The vented design features straight vanes that enhance airflow, helping to reduce heat buildup during braking. The rotor’s smooth surface ensures even pad wear and consistent braking response. With an outside diameter of 12.402 inches and a nominal thickness of 0.787 inches, this rotor meets OEM specifications for fit and function. The mounting bolt hole circle diameter is 5.5 inches (139.7 mm), accommodating five lug holes, each 0.492 inches in diameter, ensuring secure installation. The center hole diameter of 3.791 inches allows proper centering on the hub. This rotor does not include an ABS tone ring or bearings, so it is intended for vehicles without those integrated components.\u003c\/p\u003e\u003ch2\u003eAbout the C-TEK Standard Disc Brake Rotors Line\u003c\/h2\u003e\u003cp\u003eThe C-TEK Standard Disc Brake Rotors line by Centric offers rotors designed to meet or exceed OEM standards for fit, form, and function.
