About the DFC Hi-Carbon Alloy GEOMET Coated Rotor - Drilled Line
This rotor is part of the DFC Hi-Carbon Alloy GEOMET Coated Rotor - Drilled product line by Dynamite Friction. The high-carbon alloy construction enhances rotor strength and wear resistance, while the GEOMET coating provides corrosion protection. The drilled design helps reduce brake fade by improving heat dissipation and gas evacuation during braking, making it suitable for performance-oriented Porsche 718 Boxster and Cayman models.
Technical Details and Specifications
The rotor measures 299 mm in outside diameter and 98 mm inside diameter, with a height of 67 mm. It features five bolt holes with a diameter of 15.42 mm, ensuring proper fitment on compatible Porsche models. The vented rotor type allows air to flow between the rotor surfaces, reducing heat buildup and maintaining consistent braking performance. The nominal thickness of 20 mm and discard thickness of 18 mm provide a clear service life indicator for maintenance.
Applications and Problem Solving
- Compatible with Porsche 718 Boxster, 718 Cayman, Boxster, and Cayman models requiring vented disc brake rotors
- Addresses brake fade caused by excessive heat during spirited driving or track use
- Reduces corrosion and extends rotor lifespan with GEOMET coating
- Improves braking response and pedal feel with high-carbon alloy material
- Maintains structural integrity under high-stress braking conditions
Installation Notes and Tips
Ensure the rotor thickness is measured before installation; replace if below the discard thickness of 18 mm. Confirm bolt hole alignment and diameter (15.42 mm) for proper mounting on Porsche 718 Boxster and Cayman models. It is recommended to inspect brake pads and calipers during rotor replacement to maintain optimal braking system performance.
