The part numbers i gave are for 2 peice.
Put it this way,i could warp a set of front discs at a race meet/hard track test day with the standard front discs,the 2 peice would last until worn out or cracks got to big.

Back to the pads chat - I had Pagid blues on my 964 RS wannabe.
They were ok on the road but I found that small particles of the pad did bond to the discs slightly after a serious track workout at Bedford. The result was quite a bit of judder through the steering wheel whilst braking on the drive home. This happened even though I braked hard and late on track (not dragging the brakes) and did a full cool down lap (of the entire GT circuit) after every 20 minute session.
I moved onto the new improved EBW yellowstuff R pads which are hopeless on road and track.
I'm also looking for the holy grail of an acceptable road and track pad but have yet to find it. Pagid Blues are ok but don't stand up to a real hammering on track in my experience.

You probably all know that most of the GT3 brigade use RS29s (I use them front and back). They squeal like crazy. They also tend to look awful because they crack. However, this is considered normal/acceptable but I replace them once they get to half worn because the performance drops off dramatically at that stage. We tend to short out the pad wear sensors. For some reason the RS29 pads I buy for the front do have the drilling for the pad wear sensors but not the rears. I've been told that the sensors get too hot anyway so best to remove them.

I always find the brake pad threads interesting whether on this or other forums as almost to a one the Pagids are regarded as fantastic and EBCs as rubbish.
The odd thing is whilst I agree that Pagids can be great, save for the hideous cost and almost badge of honour levels of squeal, I have also found EBCs to be good.
I used Redstuff on my 993 Carrera and currently use redstuff in my 993 RS. Both are used on UK trackdays and the 'Ring and I seem to have good fade free brakes from cold with not much brake dust.
I used the EBCs on my XR challenge car over 5 sesons of racing , like alot of other competitors in that series to good effect.
Interestingly a good friend of mine who races a Caterham also says EBCs get a bad write up with the Caterham people.
What is the issue with them?
I can only assume I am not braking hard enough or something.

The reason a disc would explode is because cracks have presumably gone to the edge of the disc. Cracks emanate from the holes on the drilled discs and are not meant to exceed 5mm. I replaced the drilled front discs with solid floating discs because I wasn't prepared to change the discs after only 3 or 4 track days! (some people manage to drive quickly and be gentle but most of us can't/aren't). I don't think the pads are likely to make much difference (I may be wrong) - I think the problem is people either not realising that their discs are cracking or choosing to ignore it (I've seen GT3 discs that I consider dangerous, i.e. where cracks are getting very close to the edge of the disc).
I inherited a car with a known brake replacement "issue".
The front discs had cracks 10+mm long, and the backs had cracks around 4mm long.
I replaced them all, but was told that the old discs might be re-used for the "odd" trackday ?
Whilst I am happy for them not to be a total write off, what damage can an exploding disc wreak ?

That's a very very starnge advice as on track you're putting on the heaviest load the discs will ever see on that car, and if it's not fit for road, then it's definately not fit for track!!
I had a rear disc with small cracks all over which is quite ok, and later I booked the car in to have them changed because some of them were reaching the rim, and a few were joining the holes after a trackday. On my way to the garage I felt a loud grinding/groaning noise at a traffic light a few miles from the garage, I practically limp there without touching the brake much and just about made it there. Found a large split on a rear disc from centre to rim with .5mm step on it! Can you imagine that on a track at the end of a long staright! Just imagine damaged caliper, wheel, folllowed by hub, shaft, suspension etc etc, then probably a mighty big crash into the barrier!
Could nt agree more , or simply one side bites and the other doesnt cos the disc is nt there!
SIMPLE RULES OF DRIVING DONT MESS WITH BRAKES ! AND ON TRACK DEFINITELY DONT MESS WITH BRAKES !!!!
Porsche do traditionally leave larger safety margins than some but is nt it common sense if the cracks are nera the edge or double prescribed margin [5mm] then its past dustbin day ?
If ur rev limiter says 7400rpm, do u remove the limiter and try to 8400 to see if it will burst ?
