Product Details

The DFC GEOSPEC rotor line is built to OE-style G3000/G11H18 cast iron specifications and machined to tight tolerances for durability, reliability, and stable braking performance. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry, ready-to-install design eliminates the need to clean oil from the rotor before assembly. The 5000 Advanced ceramic pads are formulated for stable friction and quicker initial bite, and the included hardware is engineered to restore proper spring tension and caliper movement on the rear brakes of the Mazda Miata. Part number 4512-80052 is a practical choice for a rear brake refresh on 1990-1993 Mazda Miata models.

Common Brake Issues This Kit Can Address

• Rear brake noise from worn or corroded hardware
• Uneven pad wear caused by fatigued clips or caliper movement
• Rust buildup on exposed rotor surfaces
• Reduced braking smoothness from worn rear rotors and pads
• Longer stopping response from aged friction materials

Installation Notes

Before installation, inspect calipers, slide pins, and brake fluid condition to confirm the rest of the rear brake system is in serviceable shape. The rotors are shipped dry and do not require oil removal, and the coating is removed naturally by the pad friction during normal use. For best results, follow proper brake bedding procedures after installation on your Mazda Miata rear axle. Verify fitment by year and position before ordering.

Quality Assurance

DFC GEOSPEC rotors are inspected for balance and critical dimensions, then checked against OE specifications. Each rotor includes a 12-month warranty against defects in material and workmanship. The 5000 Advanced pads are post-cured and assembled with NVH-focused shims, and the hardware kit is built with OE-style attention to form, fit, and function. Part number 4512-80052 is designed as a complete rear brake service solution for 1990-1993 Mazda Miata vehicles.
