Product Line Details

The PowerStop Z26 Street Warrior line is aimed at high-horsepower and modified street vehicles that need stronger braking performance without moving to a race-only setup. KC1127-26 follows that formula with performance pads, drilled and slotted rotors, and calipers finished in Bengal Red for a clean appearance behind open wheels. This kit is a bolt-on brake upgrade for drivers who want a more responsive street brake package on Subaru Impreza and Saab 9-2X platforms.

Detailed Description

PowerStop KC1127-26 is engineered as a front and rear disc brake kit for 2003 Subaru Impreza, 2004-2007 Subaru Impreza, and 2005-2006 Saab 9-2X applications. The kit uses carbon fiber ceramic friction material and performance-grade pads to support shorter stops under demanding street conditions, while the slotted X drilled rotor design helps manage heat and maintain consistent pedal feel. Front rotors measure 277.0 mm outside diameter and use a vented construction; rear rotors measure 266.0 mm outside diameter and use a solid construction. The floating front and rear calipers include one rear piston and two front pistons, with mounting brackets included for both ends. KC1127-26 is a practical upgrade for Subaru Impreza brake kit and Saab 9-2X brake kit shoppers who want a matched front and rear package.
