Details on the DFC GEOSPEC Coated Rotor - Drilled Product Line

The DFC GEOSPEC Coated Rotor - Drilled line from Dynamite Friction focuses on rotors with specialized coatings and drilled patterns to reduce heat buildup and resist corrosion. This product line is tailored to provide consistent braking performance and durability, particularly for high-performance and luxury vehicles such as Mercedes-Benz SUVs and crossovers. The coating helps extend rotor life while the drilled design aids in maintaining cooler brake temperatures during operation.

Technical Description and Specifications

This disc brake rotor features a vented design with a height of 54.6 mm, allowing air to flow between the rotor surfaces to dissipate heat effectively. The rotor’s outside diameter measures 375 mm, with an inside diameter of 67 mm, ensuring proper fitment and compatibility with the specified Mercedes-Benz models. The 5 bolt holes, each with a diameter of 15.2 mm, align precisely for secure mounting. The nominal thickness of 36 mm and discard thickness of 33.4 mm provide clear service limits for maintenance and replacement.

Applications and Problem Solving

• Replacement rotor for Mercedes-Benz GL450, GL550, GLE43 AMG, GLE400, GLE500, GLE550e, GLS550, and ML550 models
• Addresses brake fade caused by excessive heat during heavy braking
• Helps reduce rotor warping and cracking through vented and drilled design
• Improves braking consistency and pedal feel
• Resists corrosion and extends rotor service life with specialized coating

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (33.4 mm) before installation
• Clean mounting surface and hub to prevent uneven rotor seating
• Torque bolts to manufacturer specifications for secure fitment
• Inspect brake pads and replace if worn to maintain optimal braking performance
• Perform a bed-in procedure after installation to ensure proper rotor and pad contact
