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. This configuration helps maintain optimal braking performance by improving heat dissipation and reducing brake fade. The directional surface pattern is engineered to channel gases and debris away from the pad surface, which is particularly beneficial for vehicles like the Mercedes-Benz C and E-Class models that demand reliable stopping power under varied driving conditions.

Detailed Product Description

This disc brake rotor is designed with a nominal thickness of 22 mm and a discard thickness of 19.4 mm, ensuring a long service life before replacement is necessary. The vented rotor type allows air to flow between the rotor surfaces, reducing heat buildup during braking. The directional drilled and slotted surface improves pad bite and helps evacuate water, dust, and gases, which can otherwise reduce braking efficiency. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rust resistant coating on the rotor surface helps protect against environmental damage, extending the rotor’s durability.

Applications and Problem Solving

• Compatible with Mercedes-Benz C250, C300, C350e, C400, E250, E300, and E350 models
• Reduces brake fade during aggressive or repeated braking
• Improves braking performance in wet or dusty conditions
• Helps prevent rotor warping caused by excessive heat
• Minimizes corrosion and rust buildup on braking surfaces

Installation Notes and Tips

Ensure the rotor is installed with the directional surface pattern oriented correctly according to the vehicle’s rotation direction. Verify that the bolt hole pattern (5 holes, 112 mm bolt circle diameter) matches the vehicle hub. Check rotor thickness before installation to confirm it meets or exceeds the discard thickness of 19.4 mm. Proper torque specifications should be followed when securing the rotor to avoid warping or uneven wear.

Quality Assurance

Dynamite Friction manufactures the 830-63118R rotor to meet or exceed OEM specifications for fitment and performance on Mercedes-Benz C and E-Class vehicles. The rust resistant coating and Geospec hat finish contribute to long-term durability. Warranty information is available through Dynamite Friction and should be confirmed at the point of purchase.
