The rotor has a nominal thickness of 30 mm and a discard thickness of 28.4 mm, ensuring it meets safety standards for replacement intervals. Its overall diameter measures 324 mm (12.756 inches), with a smooth surface type that promotes even brake pad wear. The rotor includes a coated hat finish to protect against rust and corrosion, extending the rotor's service life. With 5 bolt holes arranged on a 120 mm bolt circle diameter, it fits securely on the hub, which has a center hole diameter of 79 mm. The floating disc mounting design allows for slight movement to maintain proper alignment and reduce stress on the braking system.\u003c\/p\u003e\u003ch2\u003eAbout Centric Premium Disc Brake Rotors\u003c\/h2\u003e\u003cp\u003eThe Centric Premium Disc Brake Rotors line is designed to provide a balance of performance and durability for daily driving and moderate performance needs.
