  • Compatible with Mazda Miata vehicles
  • Part number 604-80022 for accurate identification
  • Vented disc brake rotor design for improved heat dissipation
  • Outside diameter of 235 mm and inside diameter of 55 mm
  • Nominal thickness of 18 mm with a discard thickness of 16 mm
  • Four bolt holes with a 13 mm diameter each
  • Rotor height of 45 mm

Detailed Specifications and Features

This disc brake rotor features a vented design that enhances cooling during braking, reducing the risk of brake fade. The rotor measures 235 mm in outside diameter and 55 mm inside diameter, fitting precisely on the Mazda Miata brake assembly. With four bolt holes each measuring 13 mm in diameter, installation aligns with factory specifications. The nominal thickness of 18 mm ensures structural integrity, while the discard thickness of 16 mm indicates when replacement is necessary to maintain safe braking performance. The rotor height of 45 mm complements the overall fitment and function within the braking system.

DFC GEOSPEC Coated Rotor Product Line

The DFC GEOSPEC Coated Rotor line by Dynamite Friction focuses on rotors with specialized coatings designed to resist corrosion and extend rotor life. This coating helps maintain rotor surface quality and braking efficiency over time, particularly in environments prone to moisture and road salt exposure. The 604-80022 rotor benefits from this coating, making it a suitable choice for Mazda Miata owners seeking a durable replacement rotor.

Common Applications and Problem Solving

  • Replacement for worn or warped rotors on Mazda Miata models
  • Improves braking consistency by reducing heat buildup
  • Addresses rotor corrosion issues with coated surface
  • Restores proper rotor thickness for safe braking
  • Compatible with brake systems requiring four 13 mm bolt holes

Installation Notes and Tips

Ensure the rotor surface and hub are clean before installation to prevent uneven wear. Verify the rotor thickness before installation; replace if below the discard thickness of 16 mm. Use proper torque specifications on the four 13 mm bolt holes to secure the rotor. The vented design requires clearance for airflow, so confirm compatibility with your Mazda Miata brake caliper setup.

Quality Assurance and Warranty

Dynamite Friction manufactures the 604-80022 rotor to meet OEM standards for fit and function. The DFC GEOSPEC Coated Rotor line includes corrosion-resistant coatings to enhance durability. Warranty details should be confirmed with the distributor or manufacturer, as coverage may vary based on application and usage.
