This product line focuses on solid rotors with smooth surfaces, suitable for standard braking applications where consistent performance and fitment accuracy are essential. The 121.99018 rotor exemplifies this approach with precise dimensions and a floating disc mounting style to accommodate typical vehicle brake systems.\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, optimized for vehicles requiring a 237.6 mm outside diameter rotor. The nominal thickness of 8.2 mm ensures adequate material for effective heat dissipation and wear resistance, while the discard thickness of 7.0 mm indicates the minimum safe thickness before replacement is necessary. The rotor’s overall height of 74.5 mm and center hole diameter of 66.2 mm provide compatibility with specific hub assemblies. The floating disc mounting design allows for slight movement to reduce stress and improve braking consistency. With four stud holes sized at 12 mm diameter and a mounting bolt hole circle diameter of 100 mm, this rotor fits vehicles with matching hub configurations. The absence of an ABS tone ring means this rotor is intended for vehicles without ABS sensor integration on the rotor itself.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors causing brake pulsation\u003c\/li\u003e\n\u003cli\u003eUpgrading from damaged or scored rotors to restore smooth braking\u003c\/li\u003e\n\u003cli\u003eAddressing rotor thickness below manufacturer discard limits\u003c\/li\u003e\n\u003cli\u003eResolving uneven brake pad wear due to rotor surface imperfections\u003c\/li\u003e\n\u003cli\u003eEnsuring proper fitment for vehicles requiring a 237.6 mm diameter solid rotor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify vehicle compatibility by matching rotor dimensions and bolt pattern\u003c\/li\u003e\n\u003cli\u003eInspect hub surface for cleanliness and damage before installation\u003c\/li\u003e\n\u003cli\u003eTorque mounting bolts to manufacturer specifications to avoid rotor warping\u003c\/li\u003e\n\u003cli\u003eReplace brake pads when installing new rotors to ensure optimal performance\u003c\/li\u003e\n\u003cli\u003eCheck for ABS sensor requirements as this rotor does not include a tone ring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric provides quality-tested disc brake rotors manufactured to meet or exceed OEM standards.
