\/dih disc mounting style.\u003c\/p\u003e\u003ch2\u003eAbout the StopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors Line\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors line is developed to provide enhanced braking performance through improved heat management and surface friction characteristics. The combination of cross-drilled holes and precision slots helps maintain consistent brake pad contact and reduces the risk of glazing.
