Detailed Product Description

This Centric C-TEK Standard Disc Brake Rotor 121.22027 is a vented rotor featuring pillar-style vanes, which enhance airflow and cooling during braking. The rotor’s nominal thickness of 0.984 inches (25.000 mm) and discard thickness of 0.905 inches (23.000 mm) provide a clear service life indicator to maintain optimal braking performance. With an overall height of 1.937 inches (49.200 mm) and an outside diameter of 13.780 inches (350.000 mm), this rotor is designed to match the exact dimensions required for Land Rover Discovery, Range Rover, and Range Rover Sport models. The floating disc mounting and 5 lug holes with a diameter of 0.571 inches (14.500 mm) ensure secure installation and compatibility with OEM hardware. The smooth surface type promotes even brake pad wear and consistent stopping power.

The rotor does not include an ABS tone ring or bearings, so these components must be sourced separately if required. The center hole diameter measures 3.110 inches (79.000 mm), and the mounting bolt hole circle diameter is 120.000 mm (4.724 inches), matching OEM specifications for proper fitment.
