I have Hawk HPS pads on the front and rear as well as Brembo blank rotors all around on my 98 SVT. I've only put about 100 miles on since I installed them so I don't have any feedback just yet. Bought all from TireRack.
I do have some sort of high pitched vibration that is only audible and is coming from the front every once in a while when I go to accelerate. If I tap the brakes the sound stops. So I think I may take the front brake back apart and make sure I have everything well greased. Probably do that when I put the car up to replace a bushing in the rear suspension within a couple weeks.
