The rotors measure 327 mm in outside diameter and have a nominal thickness of 20 mm, ensuring compatibility with factory calipers and brake pads. Featuring a vented rotor design with straight vanes, these rotors promote consistent airflow to reduce heat buildup during aggressive driving or track use. The cross-drilled and slotted surface enhances pad bite and helps evacuate gases, dust, and water, improving braking response and reducing the risk of brake fade.\u003c\/p\u003e\u003cp\u003eThe coated hat finish protects the rotor hub from corrosion, maintaining structural integrity and appearance over time. The rotor’s floating mounting design with two additional holes ensures proper alignment and fitment on the vehicle’s hub assembly. With a 5-lug configuration and a 120 mm bolt circle diameter, these rotors are engineered to meet the exact specifications required for BMW M3 and M5 models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eImproves braking performance under high heat conditions\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during spirited driving or track use\u003c\/li\u003e\n\u003cli\u003eEnhances pad bite and braking response with slotted and drilled design\u003c\/li\u003e\n\u003cli\u003ePrevents corrosion on rotor hats for longer service life\u003c\/li\u003e\n\u003cli\u003eCompatible replacement for worn or warped factory rotors on BMW M3 and M5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is within discard limits: minimum 18.4 mm (0.724 inches)\u003c\/li\u003e\n\u003cli\u003eVerify compatibility with existing brake pads and calipers before installation\u003c\/li\u003e\n\u003cli\u003eClean rotor surface with brake cleaner to remove any protective coatings before use\u003c\/li\u003e\n\u003cli\u003eTorque lug nuts to manufacturer specifications to avoid rotor warping\u003c\/li\u003e\n\u003cli\u003eCheck for ABS tone ring compatibility; this rotor does not include an ABS tone ring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eStopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors are manufactured to meet or exceed OEM standards for fit, form, and function.
