The rotor features a smooth surface type that promotes even pad wear and consistent braking performance. With a nominal thickness of 1.024 inches (26.000 mm) and a discard thickness of 0.961 inches (24.400 mm), it meets OEM specifications for durability and safety. The overall height of 1.870 inches (47.500 mm) and outside diameter of 11.024 inches (280.000 mm) ensure proper fitment and compatibility. The rotor uses a floating disc mounting system and straight vane style to optimize airflow and cooling efficiency during operation.\u003c\/p\u003e\u003cp\u003eThe rotor includes four stud\/lug holes with a diameter of 0.490 inches (12.450 mm) arranged on a 4.500 inch (114.300 mm) bolt circle diameter, matching the factory mounting pattern. The center hole diameter measures 2.717 inches (69.000 mm), ensuring precise alignment on the hub. This rotor does not include ABS tone rings or bearings, so it is intended for vehicles where these components are serviced separately.\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 specifications for standard replacement applications.
