Product Description

The EBC S9KR1485 is a rear axle performance brake kit designed for Subaru GD chassis vehicles including WRX and WRX STI models from 2002 to 2007. It combines EBC's high-friction Yellowstuff brake pads with USR slotted rotors, delivering improved braking response, stronger bite, and enhanced heat management compared to factory rear brake components.

This kit is engineered for drivers who want a noticeable upgrade in rear braking performance for spirited street driving or performance use. The slotted rotor design helps remove brake dust, gases, and debris from the pad surface, while also improving cooling efficiency. The Yellowstuff compound provides strong initial bite even at lower temperatures and maintains stability under repeated heavy braking.

As a direct-fit replacement for the GD chassis rear braking system, installation is straightforward with no modifications required. For best results, this rear kit should be paired with a compatible front brake upgrade to maintain balanced braking performance and overall vehicle stability under aggressive driving conditions.
