Detailed Product Features and Specifications
This DFC Brake Rotor - Drilled and Slotted - Silver is designed with a vented rotor type to improve airflow and reduce heat buildup during braking. The rotor’s surface combines drilled holes and slots, which help evacuate gases, dust, and water, contributing to better brake pad contact and reduced brake fade. The directional surface pattern ensures the rotor is installed correctly for optimal performance.
The rotor’s nominal thickness is 28 mm, with a discard thickness of 26 mm, indicating when replacement is necessary to maintain safe braking. The zinc silver coating on the hat provides corrosion resistance, extending the rotor’s service life. The rotor features five bolt holes with a 114.3 mm bolt circle diameter, matching the stud/lug hole pattern of INFINITI J30 and Q45 models. The center hole diameter is 68 mm, and the stud/lug hole diameter is 12.7 mm, ensuring precise fitment.
