The rotor features a vented design with straight vanes that promote efficient heat dissipation, reducing the risk of brake fade during extended use. Its smooth surface type supports consistent pad contact and braking response. The rotor’s nominal thickness of 0.709 inches (18.0 mm) and discard thickness of 0.630 inches (16.0 mm) provide clear service limits for maintenance. With an overall diameter of 11.878 inches (301.7 mm) and a height of 2.236 inches (56.8 mm), this rotor fits the specified mounting bolt pattern of 5 lug holes spaced on a 4.5 inch (114.3 mm) bolt circle diameter. The floating disc mounting style allows for slight movement to accommodate thermal expansion and improve rotor longevity.\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 fit, form, and function.
