Product Description

The EBC S20K1935 Stage 20 brake kit is a complete front and rear OE-style braking solution designed specifically for 2008-2014 Subaru Impreza WRX and WRX STI platforms. It combines EBC Ultimax2 brake pads with RK series rotors to deliver smooth, quiet, and consistent braking performance for daily driving and performance street use.

The Ultimax2 compound uses aramid fiber technology to reduce brake dust and noise while maintaining strong, stable stopping power under turbocharged AWD performance demands. The RK rotors feature a Geomet anti-corrosion coating that helps prevent rust buildup and ensures long service life in all-weather driving conditions including rain, snow, and aggressive road use.

This kit is engineered as a direct OE replacement for compatible WRX/STI brake systems, restoring balanced braking across all four wheels while improving pedal feel, durability, and overall stopping confidence for performance-oriented driving.
