I'm 99% sure that they are different.

At least Hawk has different part numbers for SVT focus and mazda3, and I KNOW that SVT focus pads on a mazda3 is bad. Possible that mazda3 pads work on an SVT, but I doubt it. They look close, close enough that hawk sold SVT focus pads as mazda3 pads for a while, before they realized it didn't work.
I've got a NEW set of Hawk pads that I haven't put on yet if you want to look at them sometime. Its gonna be a while til my front brakes wear out though (these things last forever, rear brakes only last me 35k, but fronts are still going at 70k!).
