Bring smooth, vibration-free stopping back to your roadster with the Dynamic Friction brake rotor 604-80074, a DFC GEOSPEC coated blank front rotor that installs as a direct-fit replacement on the 2017-2020 FIAT 124 Spider and the 2016-2026 Mazda MX-5 Miata. Designed to match the same form, fit, and function as the OEM rotor, it drops into the factory location so worn or warped front rotors can be swapped out cleanly.
If a warped or scored front rotor is the cause of pedal pulsation or brake vibration, this replaces it. Sold individually — this listing is for one rotor; replacing both sides on the axle as a matched pair is recommended for even, balanced braking.
Does this Dynamic Friction brake rotor fit my Mazda MX-5 Miata?
Yes. It's cataloged for the 2016-2026 Mazda MX-5 Miata and the 2017-2020 FIAT 124 Spider. Check the Buyer's Guide tab to confirm your exact year and engine.
Is the 604-80074 a front or rear disc brake rotor?
It is a front rotor, cataloged for the front position on the listed applications.
What is the GEOSPEC coating?
It's a protective finish that provides corrosion protection superior to zinc or conventional painting. The rotor also ships ready to install with no additional pre-degreasing preparation required.
Is this rotor drilled or slotted?
No. It is a blank rotor with a smooth, non-directional finish designed to promote faster break-in and smoother stops.
Should I replace both rotors at the same time?
This listing is for one rotor sold individually. Replacing both sides on the same axle as a matched pair is recommended for even, balanced braking.
