Detailed Product Description

This disc brake rotor is specifically designed for Mazda 6, CX-5, and CX-9 models, ensuring precise fitment and reliable braking performance. The rotor’s vented construction allows air to flow between the rotor surfaces, helping to dissipate heat and reduce brake fade during extended use. The directional slotted and drilled surface improves water and debris evacuation, maintaining consistent braking under various driving conditions.

The rotor features a plain disc finish combined with a Geospec silver grey hat finish that includes a rust resistant coating to protect against corrosion and extend service life. With a nominal thickness of 28 mm and a discard thickness of 26 mm, this rotor meets OEM specifications for durability and safety. The 5-bolt hole pattern with a 114.3 mm bolt circle diameter ensures compatibility with the specified Mazda models.
