There are two sizes of front rotors for the '03 WRX. One is about 10.9" and the other is about 11.4". I bought replacement rotors for mine and got the smaller rotors whereas my car came with the larger rotors. If you check EBC Brake site and download their catalog, they show both sizes.

also, the stock 03 WRX uses 4 (yes I said FOUR) different types of backing plates on the brake pads depending on WHEN your car was built. So you need to take your stock pads out and look at the backing plate to see what type it is....here is a link to the different styles of backing plates for you to match yours up with, then when you order new pads, make sure to order the ones with the correct backing plate.

Here's a link to the different backing plate types. You may want to print it out for future reference.

That's got nothing to do with it. The 10.9" rotors are for non-turbo applications. There are two different pad shapes used for the '03 WRX- and everybody always seems to be given the wrong one regardless of which caliper their car has.

Yes, correct. I attached drawings of each pad size. You can either call your dealer with your VIN to verify, or measure your current pads. Measurements are in mm.

The two larger pads shown are fronts, the smaller are rears.
