This full coating extends the rotor’s service life and maintains braking efficiency, especially in environments prone to moisture and road salt exposure. This product line is engineered to meet or exceed OEM specifications, making it suitable for BMW 3 Series models such as the 323i, 325i, and 328i.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design with straight vanes to optimize airflow and heat dissipation during braking. The nominal thickness of 0.787 inches (20.000 mm) ensures structural integrity, while the discard thickness of 0.724 inches (18.400 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s outside diameter measures 11.803 inches (299.800 mm), and the overall height is 2.606 inches (66.200 mm). The hat and disc are fully coated to resist corrosion, and the smooth surface finish supports consistent pad contact and braking performance. The rotor includes five stud\/lug holes with a diameter of 0.579 inches (14.700 mm) and a mounting bolt hole circle diameter of 4.724 inches (120.000 mm). The center hole diameter is 2.953 inches (75.000 mm), and the rotor weighs approximately 13.75 lbs (6.25 kgs).\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW 323i, 325i, and 328i\u003c\/li\u003e\n\u003cli\u003eAddresses rotor corrosion and rust issues due to environmental exposure\u003c\/li\u003e\n\u003cli\u003eImproves braking consistency by restoring smooth rotor surface\u003c\/li\u003e\n\u003cli\u003eHelps reduce brake noise and vibration caused by uneven rotor wear\u003c\/li\u003e\n\u003cli\u003eSupports safe braking performance by maintaining proper rotor thickness\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is above the discard thickness of 0.724 inches (18.400 mm) before installation. Clean the hub surface to remove rust or debris for proper rotor seating. Use appropriate torque specifications for the 5 lug nuts to avoid rotor warping. Since this rotor does not include an ABS tone ring or bearings, verify compatibility with your vehicle’s existing components. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The full coating on the disc and hat provides enhanced corrosion resistance, contributing to longer service life.
