I am also adopting a different braking style this season. Earlier on with pretty hard press at first then modulating to less and less g force as the turn approaches. I don't know if it helped my lap times bc I did several other modifications to the car, any, or all of which could have contributed to better times. Interesting to me is that I turned my boost down to 0.96 bar due to excessive wheelspin out of some corners and turned the best lap ever (in constant traffic---there were over 75 cars in my run group). Also interesting to me that my back straight speed on that lap was 152 whereas it used to be the marginally controlable 170+ that Dez mentioned earlier. Let me rephrase marginally controllable------really scary!
I have gone to the PFC 06 this season and really like them. torque feels like almost as much as the 01's I used to run (purely subjective evaluation) but the best part is that after 3 days at Road Atlanta I still have 8mm of pad left on the front. With the old-style braking and 01's, I couldn't have made 3 days without changing pads.
I'm now running Brembo GT all corners and one complaint I have is a longer brake pedal due to the extra volume of all the larger (and greater number of) pistons taxing my stock 996 tt master cylinder. Not a big problem but one worth mentioning for those of you considering that change.

Oranges are the easiest on rotors - BUT they are the weakest by far tend to pad transfer under hard use on our cars. Our calipers & rotors ARE WAY TOO SMALL.
Yellows and Blacks are tough little mothers.

Awesome! Just the news I was hoping for. The local tracks here don't have quite that much speed so I'm hoping I can get a season or two out of the stock calipers before I need to upgrde.
Jeff, yes they will work just fine. What I would be careful of is rotor wear though, I used to get cracks in the stock 330 mm rotors in one day using pagid oranges, which I have heard to be even harder on rotors than any other pagids. I can't say for sure how the blacks will wear on the 4 piston setup because I haven't tried it in that fashion. My first set of blacks was used on 6 pistons.
But your setup idea is just fine. Make sure you vent the front though and run something like motul or AP racing with boiling temp in the 600's or higher. Also depends on your local tracks and your braking style, but make sure you get the best fluid above all.
You short list should be:
Motul/AP Racing or other 600* rated fluid
Custom brake ducting or at the least GT3 RS lower brake ducts
Steel Braded Lines
That should assure you of no brake failure and little to no fade with the front ducts expecially if combined with the lower ducts too.

The problem with Oranges is they pad transfer - MUCH too weak for a 996TT that sees track use.
Now for street/AX/light track use they are ideal.
It's all about the right too for the job ! You must use Yellows and have a TOUGH fluid to have a chance -

I think the Brembos are... Check with Dan at Vivid... He's offering them at a grear intro price!

Has anyone done any research on replacement After Market pads front and rear for the OEM PCCB Pad? The Part Numbers for the OEMs are:
99735184801 (Front) & 99735294800 (Rear) These are the same as the 997 series PCCB pads and superceded the original 996TT PCCB (Gen I) Pads.
Please, I am just asking, I know the local community seems to swear by the highly inflated over priced OEM Pads. I have seen all the comments about If you do not use the OEMs you will wreck your Ceramic rotors. But all propaganda aside, I find it very difficult to believe that there is not a decent after market solution that is in fact better than the OEM set. You can bet your bottom dollar that Porsche does not make the pads themselves. There are far better brake pad manufacturers out there for a variety of solutions. And yes, I understand you cannot use Steel based pads etc. In fact they ideally would need to be far softer than the rotors.
I was just curious. There are a few manufacturers such a EBC that make pads specifically for the Ceramic rotors on the Porsche 997. I would love to get some opinions on them and any others that I am not currently aware of.

Well, give rennstore@comcast.net an e-mail.
They have the P50 PCCB Motorsports pads you need.

I was thinking more genreal brands like EBC etc. They list them for PCCB at reasonable prices, I was wondering of anyone tried them.
Thanks again
