About the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that provide improved heat dissipation and reduced brake fade through a combination of drilled holes and precision slots. This design supports directional braking surfaces to optimize performance and maintain rotor integrity under demanding conditions. The zinc silver hat finish and rust resistant coating extend the rotor's service life, making it suitable for Audi models that require both performance and durability.

Detailed Product Description

This disc brake rotor features a 350 mm outside diameter and a nominal thickness of 28 mm, with a discard thickness of 26 mm to ensure safe replacement intervals. The rotor’s surface is both drilled and slotted in a directional pattern, which helps to evacuate gases, dust, and water from the braking surface, improving braking consistency and reducing the risk of brake fade. The zinc silver hat finish and rust resistant coating protect against corrosion, which is especially important for vehicles like the Audi Q8 e-tron and S7 Sportback that may be exposed to varying weather conditions. The rotor includes five bolt holes with a 112 mm bolt circle diameter, compatible with the specified Audi models.
