Product Details

Part number 4512-80103 is engineered for drivers servicing the front brakes on the Mazda MX-5 Miata and Fiat 124 Spider. The coated rotors are machined to tight tolerances, inspected for critical dimensions, and balanced where required to support consistent pedal feel and quieter operation. The included DFC 5000 Advanced pads are formulated for stable friction performance, while the hardware kit is built to restore proper spring tension and caliper movement in the brake assembly. This makes 4512-80103 a practical choice for a front brake refresh on the Mazda MX-5 Miata and Fiat 124 Spider.

Common Brake Issues This Kit Addresses

• Rotor rust and surface corrosion
• Brake noise from worn or fatigued hardware
• Uneven pad wear caused by caliper movement
• Longer stopping distances from worn friction material
• Brake vibration related to rotor finish or balance

Installation Notes

Confirm front brake configuration before ordering, especially on 2021-2022 and 2016-2020 Mazda MX-5 Miata models with Brembo front brakes excluded from this application. The rotors are shipped dry and ready for installation, which reduces prep time during service. For best results, clean the hub mounting surface, inspect caliper slides, and follow the pad bed-in procedure recommended for ceramic brake pads.

Quality Assurance

DFC GEOSPEC rotors are manufactured to OE specifications, finished with a non-directional surface, and inspected for balance and critical dimensions. The rotors carry a 12-month warranty against defects in material and workmanship.
