Detailed Product Features and Specifications
This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a plain disc finish and a zinc silver coated hat to resist rust and corrosion, extending the rotor's service life. The rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. The directional surface pattern, combining drilled holes and slots, helps evacuate gases, dust, and water from the braking surface, improving pad contact and braking consistency.
With a nominal thickness of 22mm and a discard thickness of 20mm, this rotor meets precise wear limits to ensure safe operation. The rotor's 5-lug bolt pattern with a 112mm bolt circle diameter and 15mm stud hole diameter matches the factory specifications for the Mercedes-Benz 300SD, ensuring proper fitment and installation.
About the DFC Brake Rotor - Drilled and Slotted - Silver Product Line
