Product Description

The EBC S20K1778 Stage 20 brake kit is a complete front and rear OE-style braking solution designed specifically for the 2005 Subaru Legacy and Outback 2.5i platforms. It combines EBC Ultimax2 brake pads with RK series rotors to deliver smooth, quiet, and consistent braking performance for daily driving conditions.
