• Directional drilled and slotted surface for improved brake cooling
• Vented rotor design to reduce heat buildup
• Rust resistant coating for extended rotor life
• Geospec silver grey hat finish for corrosion protection and aesthetics
• 5 bolt holes with 13.5 mm diameter and 120.6 mm bolt circle diameter
• Nominal thickness of 26 mm with a discard thickness of 24 mm
• Overall diameter of 305 mm and height of 48.4 mm

Detailed Product Features and Specifications

This DFC Geoperformance Rotor - Drilled and Slotted is designed with a directional surface featuring both drilled holes and slots. This configuration helps to evacuate gases, dust, and water from the braking surface, improving pad contact and reducing brake fade during aggressive driving or high-performance conditions. The rotor is vented, allowing air to flow between the rotor faces to dissipate heat more effectively than solid rotors.

The rotor’s nominal thickness is 26 mm, with a discard thickness of 24 mm, ensuring a clear maintenance threshold for safe operation. 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 further protect against environmental damage.

With a 305 mm outside diameter and 48.4 mm overall height, this rotor fits the specified bolt pattern of 5 holes at 13.5 mm diameter and a bolt circle diameter of 120.6 mm. The center hole diameter measures 70.7 mm, matching the hub specifications for the Cadillac Corvette and Chevrolet XLR models.

About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted product line by Dynamite Friction focuses on delivering rotors that balance performance and durability. Featuring directional drilled and slotted surfaces, these rotors are designed to improve braking efficiency by enhancing heat dissipation and reducing brake fade. The vented rotor design further supports thermal management, making this line suitable for drivers who demand consistent braking performance under varied conditions.

Applications and Problem Solving

• Reduces brake fade during high-performance or spirited driving
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner braking components
• Prevents rust and corrosion with protective coatings
• Maintains structural integrity under repeated thermal stress

Installation Notes and Tips

Ensure the rotor is installed on compatible Cadillac Corvette or Chevrolet XLR models matching the 5-lug, 120.6 mm bolt circle pattern. Verify rotor thickness before installation; replace if below the discard thickness of 24 mm. Clean the rotor surface of any protective oils before mounting to ensure optimal pad contact. Proper torque specifications should be followed for lug nuts to avoid rotor warping.
