Overview of Dynamite Friction DFC GEOSPEC Coated Rotor - Drilled

The Dynamite Friction DFC GEOSPEC Coated Rotor - Drilled (part number 624-46021) is engineered for reliable braking performance on Cadillac and Chevrolet vehicles, specifically the Corvette and XLR models. This vented disc brake rotor is designed to maintain optimal braking efficiency under demanding conditions.

  • Vented rotor design for improved heat dissipation
  • Drilled surface to reduce brake fade and improve water dispersion
  • Nominal thickness of 26 mm with a discard thickness of 24 mm
  • Outside diameter of 330 mm and inside diameter of 70.7 mm
  • Five bolt holes with a diameter of 13.4 mm for secure fitment
  • Height of 49.3 mm ensuring proper alignment and clearance

Detailed Product Features and Specifications

This disc brake rotor features a vented design that enhances airflow between the rotor surfaces, helping to reduce heat buildup during braking. The drilled pattern further assists in dissipating heat and preventing water accumulation, which can improve braking response in wet conditions. With a nominal thickness of 26 mm and a discard thickness of 24 mm, this rotor provides a balance between durability and performance. The rotor’s 330 mm outside diameter and 70.7 mm inside diameter are matched to the specific requirements of Cadillac Corvette and Chevrolet XLR models, ensuring precise fitment. The five bolt holes, each 13.4 mm in diameter, allow for secure mounting, while the 49.3 mm height maintains proper rotor positioning relative to the caliper.

About the DFC GEOSPEC Coated Rotor - Drilled Product Line

The DFC GEOSPEC Coated Rotor - Drilled line from Dynamite Friction focuses on rotors that combine a protective coating with drilled surfaces to enhance braking performance and rotor longevity. The coating helps resist corrosion and wear, while the drilled design aids in heat and moisture management. This product line is tailored for drivers seeking rotors that maintain consistent braking under varied driving conditions, particularly for performance-oriented vehicles like the Cadillac Corvette and Chevrolet XLR.

Applications and Problem Solving

  • Compatible with Cadillac Corvette and Chevrolet XLR models requiring vented, drilled rotors
  • Addresses brake fade caused by excessive heat during aggressive driving
  • Improves braking performance in wet or humid conditions by dispersing water
  • Helps prevent rotor warping through enhanced heat dissipation
  • Suitable for replacing worn or undersized rotors to restore braking efficiency

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 24 mm before installation. Properly clean the rotor surface to remove any protective coating residue before mounting. Verify bolt hole alignment with the vehicle’s hub using the 13.4 mm bolt hole diameter and five-hole pattern. It is recommended to inspect brake pads and calipers during rotor replacement to maintain balanced braking performance.
