2018-2021 Subaru STI

EBC RK Series Factory-Drilled Rotors are precision-engineered to deliver reliable braking performance, improved cooling, and enhanced durability for both daily drivers and performance applications. Featuring a cross-drilled and slotted design, these rotors efficiently evacuate gases, moisture, and brake dust during braking, helping maintain consistent contact friction and reducing brake fade—even under demanding conditions.

Key Performance Advantages

• Improved Cooling Efficiency: Drilled holes and slots promote airflow across the rotor surface, lowering operating temperatures.

• Consistent Wet & Dry Braking: Moisture and debris are quickly dispersed for dependable stopping power in all weather conditions.

• Reduced Brake Fade: Enhanced heat dissipation helps maintain braking performance during heavy use.

• Pad Longevity: The rotor design helps prevent pad glazing, supporting longer pad life.

• Sporty Appearance: Performance styling enhances wheel aesthetics.
