Product Description

The EBC USR7738 USR Series Front Sport Rotors are designed for Mazda compact platforms including Mazda 3 and CX-3 applications. The narrow-slot USR design improves braking consistency by clearing heat, gases, and debris from the rotor surface while maintaining quieter operation than aggressive slot designs.

Manufactured in the United Kingdom from high-grade G3000 cast iron, the USR7738 rotors are precision-machined for OE-level balance, durability, and fitment accuracy. The vented construction improves thermal stability under repeated braking, helping reduce fade and maintain consistent pedal feel in daily driving conditions.

This front rotor set is a direct replacement for 2014-2019 Mazda 3 and 2016-2020 Mazda CX-3 models equipped with the standard 295mm front brake system. When paired with EBC performance pads, it delivers improved stopping response, reduced noise, and longer rotor life for everyday use.
