• Directional drilled and slotted surface for improved heat management
• Solid disc rotor with zinc silver hat finish and rust-resistant coating
• Nominal thickness of 9 mm with discard thickness at 7.3 mm
• Five bolt holes with 112 mm bolt circle diameter
• Outside diameter of 258 mm and overall height of 55.3 mm

Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to aid in gas and dust evacuation during braking. This design helps maintain consistent pad contact and reduces brake fade under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to moisture and road salt.

Technical Specifications and Features

This disc brake rotor is a solid type, measuring 258 mm in outside diameter and 55.3 mm in overall height. It features a plain disc finish with a zinc silver hat finish that resists rust. The rotor includes five bolt holes with a 112 mm bolt circle diameter and a center hole diameter of 67 mm, ensuring precise fitment on compatible Mercedes-Benz models. The directional slotted and drilled surface improves braking efficiency by allowing heat and gases to escape, which helps maintain optimal braking performance during extended use.

Applications and Problem Solving

• Replaces worn or warped rotors on Mercedes-Benz 190E, 260E, 300CE, 300D, 300E, and E300
• Reduces brake fade caused by overheating during heavy braking
• Improves water and debris evacuation for consistent braking in wet conditions
• Minimizes brake noise and vibration associated with uneven rotor surfaces
• Helps maintain brake pad life by providing a cleaner contact surface

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 7.3 mm before installation. Clean the rotor surface to remove any protective coatings or residues that may affect braking performance. Verify bolt hole alignment with the vehicle’s hub using the 112 mm bolt circle diameter and five-lug pattern. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit and function on Mercedes-Benz vehicles. The rust-resistant zinc silver coating on the rotor hat enhances durability against corrosion. While no specific warranty information is provided, the rotor is designed for consistent performance and longevity when installed and maintained properly.
