DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a vented design to optimize braking efficiency. The drilled and slotted surface helps evacuate gases and debris, while the vented construction aids in heat dissipation. This rotor line is designed to meet the demands of performance-oriented driving and heavy-duty applications, making it suitable for various Mercedes-Benz SUVs.

Detailed Product Description

This disc brake rotor is constructed with a plain disc finish and a Geospec silver grey hat finish that includes a rust-resistant coating to extend rotor life and maintain appearance. The rotor’s directional slotted and drilled surface improves pad bite and helps channel water and brake dust away from the contact area. With a nominal thickness of 22 mm and a discard thickness of 19.4 mm, the rotor maintains structural integrity and safety throughout its service life. The vented design allows air to flow between the rotor faces, reducing heat buildup and minimizing brake fade during extended use.

Applications and Problem Solving

• Compatible with Mercedes-Benz GL350, GL450, GL550, GLE400, GLS350d, GLS450, and GLS550 models
• Addresses brake fade caused by excessive heat during heavy braking
• Reduces brake dust accumulation on rotor surface
• Improves wet weather braking performance by channeling water away
• Helps prevent rotor warping through enhanced heat dissipation

Installation Notes and Tips

Ensure the rotor is installed on the correct side to maintain the directional surface orientation. Verify bolt hole alignment with the 5-lug pattern and 112 mm bolt circle diameter. Clean the rotor surface before installation to remove any protective coatings or residues. Check rotor thickness before installation to confirm it meets or exceeds the discard thickness of 19.4 mm. Proper torque specifications should be followed for mounting bolts to ensure secure fitment.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM specifications for fit, form, and function. The rust-resistant coating and durable finishes contribute to long service life. While specific warranty details are not provided, the product is designed to comply with industry standards for safety and performance on Mercedes-Benz vehicles.
