About the DFC Hi-Carbon Alloy GEOMET Coated Rotor - Drilled Line

This rotor is part of the DFC Hi-Carbon Alloy GEOMET Coated Rotor - Drilled product line by Dynamite Friction, which focuses on combining high-carbon alloy materials with GEOMET coating technology. The high-carbon alloy enhances rotor strength and wear resistance, while the GEOMET coating provides corrosion protection. The drilled design further assists in maintaining braking efficiency by allowing heat and gases to escape, reducing the risk of brake fade.

Technical Specifications and Features

The rotor features a nominal thickness of 30 mm and a discard thickness of 27.4 mm, indicating the minimum thickness before replacement is necessary. Its vented construction improves airflow between the rotor surfaces, helping to dissipate heat generated during braking. The 320 mm outside diameter and 67 mm inside diameter are matched to the specific hub and caliper dimensions of the Infiniti QX30 and Mercedes-Benz CLA250 and GLA250 models. The five bolt holes, each 15.3 mm in diameter, ensure a precise and secure mounting.

Applications and Problem Solving

• Replacement for worn or warped rotors on Infiniti QX30 and Mercedes-Benz CLA250/GLA250
• Improves heat dissipation to reduce brake fade during extended use
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps maintain consistent braking performance under varied driving conditions
• Prevents corrosion-related rotor damage with GEOMET coating

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the discard thickness of 27.4 mm. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify bolt hole alignment and torque specifications according to the vehicle manufacturer’s guidelines. Proper bedding-in of the rotor and brake pads is recommended to achieve optimal braking performance.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for the listed Infiniti and Mercedes-Benz models. The GEOMET coating provides enhanced corrosion resistance, contributing to the rotor’s longevity. Warranty details should be confirmed with the distributor or manufacturer, as they may vary by region.
