If you do the HP+ they will be pretty noisy.
I had Cobra brakes on my 99 GT and went from the OEM PBRs to HPS, night and day difference. Later I got the mod bug and tried the HP+ and couldn't stand the noise. Both were roughly as dusty during street use but the HP+ didn't have very good cold friction and squealed like a pig all the time. I finally went back to HPS and was happy. If you're not actually going to hit the track with this car, I'd stay away from the HP+.
Also, F ceramic pads. (Carbotech excluded)
