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, which features high-carbon alloy construction combined with a GEOMET coating. The drilled design aids in heat dissipation and helps reduce brake fade, while the GEOMET coating provides corrosion resistance to extend rotor life. These rotors are engineered to meet the specific braking requirements of performance vehicles like the Porsche Boxster and Cayman.

Detailed Product Description

The 920-02039 disc brake rotor is a vented type rotor with a nominal thickness of 24 mm and a discard thickness of 22 mm, ensuring a balance between performance and longevity. Its 299 mm outside diameter and 98 mm inside diameter are designed to match the brake system specifications of Porsche Boxster and Cayman models. The rotor features five bolt holes with a diameter of 15.4432 mm, allowing for secure mounting. The 67 mm height supports proper fitment and compatibility with the vehicle’s caliper assembly. The vented design improves airflow, helping to maintain optimal operating temperatures during braking.

Common Applications and Problem Solving

  • Replacement for worn or warped rotors on Porsche Boxster and Cayman
  • Improves heat dissipation to reduce brake fade during spirited driving
  • Addresses rotor corrosion issues with GEOMET coating
  • Restores braking performance and pedal feel
  • Compatible with OEM brake systems requiring vented, drilled rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22 mm before installation. Clean the rotor surface to remove any protective coating residue before mounting. Verify bolt hole alignment and torque bolts to manufacturer specifications. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Check for proper clearance with calipers and suspension components during installation.

Quality Assurance and Warranty

Dynamite Friction manufactures the 920-02039 rotor to meet strict quality standards for fitment and performance on Porsche Boxster and Cayman vehicles. The GEOMET coating enhances corrosion resistance, contributing to longer service life. Warranty details should be confirmed with the product documentation or supplier, as they may vary.
