Detailed Product Description and Specifications

This Dynamite Friction rotor is a vented type, which means it features internal vanes between the rotor faces to improve airflow and reduce heat buildup during braking. The drilled surface further aids in heat dissipation and helps prevent brake fade by allowing gases and debris to escape. With a nominal thickness of 32 mm and a discard thickness of 30 mm, this rotor maintains structural integrity and performance throughout its service life. The rotor measures 322 mm in outside diameter and 67 mm inside diameter, designed to fit the specific brake assembly of the Mercedes-Benz CLS400. The bolt pattern includes five holes with a diameter of 15.3 mm, ensuring secure mounting and compatibility.

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 surfaces to enhance braking efficiency and rotor longevity. The coating helps resist corrosion and wear, which is particularly beneficial for vehicles like the Mercedes-Benz CLS400 that require consistent braking performance. This product line balances durability with thermal management to meet the demands of modern disc brake systems.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz CLS400
• Improves heat dissipation to reduce brake fade during heavy braking
• Addresses rotor corrosion issues with protective coating
• Helps eliminate brake noise caused by uneven rotor surfaces
• Restores braking performance affected by rotor thickness below discard limits

Installation Notes and Tips

• Ensure rotor thickness is above the discard thickness of 30 mm before installation
• Verify bolt hole alignment with the 5-hole, 15.3 mm diameter pattern
• Clean mounting surfaces to prevent uneven rotor seating
• Torque bolts to manufacturer specifications for secure fitment
• Inspect brake pads for wear and replace if necessary to optimize rotor performance
