Detailed Product Features and Specifications

The DFC Brake Rotor - Drilled from Dynamite Friction is a vented disc brake rotor specifically designed to fit Mercedes-Benz CL550, S400, and S550 models. The rotor features a 335mm outside diameter and a 67mm inside diameter, ensuring proper fitment and compatibility. Its vented design enhances airflow between the rotor surfaces, which helps dissipate heat more effectively during braking. The drilled rotor surface aids in reducing brake fade by allowing gases and debris to escape, while also improving wet weather braking performance.

With a nominal thickness of 32mm and a discard thickness of 30mm, this rotor maintains structural integrity and safety throughout its service life. The five bolt holes, each with a diameter of 15.2mm, align precisely with the vehicle’s hub for secure installation. The rotor height of 64.5mm ensures proper clearance and fit within the brake assembly.

DFC Brake Rotor - Drilled Product Line Information

The DFC Brake Rotor - Drilled line by Dynamite Friction focuses on rotors that combine vented construction with drilled surfaces. This design balances heat management and braking responsiveness, making it suitable for performance-oriented applications and daily driving. The drilled feature helps maintain consistent braking under various conditions, while the vented core supports longer rotor life by reducing thermal stress.
