Technical Description and Specifications

This Centric disc brake rotor features a vented design with straight vanes that promote effective heat dissipation during braking. The rotor’s nominal thickness is 0.941 inches (23.9 mm), with a discard thickness of 0.882 inches (22.4 mm), indicating when replacement is necessary to maintain safe braking performance. The rotor measures 13.583 inches (345 mm) in outside diameter and has an overall height of 3.094 inches (78.6 mm). It includes five stud/lug holes with a diameter of 0.65 inches (16.5 mm) arranged on a 4.724 inch (120 mm) bolt circle diameter. The center hole diameter is 2.953 inches (75 mm). This rotor does not include an ABS tone ring or bearings, so those components must be sourced separately if required.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on BMW X5 and X6
• Addresses brake pulsation caused by uneven rotor surfaces
• Restores proper rotor thickness for safe braking performance
• Improves heat dissipation to reduce brake fade during extended use
• Suitable for standard driving conditions requiring OEM-level rotor quality

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean rotor surface and hub mounting area to prevent runout
• Torque lug nuts to manufacturer specifications for BMW X5 and X6
• Check compatibility with existing brake pads and hardware
• ABS tone ring and bearings are not included and must be installed separately if applicable
