I'm not dis-satisfied with the stock pads as of yet, more just planning for the future (if needed). And I fgure there is no harm in being able to stop quicker.
I plan on upgrading my suspension before my pads. Just figure that when the stock pads are needing to be replaced I might as well give them a little +1. I only have 4000 miles on my WRX so far, and I don't ride the brakes, so I have time. Just gathering info for now.
