Power Stop 90-93 Mazda Miata Rear Evolution Geomet Coated Rotor

The GEOMET 360 coating on this Power Stop Evolution rotor is a key detail for keeping your 1990-1993 Mazda Miata's rear brakes looking good and working right. This coating is applied to protect the rotor surface from rust and corrosion, especially during storage or in humid conditions, without adding any thickness that could interfere with how the brake pads make contact. It's a direct bolt-on replacement, meaning it's made to the exact original equipment specifications for fitment, weight, and vane count, so you won't need to modify anything to get it installed.

Power Stop manufactures these rotors to strict tolerances, which helps ensure a smooth and quiet braking experience by controlling factors like disc thickness variation (DTV) and runout. Being dynamically mill balanced also contributes to that smooth operation. You get the original equipment fit and function, but with the added benefit of that anti-corrosion GEOMET coating right out of the box.
