This vented disc brake rotor features a directional, slotted and drilled surface designed to enhance braking performance and heat dissipation.

Key Features

• Nominal thickness of 28 mm with a discard thickness of 26 mm for reliable wear limits
• Vented rotor design to improve heat dissipation and reduce brake fade
• Directional slotted and drilled surface for enhanced water and debris evacuation
• Plain disc finish with a Geospec silver grey hat finish for corrosion resistance
• Rust resistant coating to extend rotor life
• Five bolt holes with a bolt circle diameter of 114.3 mm and stud/lug hole diameter of 12.6 mm
• Overall outside diameter of 296 mm and height of 47.3 mm
• Center hole diameter of 64 mm for precise fitment

Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted from Dynamite Friction is designed to meet the braking demands of Acura and Honda vehicles such as the Accord Crosstour, CR-V, Crosstour, and RDX. This rotor features a vented design that allows air to flow through the rotor, helping to dissipate heat generated during braking. The directional slotted and drilled surface improves braking consistency by channeling away water, dust, and gases, which can otherwise reduce braking efficiency.

The rotor’s nominal thickness is 28 mm, with a discard thickness of 26 mm, ensuring a clear wear limit for safe operation. The plain disc finish combined with a Geospec silver grey hat finish and rust resistant coating helps protect against corrosion, extending the rotor’s service life. The rotor is designed with five bolt holes and a bolt circle diameter of 114.3 mm, matching the stud/lug hole pattern of compatible Acura and Honda 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 performance under various driving conditions. The drilled and slotted features are directional, which means they are engineered to optimize the evacuation of heat and debris in a specific rotation direction, contributing to consistent brake pad contact and reduced brake fade. This product line is suitable for drivers seeking rotors that balance performance and durability for daily driving and light performance use.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Acura Accord Crosstour, Honda CR-V, and RDX
• Improves braking performance in wet or dusty conditions by evacuating water and debris
• Reduces brake fade during extended braking periods through vented design
• Helps prevent rust and corrosion with protective coating
• Maintains consistent braking feel with directional slotted and drilled surface

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (26 mm) before installation
• Verify bolt hole pattern and center hole diameter match vehicle specifications
• Clean rotor surface before installation to remove any protective coatings or residues
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Inspect brake pads and calipers for wear or damage during rotor replacement
