Product Description

The EBC USR1315 Ultimax rear slotted brake rotors are engineered to deliver improved braking stability, reduced noise, and longer service life compared to standard OE rotors. The fine slot design helps clear dust, gases, and debris from the braking surface, ensuring more consistent pad contact and smoother braking performance.

Manufactured from high-quality grey cast iron and finished with EBC's Geomet corrosion-resistant coating, these rotors are built to withstand harsh weather conditions and resist rust buildup over time. The solid rear rotor design is optimized for balanced braking performance on compact and sport-oriented vehicles.

This rotor set is a direct replacement for select 2004-2013 Mazda 3 models equipped with the 280mm rear brake configuration. Proper fitment must always be confirmed by matching OEM rotor dimensions and brake system specifications before installation.
