Detailed Product Description

This Centric C-TEK Standard Disc Brake Rotor 121.67070 is a vented rotor featuring a straight vane design that promotes efficient airflow to reduce heat buildup during braking. The smooth surface finish ensures consistent pad contact and braking response. With a nominal thickness of 1.535 inches and a discard thickness of 1.472 inches, this rotor maintains structural integrity and safety standards throughout its service life. The overall height of 4.370 inches and an outside diameter of 15.366 inches make it suitable for vehicles requiring a 10-lug bolt pattern with a 6.693-inch bolt circle diameter. The floating disc mounting design allows for slight movement to accommodate thermal expansion and reduce stress on the rotor and hub assembly.

The rotor’s center hole diameter of 4.921 inches and stud/lug hole diameter of 0.669 inches are engineered to match specific vehicle hubs, ensuring proper fitment and alignment. Weighing 45.6 pounds, this rotor balances durability with manageable weight for effective braking performance. Note that this rotor does not include an ABS tone ring or bearings, so compatibility with the vehicle’s ABS system should be verified prior to installation.
