There are multiple brake caliper combinations for the 2003 WRX model year. The only way to ensure you are buying the right pads 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 (D721 front and D770 rear pads).
- These pads fit all 2004-2005 WRX models and 2003 WRX models with the D929/D1004 caliper combination.
- If you have a 2003 WRX, you need to measure the dimensions of your stock brake pads to determine which calipers you have. Use the diagram above as a reference. Please call before you order if you have any questions.
