Dynamite Friction 830-31056D Disc Brake Rotor - Front Left

Overview of Dynamite Friction DFC Geoperformance Rotor

The Dynamite Friction DFC Geoperformance Rotor - Drilled and Slotted (part number 830-31056D) is engineered for BMW M5 models requiring reliable braking performance. This vented disc brake rotor features a directional, slotted, and drilled surface designed to enhance heat dissipation and maintain consistent stopping power under demanding conditions.

• Compatible with BMW M5 vehicles
• Vented disc brake rotor with 345 mm outside diameter
• Directional, slotted and drilled surface for improved brake pad bite and cooling
• Plain disc finish with Geospec silver grey hat finish
• Rust resistant coating to reduce corrosion
• Minimum discard thickness of 30.4 mm

Detailed Product Features and Specifications

This disc brake rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction, designed to meet the specific braking demands of performance vehicles like the BMW M5. The rotor’s vented design allows for better airflow, reducing heat buildup during aggressive braking. The directional surface pattern, combining drilled holes and slots, helps evacuate gases, dust, and water from the braking surface, improving pad contact and reducing brake fade.

The rotor’s hat is finished in Geospec silver grey, providing a durable and corrosion-resistant surface, complemented by a rust resistant coating on the disc itself. With an outside diameter of 345 mm and a discard thickness of 30.4 mm, this rotor maintains structural integrity and performance over its service life.

Applications and Problem Solving

• Improves braking performance for BMW M5 models under high-stress driving conditions
• Reduces brake fade caused by heat buildup during repeated stops
• Minimizes corrosion and rust on the rotor surface for longer service life
• Enhances pad bite and braking response with slotted and drilled design
• Maintains consistent braking feel with vented rotor construction

Installation Notes and Tips

When installing the Dynamite Friction 830-31056D rotor on a BMW M5, ensure the rotor is mounted with the directional surface pattern oriented correctly to optimize airflow and debris evacuation. Verify the rotor thickness before installation to confirm it meets or exceeds the discard thickness of 30.4 mm. Proper torque specifications should be followed for mounting hardware to avoid rotor warping.
