Detailed Product Features and Specifications

This disc brake rotor features a plain disc finish combined with a vented design to optimize cooling during braking. The drilled and slotted surface pattern is directional, which helps channel away gases and debris, maintaining consistent pad contact and reducing brake fade. The rotor’s nominal thickness is 22 mm, with a discard thickness of 19 mm, ensuring safe replacement intervals. The hat section is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rotor includes a rust resistant coating to protect against environmental wear. With four bolt holes spaced on a 100 mm bolt circle diameter and a center hole diameter of 55 mm, this rotor is specifically designed for compatibility with Toyota Prius C, Yaris, and Scion iQ models.

About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted product line focuses on delivering rotors with enhanced heat dissipation and braking efficiency through a combination of drilled holes and slots. This design supports improved pad bite and helps maintain braking performance under demanding conditions. The vented rotor construction further aids in cooling, making this line suitable for drivers seeking consistent braking on daily driven vehicles like the Toyota Prius C, Yaris, and Scion iQ.

Applications and Problem Solving

• Reduces brake fade during extended or heavy braking
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust and gas buildup for consistent pad contact
• Protects against rust and corrosion for longer rotor life
• Restores braking performance on Toyota Prius C, Yaris, and Scion iQ models

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 19 mm before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 100 mm bolt circle diameter and 4-bolt pattern. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction to maintain optimal performance.
