I'm using Godspeed kevlar pads with stock disks at the minute - seem to do the job pretty well without costing the earth. Held up well on track as well.
I'm using Godspeed big brake kit with Blue Stuff pads on my 03 Wagon (same power as PPP). This combination is also very good. I've not had the opportunity for a full track day yet but, I'm confident they'll perform well......so is Ian @ Godspeed!
Another Godspeed user here. I have Godspeed kevlar pads and Godspeed discs. If you do track days you might want different pads but for road use the kevlar pads are great.
