Detailed Product Features and Specifications

The 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 arranged directionally to help evacuate gases, dust, and water, which can improve brake pad contact and reduce brake fade. The rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, ensuring a clear maintenance threshold for safety. The zinc silver coating on the hat provides rust resistance, extending the rotor’s service life. With 5 bolt holes and a bolt circle diameter of 114.3 mm, this rotor fits securely on the Nissan 240SX hub assembly. The center hole diameter measures 68.1 mm, and the stud/lug hole diameter is 12.8 mm, matching OEM specifications.
