DFC 900-80072 Rear Hi-Carbon Alloy Geomet Coated Brake Rotor for 2016-2025 Mazda MX-5 Miata & Fiat 124 Spider

Fits 2016-2025 Mazda MX-5 Miata and 2017-2020 Fiat 124 Spider.

Dynamic Friction Company (DFC) Hi-Carbon Alloy brake rotors are engineered for drivers who demand superior thermal stability and long-term durability. These rear rotors are cast from premium G3000/G11H18 metallurgy, increasing the carbon content to better handle the heat cycles of spirited driving while minimizing the risk of warping or cracking. Each rotor features a Geomet coating, providing a high-performance barrier against corrosion on all non-friction surfaces.

To ensure a smooth, vibration-free pedal feel, every rotor is 100% precision mill-balanced and machined to strict tolerances. The fine-turned 16 RMS finish facilitates a faster break-in period between the pad and rotor, while the original equipment (OE) vane configuration maintains proper airflow for maximum heat dissipation.
