I did some PM on my wife's 03 Outback (oil/filter change, replaced bad front ws/washer pump) this weekend including replacing pads at all 4 corners. I had put in some Wagner pads that I got onsale w/rebate from RockAuto but I never liked them. They required a lot of force to even begin to grab. So, I ordered some Stoptech PosiQuiet pads and they are awesome! At least as good and maybe a little better than stock (though it's been a long time so, I may not remeber that well).
I will be putting Stoptech Street Perf. pads on my WRX wagon soon (front pads).
just an fyi.
