Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted from Dynamite Friction is designed to meet the specific braking requirements of select Mercedes-Benz vehicles. Its vented construction allows air to flow through the rotor, reducing heat buildup during braking and helping to maintain consistent stopping power. The directional drilled and slotted surface improves water and debris evacuation, which helps reduce brake fade and maintain pad bite under demanding conditions.

The rotor’s nominal thickness of 22 mm ensures durability, while the discard thickness of 19.4 mm provides a clear service limit for safety. The rust resistant coating and Geospec silver grey hat finish protect against corrosion, extending the rotor’s service life and maintaining appearance. With 5 bolt holes and a bolt circle diameter of 112 mm, this rotor is engineered for precise fitment on compatible Mercedes-Benz models.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on delivering rotors with enhanced surface designs that improve braking efficiency and rotor longevity. This product line combines drilled holes and slots in a directional pattern to optimize heat dissipation and debris removal, making it suitable for both daily driving and more demanding conditions. The rust resistant coating and specialized hat finish are standard features that contribute to the rotor’s durability and corrosion resistance.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves braking performance in wet or debris-prone environments
• Minimizes rotor surface glazing and pad wear
• Prevents rust and corrosion on rotor surfaces
• Ensures consistent braking response for Mercedes-Benz C250, C300, C350e, C400, E250, E300, and E350 models

Installation Notes and Tips

• Verify rotor thickness before installation; replace if below discard thickness of 19.4 mm
• Ensure proper torque on all 5 lug bolts with 112 mm bolt circle diameter
• Clean rotor surface before mounting to remove any protective coatings or contaminants
• Check compatibility with vehicle model and year to confirm fitment
• Inspect brake pads and calipers during installation for optimal performance
