Detailed Product Features and Specifications
This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented design that allows air to flow between the rotor surfaces, reducing heat buildup during braking. The rotor’s surface is both drilled and slotted in a directional pattern, which helps to evacuate gases, dust, and water, improving brake pad contact and reducing the risk of brake fade. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, ensuring a long service life before replacement is necessary.
The rotor’s hat is finished in zinc silver, providing corrosion resistance, while the entire rotor is coated with a rust-resistant layer to extend durability in various driving conditions. With six bolt holes and a bolt circle diameter of 104 mm, this rotor is designed for a secure and precise fit on compatible vehicles.
