The nominal thickness is 24.0 mm (0.945 inches) with a discard thickness of 22.4 mm (0.882 inches), ensuring precise wear limits for safety and performance. The rotor includes a straight vane style for effective airflow and cooling. It features five stud\/lug holes with a diameter of 14.7 mm (0.579 inches) and a mounting bolt hole circle diameter of 120 mm (4.724 inches). The center hole diameter measures 79 mm (3.110 inches). 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 provide enhanced braking performance through improved heat dissipation and reduced brake fade. The combination of cross-drilled holes and precision slots helps evacuate gases and debris from the braking surface, maintaining consistent pad contact. The vented rotor design further aids in cooling, making this line suitable for both street and light track use. The coated hat finish protects against corrosion, extending the rotor's service life.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during aggressive driving or heavy braking\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to maintain consistent braking performance\u003c\/li\u003e\n\u003cli\u003eMinimizes brake dust and gas buildup on the rotor surface\u003c\/li\u003e\n\u003cli\u003ePrevents corrosion with coated hat finish for longer rotor life\u003c\/li\u003e\n\u003cli\u003eCompatible replacement for worn or warped rotors on specified BMW models\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 (22.4 mm) before installation\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for mounting bolts to avoid rotor warping\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with vehicle ABS system as this rotor does not include an ABS tone ring\u003c\/li\u003e\n\u003cli\u003eInspect brake pads for wear and replace if necessary when installing new rotors\u003c\/li\u003e\n\u003cli\u003eFollow manufacturer guidelines for bedding-in new rotors and pads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eStopTech rotors are manufactured to meet or exceed OEM specifications for fit, form, and function.
