These rotors are designed to meet or exceed OEM specifications, providing dependable performance for vehicles like the BMW Z3. The line focuses on solid rotors with smooth surfaces, suitable for drivers seeking consistent braking without the need for vented or drilled designs.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis Centric disc brake rotor features a solid construction with a smooth surface type, ensuring even pad contact and reduced noise during braking. The rotor’s nominal thickness of 0.394 inches (10.000 mm) and discard thickness of 0.331 inches (8.400 mm) define its service life and replacement threshold. With an outside diameter of 10.709 inches (272.000 mm) and an overall height of 3.276 inches (83.200 mm), it fits precisely on BMW Z3 models requiring this specification. 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 120.000 mm (4.724 inches), ensuring secure installation. Note that 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 on BMW Z3\u003c\/li\u003e\n\u003cli\u003eAddresses brake pulsation and vibration issues\u003c\/li\u003e\n\u003cli\u003eRestores proper rotor thickness for safe braking\u003c\/li\u003e\n\u003cli\u003eEliminates noise caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eImproves braking consistency and pedal feel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface is clean and free of rust before installation. Verify the rotor thickness with a micrometer to confirm it meets the nominal thickness and is above discard thickness limits. Use proper torque specifications for mounting bolts to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, reuse existing components or replace separately if needed. It is recommended to replace brake pads simultaneously for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric C-TEK Standard Disc Brake Rotors are manufactured to meet OEM standards for fit, form, and function.
