2018-2021 Subaru STI

Upgrade your braking system with EBC factory-drilled rotors, engineered as a direct-fit OEM replacement that combines everyday reliability with performance-focused design. Each rotor is precision machined and fully balanced to ensure smooth braking, reduced vibration, and consistent pedal feel right out of the box.

These rotors feature a modern silver-grey Geomet coating applied during the casting process, delivering superior corrosion resistance compared to traditional black coatings. The result is long-lasting protection against rust and environmental wear while maintaining a clean, premium appearance.

Cross-drilled holes are strategically engineered to expel gases, moisture, and brake dust generated during braking. This improves pad contact, maintains consistent stopping power in wet or dry conditions, and helps prevent pad glazing. The design also enhances cooling efficiency, reducing heat buildup and minimizing brake fade during demanding driving.

Manufactured and precision-machined in the UK, these rotors are built using high-carbon materials for durability and dependable performance. While popular among performance enthusiasts for their aggressive look and improved response, they’re equally well suited for daily drivers seeking dependable braking with a performance edge.
