The rotor’s overall height measures 3.039 inches (77.200 mm), with a center hole diameter of 3.110 inches (79.000 mm) to fit the specified BMW models accurately. The rotor is vented with straight vanes to optimize airflow and cooling, which helps maintain consistent braking performance under demanding conditions. The floating disc mounting design allows for slight movement between the rotor and hub, reducing stress and improving rotor longevity. The rotor weighs approximately 23 lbs (10.45 kgs), balancing durability and performance.\u003c\/p\u003e\u003ch2\u003eStopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors Product Line\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors line is designed to enhance braking efficiency through advanced rotor surface technology.
