The rotor’s nominal thickness is 0.783 inches (19.9 mm), with a discard thickness of 0.724 inches (18.4 mm), indicating when replacement is necessary to maintain safe braking. The overall height measures 2.406 inches (61.1 mm), and the outside diameter is 11.811 inches (300 mm), ensuring proper fitment on compatible BMW models. The rotor includes five lug holes with a 4.724 inch (120 mm) bolt circle diameter and a center hole diameter of 2.953 inches (75 mm) for accurate mounting. The smooth surface type supports even brake pad wear and consistent stopping power. This rotor does not include an ABS tone ring or bearings.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors causing brake pulsation\u003c\/li\u003e\n\u003cli\u003eAddressing reduced braking efficiency due to rotor thickness below discard limits\u003c\/li\u003e\n\u003cli\u003eResolving noise or vibration issues from uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eUpgrading to vented rotors for improved heat dissipation on BMW 540i and M5\u003c\/li\u003e\n\u003cli\u003eEnsuring proper rotor fitment and alignment with OEM specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Centric C-TEK Standard Disc Brake Rotor 121.34034, ensure the rotor surface is clean and free of contaminants before mounting. Verify the rotor thickness is above the discard limit of 0.724 inches (18.4 mm) to maintain safety standards. Use the correct torque specifications for the five lug bolts on the 4.724 inch (120 mm) bolt circle. Since this rotor does not include bearings or an ABS tone ring, reuse existing components if applicable. Properly seat the rotor on the hub using the 2.953 inch (75 mm) center hole for accurate alignment. It is recommended to inspect brake pads and replace if worn to optimize braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric manufactures the C-TEK Standard Disc Brake Rotors to meet or exceed OEM quality standards, ensuring reliable performance and durability.
