Product Description

The EBC S2KR2338 is a rear brake upgrade kit designed for Subaru WRX and WRX STI VA chassis platforms. It combines EBC Greenstuff 2000 performance brake pads with USR slotted rotors to deliver improved braking response, better heat management, and more consistent stopping performance compared to OEM brake components.

The slotted rotor design helps maintain a clean friction surface by removing gases, dust, and debris during braking, which reduces fade and improves consistency under repeated high-load braking. The Greenstuff compound enhances initial bite and pedal feel while maintaining low dust characteristics suitable for daily driving.

This kit is engineered as a direct OE-style replacement for compatible Subaru rear brake systems, ensuring straightforward installation without modifications. It is ideal for drivers seeking a balanced upgrade for daily driving, spirited road use, and occasional performance driving while maintaining OEM reliability.
