Its directional surface features both drilled holes and slots, which help to evacuate gases, dust, and water from the braking surface, improving pad contact and reducing brake fade. The rotor’s vented construction allows for better heat dissipation, which is critical during heavy braking or towing applications.\u003c\/p\u003e\u003cp\u003eThe rotor has a nominal thickness of 25 mm and a discard thickness of 23 mm, ensuring durability and safety over its service life. The zinc silver hat finish combined with a rust-resistant coating protects the rotor from corrosion, extending its lifespan in various driving conditions. With six bolt holes sized at 15.7 mm diameter and a bolt circle diameter of 135 mm, this rotor is designed for precise fitment on compatible vehicles.\u003c\/p\u003e\u003ch2\u003eDFC Brake Rotor - Drilled and Slotted - Silver Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled and slotted surfaces with corrosion-resistant finishes. This product line is tailored for drivers who require reliable braking performance with enhanced heat management and durability.
