Product Description

The EBC USR1344 Ultimax slotted brake rotors are engineered for high-performance Subaru STI applications, delivering improved braking consistency, reduced noise, and enhanced thermal control. The fine-slot design helps clear gases, dust, and debris from the brake surface, maintaining strong and predictable pad contact even under repeated heavy braking.

Manufactured from high-grade cast iron and finished with EBC's corrosion-resistant Geomet coating, these rotors are designed to withstand high thermal loads and resist rust formation in all weather conditions. The vented construction improves cooling efficiency, making them suitable for spirited road driving and performance use.

This rotor set is a direct OE replacement for select 2005-2017 Subaru Impreza WRX STI models equipped with the Brembo 325mm front brake system. Proper fitment must always be confirmed by matching OEM rotor dimensions and brake package configuration before installation.
