Late 03-05 WRX StopTech Brake Upgrade Packages

There are multiple brake caliper combinations for the 2003 WRX model year. The only way to ensure you are buying the right setup for your car is to measure the pads already on the car and use the picture on the left as a guideline.

The pads on this page are for 2002-2003 WRXs with the same pad dimensions as the image to the left (D929 front and D1004 rear pads)..

Perfect for the budget minded WRX owner, the StopTech Power Slot Stage 1 kit is a great first step to take your braking performance up a notch. The StopTech Power Slot Stage 1 Upgrade Kit includes stainless steel lines, StopTech performance pads, and three bottles of Motul RBF600 DOT4 performance brake fluid. The front & rear stainless steel brake lines improve pedal feel and reduce the amount of time between applied pedal pressure and actual deceleration by preventing the expansion that your WRX's stock rubber flex lines allow.

Putting StopTech performance brake pads on all four corners helps provide you with higher resistance to fade, higher maximum operating temperature, and better initial bite to allow consistent deep braking into corners. Motul RBF600 DOT 4 brake fluid increases both wet and dry boiling points and prevents boiling under the most severe operating conditions. The Stop Tech Power Slot Stage 1 Brake Upgrade Kit is recommended for the WRX that is primarily used on the street and might see the occasional autocross; if you plan on doing track events we suggest picking up a set of pads more appropriate for that task.

The StopTech Power Slot Stage 2 Brake Upgrade package for the WRX utilizes the stock caliper as a starting point, but improves all other aspects of the braking system. This comprehensive kit from StopTech Power Slot includes StopTech performance brake pads, stainless steel lines, Motul RBF600 DOT4 performance brake fluid, and StopTech Power Slot SportStop slotted rotors for all four corners.

StopTech Power Slot SportStop slotted rotors are direct OEM replacements and will fit the OEM calipers. SportStop slotted rotors won't drastically improve the braking distance of your WRX, but they do cool off faster and when used with a high performance brake pad, they will cut a few feet off your 60-0. Putting StopTech performance brake pads on all four corners helps provide you with higher resistance to fade, higher maximum operating temperature, and better initial bite to allow consistent deep braking into corners. Motul RBF600 DOT4 brake fluid increases both wet and dry boiling points and prevents boiling under the most severe operating conditions. The StopTech Power Slot Stage 2 Brake Upgrade Kit is recommended for the WRX that is primarily used as a daily driver but might see the occasional autocross; if you plan on doing track events we suggest picking up a set of pads more appropriate for that task.
