Detailed Product Features and Specifications

This disc brake rotor features a vented design that improves airflow to reduce heat buildup during braking, which is critical for heavy-duty applications. The surface is both drilled and slotted, allowing for better water and debris evacuation while maintaining consistent pad contact. The directional brake surface ensures the rotor is installed correctly for optimal performance. The rotor’s hat is finished in Geospec silver grey, providing additional corrosion resistance alongside the rust resistant coating applied to the entire rotor. With a bolt hole diameter and stud/lug hole diameter of 16.4 mm and a bolt circle diameter of 139.7 mm, this rotor fits vehicles requiring a 6-bolt wheel pattern.
