This product line emphasizes consistent rotor thickness and smooth surface finishes to ensure proper pad contact and braking efficiency. The 121.51049 rotor is part of this line, offering vented construction to help reduce heat buildup during braking on the Genesis G90.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis Centric disc brake rotor features a vented design that enhances airflow between the rotor surfaces, helping to dissipate heat generated during braking. The smooth surface type ensures even pad wear and quiet operation. With an overall height of 2.433 inches (61.8 mm) and a mounting bolt hole circle diameter of 4.5 inches (114.3 mm), it is engineered for precise fitment on the Genesis G90. The rotor’s floating disc mounting and three miscellaneous holes contribute to proper alignment and secure installation. Note that this rotor does not include an ABS tone ring or bearings, so those components must be sourced separately if required.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Genesis G90\u003c\/li\u003e\n\u003cli\u003eAddresses brake pulsation caused by uneven rotor thickness\u003c\/li\u003e\n\u003cli\u003eImproves braking performance by restoring proper rotor dimensions\u003c\/li\u003e\n\u003cli\u003eHelps reduce brake fade through vented rotor design\u003c\/li\u003e\n\u003cli\u003eEliminates noise issues related to rotor surface irregularities\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify rotor dimensions and bolt pattern match your Genesis G90 before installation\u003c\/li\u003e\n\u003cli\u003eEnsure the rotor surface is clean and free of contaminants prior to mounting\u003c\/li\u003e\n\u003cli\u003eTorque lug nuts to manufacturer specifications to avoid rotor warping\u003c\/li\u003e\n\u003cli\u003eCheck for proper clearance around the rotor and caliper assembly\u003c\/li\u003e\n\u003cli\u003eReplace brake pads simultaneously for optimal braking performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric manufactures the C-TEK Standard Disc Brake Rotors to meet strict quality standards, ensuring consistent thickness and material integrity.
