This coating enhances rust resistance, extending rotor life and maintaining braking efficiency under various environmental conditions. The vented rotor design improves heat dissipation during braking, helping to reduce brake fade and maintain consistent stopping power. With a nominal thickness of 39.10 mm and a discard thickness of 37.40 mm, this rotor meets precise specifications for rear brake systems requiring a 10-lug mounting pattern and a 163 mm bolt circle diameter.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rear disc brake rotors\u003c\/li\u003e\n\u003cli\u003eAddressing brake noise caused by rust or uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eImproving heat dissipation to reduce brake fade on heavy-duty or frequent stop driving\u003c\/li\u003e\n\u003cli\u003eRestoring braking performance on vehicles with corroded rotors\u003c\/li\u003e\n\u003cli\u003eCompatible with vehicles requiring a 10-lug, 163 mm bolt circle diameter rear rotor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is within the nominal range before installation. Clean the mounting surface and hub to prevent uneven rotor seating. Use proper torque specifications for the 10 lug nuts to avoid rotor warping.
