DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on delivering rotors with enhanced cooling and braking efficiency through a combination of drilled holes and precision slots. This design helps reduce brake fade by improving heat dissipation and maintaining a clean pad surface. The vented rotor construction further supports thermal management, making it suitable for daily driving and moderate performance applications on Acura and Honda vehicles.

Detailed Product Description

This Dynamite Friction disc brake rotor features a plain disc finish with a Geospec silver grey hat finish that provides corrosion resistance and a clean appearance. The rotor’s 5-bolt hole pattern with a 114.3 mm bolt circle diameter matches the factory specifications for compatible Acura and Honda models including the Accord, BR-V, Civic, CR-V, CSX, Element, and ILX. The directional drilled and slotted surface improves braking response by allowing gases, dust, and water to escape efficiently, reducing the risk of brake fade and maintaining consistent pad contact.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Improved heat dissipation to reduce brake fade during extended braking
• Enhanced braking performance in wet conditions due to directional slots and drilled holes
• Corrosion resistance to extend rotor lifespan in humid or salty environments
• Restores proper braking feel and pedal response on compatible Acura and Honda models

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness of 21 mm before installation
• Verify bolt hole pattern and diameter match vehicle specifications (5 bolts, 12.6 mm diameter)
• Clean rotor surface before installation to remove any protective coatings or residues
• Use proper torque specifications for lug nuts to avoid rotor warping
• Inspect brake pads for wear and replace if necessary to ensure optimal rotor performance

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The rust resistant coating and precision machining ensure durability and consistent braking performance. While specific warranty details are not provided, Dynamite Friction products typically adhere to industry quality controls to support reliable operation on Acura and Honda vehicles.
