This product line is tailored for drivers seeking a balance between performance and durability in their braking components.

Technical Specifications and Features

This disc brake rotor is a solid type with a directional surface pattern, featuring both drilled holes and slots. The rotor has a nominal thickness of 9 mm and a discard thickness of 8 mm, ensuring safe replacement intervals. The rotor's outside diameter measures 292 mm, with an overall height of 64 mm. It includes 5 bolt holes arranged on a 114.3 mm bolt circle diameter, compatible with the Infiniti Q45's wheel hub. The rotor hat is finished in zinc silver, providing rust resistance, while the disc surface has a plain finish optimized for braking performance.

Applications and Problem Solving

  • Replacement rotor for worn or warped Infiniti Q45 brake rotors
  • Improves heat dissipation to reduce brake fade during heavy braking
  • Helps maintain consistent braking performance under demanding conditions
  • Addresses rotor corrosion issues with rust resistant coating
  • Suitable for drivers requiring directional rotors with drilled and slotted surfaces

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 8 mm before installation. The directional surface requires correct orientation during mounting to maintain optimal braking performance. Verify the 5-lug bolt pattern with a 114.3 mm bolt circle diameter matches the vehicle hub. Clean the rotor surface of any protective coatings before installation to prevent brake pad contamination.
