Product Description

The EBC RK418 Ultimax OE-style rotors are engineered as direct factory replacements for the front braking system of the 1990-1994 Mazda Miata. These rotors are designed to restore original braking performance while offering improved durability and corrosion resistance compared to worn OEM components. Built to OE specifications, they provide reliable, consistent braking performance for daily driving and light spirited use.

Manufactured from high-quality G3000 cast iron, these rotors feature a precision-machined surface and strict quality control standards to ensure smooth operation and minimal runout. The Thermic Black coating protects against rust and corrosion, helping extend rotor life and maintain a clean appearance. Their vented design helps dissipate heat efficiently, reducing the risk of brake fade under repeated braking conditions.

This part is specifically confirmed to fit 1990-1994 Mazda Miata (NA chassis) equipped with the 1.6L inline-4 engine. It is designed for the front axle and works with OEM calipers and brake pads without modification. Fitment is confirmed through verified retailer specifications for these model years.
