The rotor has an overall height of 2.028 inches (51.500 mm) and an outside diameter of 11.811 inches (300.000 mm), designed to match the OEM specifications for the listed BMW models. The rotor includes five stud\/lug holes with a diameter of 0.575 inches (14.600 mm) and a mounting bolt hole circle diameter of 4.724 inches (120.000 mm). The center hole diameter measures 3.110 inches (79.000 mm). The rotor is vented with straight vanes to optimize airflow and cooling during braking. This rotor does not include ABS tone rings or bearings.\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 designed to enhance braking performance by combining cross-drilled holes and precision slots. This design improves heat dissipation and helps remove brake dust and gases from the rotor surface, which can improve pad bite and reduce brake fade. The vented rotor construction further aids in cooling, making these rotors suitable for spirited driving and daily use on compatible BMW vehicles.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during aggressive or extended braking\u003c\/li\u003e\n\u003cli\u003eImproves brake pad cleaning for consistent braking performance\u003c\/li\u003e\n\u003cli\u003eHelps prevent rotor warping caused by excessive heat buildup\u003c\/li\u003e\n\u003cli\u003eProvides corrosion resistance with coated hat finish\u003c\/li\u003e\n\u003cli\u003eMaintains OEM fitment and performance for BMW 323i, 325Ci, 325i, 325xi, 328Ci, 328i, Z3, and Z4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness (0.803 inches) before installation\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for mounting bolts to avoid rotor distortion\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with existing brake pads and calipers on your BMW model\u003c\/li\u003e\n\u003cli\u003eInspect hub surface for cleanliness and flatness prior to installation\u003c\/li\u003e\n\u003cli\u003ePerform a proper bed-in procedure after installation for optimal braking performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eStopTech disc brake rotors are manufactured to meet or exceed OEM standards for fit, form, and function.
