Its no secret that Subaru dropped the ball in many areas when it comes to stopping power. Coming from cars with bigger brakes (2 evos and a 370z) I wasn't exactly expecting eye snapping stopping power anyway though, so I wasn't to high in my expectations.
I had installed the good ridge phantom lines quite a while back, and while I felt an improvement. I wasn't wowed by any means. After 15k miles of very unstable braking my bday was coming up and I just told my wife I wanted pads. I seriously considered the hp+, but many complained about a squishy pedal feel with them and many here and on other sites felt the st's were just a better overall pad, especially considering the very high cost of the hawks.
I went of course with the st pads. I did all 4 though I know many only do fronts. It wasn't to much more and the little more cost was no big deal.
Install was of course easy enough (NOTE!! The rear pads only have the wear indicators on one side, so don't be alarmed like I was), but the pads did not come with any grease which caused me to have to stop and go out to my local hardware. Got them all done without much issue and the next day bedded them in per st's instructions of 60-10 mph stops in a row 10 times before they could cool. I do not track my car, nor have I ever done so, therefore I am not any sort of expert on this. However, during these stops I experienced zero fade and with each stop the brakes seemed to bite even harder. The pedal feel was a little better, but with that firewall flex, it still does not bite right away without guving the pedal more of a push. Not a super big deal as the pads stop very very well and my confidence in them is much higher now.
Overall I would recommend them for the money and I will be doing another brake bleed to make sure no air somehow got into the lines during the pad swap. Well worth the money overall, just make sure you have or order grease.
