Technical Specifications and Features

This disc brake rotor is a solid type with a directional surface featuring both drilled holes and slots. The rotor measures 324 mm in outside diameter and 80.1 mm in height, with a nominal thickness of 12 mm and a discard thickness of 10.4 mm, ensuring precise wear limits. The rotor includes five bolt holes and stud/lug holes, each 16.6 mm in diameter, arranged on a 120 mm bolt circle diameter. The zinc silver hat finish provides rust resistance, extending the rotor's service life.

Applications and Problem Solving

• Replaces worn or warped rotors on BMW X5 models
• Improves heat dissipation to reduce brake fade during heavy use
• Enhances braking performance with directional drilled and slotted design
• Prevents rust and corrosion with zinc silver coating
• Maintains consistent braking feel and pad contact

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 10.4 mm before installation. The directional surface requires correct orientation during mounting to maintain optimal braking performance. Verify bolt hole alignment with the 120 mm bolt circle diameter and 16.6 mm bolt hole diameter for proper fitment on BMW X5 hubs.
