Casey, I am confused. The pics look like the stock Red S brakes. The 09 S brakes are the same as the 2005-08 brakes so I am not understanding what you are getting at when you say the 09 is underbraked? I track at Sebring and swap out the stock fluid for either Motul600 or Castrol SRF, put in either Performance Friction PF97 or Pagid RS29 Yellows and when those race pads get up to temp the car will stand up on it's nose when threshold braking. The stock pads work fine for the street and autoX and light DW work.
The following brake comments for the 997.2 was posted by Michael on another thread....
"Lets clear this up, because there have not been a lot of facts printed about this.
The 2009 Standard Carrera has front discs which are 330MM in diameter, and which are 34mm thick. That is an increase from the 2008 model of 12mm in diameter.(1)
The rear of the 2009 standard carrera now measure the same 330mm in diameter as the front, up from 299mm in the previous model.(1) These discs are 28mm thick. theses are now 4mm thicker than the previous model as well.(2)
The brake discs on the 2009 Carrera S are...identical to the standard Carrera. 330mmx34mm up front, and 330mmx28mm in the rear,(1).
The difference between the Standard car and the S for 2009 is solely in the caliper. The S has red ones...and they are of a different design, which I would GUESS is a stiffer design for even better brake feel. But I really don't know, as nothing I have makes any reference to the difference other than what I have written. There is NO mention anywhere that the pad size is different on the S vs non-S. It would not surprise me to find out that they have different part numbers though, as they each have a different caliper design, and possibly pad material is made for a higher temperature on teh S than the standard car, but this is pure speculation. I would love to have a photo comparison. Perhaps as we get into track season, and people start changing their pads we can see something like this.
Hope that helps.
Michael

Lockie, sorry you miss understood me...I knew the 09 Carrera and S version use the same rotors now and it is just th caliper is different. I thought Casey had a 09 S already and said the new 2009 997S was under braked, which confused me because the 09 S has the same brakes as the 05-08 S.

thanks! Mike
Sorry Mike, I read it again ....Its been a long day.....I should put the computer away and head to bed... My 997.2 arrives in 2 weeks and its like waiting for Christmas.
I wonder if the sensation might be the "new" 997S feels under-braked because the performance levels on all fronts increased (DFI engine, Sport PASM / LSD), while the brakes remained exactly the same...
MDrums... It is a carrera s and Mike Levitas, our owner and pro driver believed that the car(having more power across the board than a 996 GT3) deserved better brakes. The new braking system on the base car is a pretty trick system... This car is capable of carrying a lot more speed into the corners than the previous S car so that along with our plans of 550hp made us spring 6k for the better braking system. I would be happy to elaborate more if you would like.

Casey, thanks for the explaination. For the track what pads are you going to use? Do you feel that for the track the 997.2 with race pads such as Perf Friction PF97 or 01 and Pagid RS29 Yellows would not help the braking at the track? I ask this because I feels that these pads alone would be a huge advantage for more stopping power at the track.
Yes I agree that with you planned 550hp you will need bigger and more powerful brakes.
That does seem to be an aggressive set up and will probably get a lot of the job done... depending on how hard you drive it might be the perfect solution.

lots of phone calls/pm's/emails regarding future power upgrades... our main "kit will likely be available come mid-may. when we start dynoing the project i will make sure it is covered here.

Sorry for bumping but 550 @ the wheels is quite the amount of power. I'm guessing you are not getting there with a supercharger.
I remember e-mailing wondering if you would develop a turbo kit for these cars and was told flat out no. Did plans change for some reason?
550Hp at the wheels ...this is crazy power for a bolt on system Car like this would put to shame a 997 TT, but reliability would be ...Itīs alot more power than stock, so all engine internals and other parts are exposed to highly streesed forces. I really want to see the final result of TPC system and will follow it step by step
