Detailed Description
The Dynamic Friction 633-80037L is a disc brake rotor engineered around the listed Mazda Miata fitments, including 2001-2002 Mazda Miata rear left with Sport & Hard Suspensions and 2003-2005 Mazda Miata rear left. Its 275.5 mm outside diameter, 34.4 mm overall height, and 10 mm nominal thickness provide the dimensional profile needed for the specified application. The slotted X drilled surface and directional design support even pad interaction, while the black-coated hat helps resist visible corrosion in service.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Use part number 633-80037L when matching the correct rotor for the rear left position on the listed Mazda Miata models.
What It Is Used For
- Brake pulsation caused by worn or uneven rotor surfaces.
- Reduced braking consistency from heat-affected rotor faces.
- Corrosion on exposed rotor hat areas.
- Fitment issues when replacing a rear left rotor on the listed Mazda Miata applications.
Installation Notes
Fits 2001-2002 Mazda Miata, rear left, Sport & Hard Suspensions. Fits 2003-2005 Mazda Miata, rear left. Confirm rotor dimensions, bolt pattern, and directional orientation before installation. Verify pad condition and brake hardware wear during service to ensure proper rotor replacement.
Quality Assurance
Dynamic Friction supplies brake components with application-specific engineering and corrosion-resistant finishes for service replacement use. Part number 633-80037L is built to match the listed fitment and dimensional requirements.
