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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction features rotors designed to improve brake cooling and reduce fade through a combination of drilled holes and precision slots. The zinc silver hat finish and rust resistant coating help extend rotor life by protecting against corrosion. This product line is tailored for drivers seeking enhanced braking performance and durability on compatible Mercedes-Benz vehicles.

Technical Description and Specifications

This disc brake rotor is vented to allow better airflow and heat dissipation during braking, which helps maintain consistent stopping power under demanding conditions. The drilled and slotted surface design aids in removing brake dust, gases, and water from the rotor surface, improving pad contact and reducing the risk of brake fade. The rotor’s nominal thickness is 25 mm, with a discard thickness of 22.4 mm, ensuring clear service limits for safety. The zinc silver hat finish and rust resistant coating provide additional protection against corrosion, which is important for maintaining rotor integrity over time. The rotor features a 5-bolt pattern with a 112 mm bolt circle diameter, matching the specifications required for Mercedes-Benz 300CE, 300E, 300TE, 400E, E320, and E420 models.

Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz 300CE, 300E, 300TE, 400E, E320, and E420
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Rust resistant coating prevents corrosion-related rotor damage
• Directional drilled and slotted design enhances wet weather braking performance

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22.4 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify the 5-bolt pattern and 112 mm bolt circle diameter match your vehicle’s hub specifications. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The rust resistant coating and zinc silver hat finish contribute to long-term durability. While no specific warranty information is provided, the product is designed for reliable performance on compatible Mercedes-Benz models when installed and maintained according to manufacturer guidelines.
