Product Description

The EBC USR1511 rear brake rotors are part of EBC's Ultimax USR series, engineered for performance street and light track use. These rotors feature precision-machined directional slots designed to improve brake pad bite consistency while efficiently removing heat, gas, and debris from the braking surface. This results in more stable braking performance under repeated heavy stops and improved resistance to brake fade.

Manufactured in the UK from high-carbon G3000 cast iron, these rotors are built for strength, heat resistance, and long service life. The vented structure helps maintain cooler operating temperatures, while the corrosion-resistant coating ensures durability in all weather conditions. The design also promotes even pad wear, reducing vibration and maintaining smooth braking feel over time.

This rotor set is specifically designed for rear axle applications on Brembo-equipped Subaru WRX STI models. It is ideal for drivers who want a direct OE-style replacement with improved performance characteristics, especially in spirited driving or performance street environments.
