Product Description

The EBC USR7172 Sport Slotted Rear Rotors are engineered for Mazda RX-8 owners seeking improved braking consistency, enhanced cooling efficiency, and quieter operation compared to traditional aggressive slotted rotors. EBC's USR narrow-slot design helps maintain a clean brake pad surface while efficiently evacuating gases, moisture, and debris during repeated braking cycles.

Manufactured from premium SAE G3000 grey iron and finished with EBC's corrosion-resistant Geomet coating, these rear rotors provide excellent durability for spirited street driving, canyon use, and daily performance applications. The vented construction improves thermal management while the precision-balanced design helps minimize vibration and uneven wear. Designed as a direct OE replacement, the USR7172 rear rotors install using factory mounting points without modification.
