Appreciate the input - but what I've decided to do is replace the whole system with the Brembo racing system Monoblock 8 piston 4 pad front calipers with 380 mm floating hat slotted rotors and 6 piston 2 pad monoblock calipers for the rear and they all have titanium inserts in the caliper pistons for heat dissipation. The rear rotors have full handbrake capability as well. You can specify Perfomance Friction or Ferodo or Mintex racing pads - we're going with Performance Friction. Brembo just came out with this system recently.
I had heard about just swapping out the rotors - but I opted for what I believe will be better still.

Mark, That is an awsome set up. From my experience and speaking to others that have done the 8 piston Brembo set up have mentioned a soft pedal, and abit slow on the initial bite. Almost like air in the system, but there is none. Could be abit hair raising on the street, but once on the track it's not really and issue with a heavy foot.

Don't know if that's similar or not. The ones I got (installed today) have 6 pistons in the rear.......too late now anyway - but thanks for the lead.

In theory you might be right. The realty is Porsche does not recalibrate the suspension settings if you get PCCB, so the advantages you state are not realized unless the owner spends some more money and does their own suspension tuning. The other advantage of less unsprung weight is sharper turn-in and a more responsive feel to the car. I suspect that there are very few drivers with enough track experience (you won't get it on the street) to be able to really feel 40 lbs difference in unsprung weight.

Street cars are set up softer than ideal for handling on most roads/tracks. This is done for comfort. My experience is that the lower unsprung weight produces a car which feels more like a stiffer sprung car without increasing the unpleasantness of it -- a win/win.

You’ve read the earlier threads here and on Rennteam.com? From your thread title I guess you have.
I am consistently amazed at the number of people here who take the attitude that “Porsche can do no wrong”.
Sounds to me like you are setting up for a legal fight. Is this the case?
Ok, just from reading your post, my impression is that:
1) The lack of stopping is due to boiled fluid and not pad fade. These pads don’t fade on ceramic rotors.
2) The sand you talk about is probably due to ABS damage.
3) The fibres sticking up and being ripped off as well as the high wear rate is overheating of your rotors.
4) The high wear rate of your pads is consistent with what I would expect.
Can you please post photos of the pads and rotors. This will tell us a lot!
Good luck!

First, Mark - let us know @ those brakes. I've heard very positive things.
Second, FixedWing - it's tough without closer examination, but there's an issue here: is the grit (sand) coming from pad wear or is it coming from the ceramic compound failing? I'd sure like to take a close look, and I'd be very surprised if no one @ PAG were also very interested.

JeffES: The "sand" is coming from the ceramic rotor itself. It was starting to disintigrate.
brh986: I could have - but I believe that the brake system I selected will be better overall. We'll see.

What a great review on PCCB!
I'm a reluctant returning customer to Porsche after having not owned a Porsche for 10 years or so. My son and I recently placed orders for 2 GT3s with a March delivery date.
I originally placed the order for mine with PCCB, then changed to no PCCB. Now after reading your post, I'm convinced I made the right decision. Thank-you for the comprehensive and thoughtful post.
Porsche sales people I have encountered either have very little product knowledge, or don't want the truth to interfere with their commission. Asked about PCCB, all I got from the dealer was the factory literature. Surely with all the customer experiences recited on the Internet, they must know what is going on! Unfortunately, this type of response from one's dealer does not inspire trust or confidence.
Thanks to Rennlist for being a great resource!
