I've been reading up on the PCCB's in anticipation of a forthcoming order, but found most of the info to be second hand - aka people who had a friend who had a friend who had PCCB's and encountered some kind of problem.

As far as I've been able to tell, there are two generations, Gen-I in pre-05 and Gen-II in post-05. Gen-I failed at ~15,000 miles, while I haven't heard too much about the Gen-II problems which are rated to something like 185,000 miles. I realize that opinions are very strong about this, in both directions, so I'm looking for more hard facts and direct comparisons then just general thoughts on the matter.

My personal reasons for thinking about adding PCCB's to my order is mainly the lack of brake dust, which drives me crazy, but saving weight and the potential for increased durability and resilience is attractive as well. Car will be tracked once a month, and auto-cross about the same.

 

if you are going to do 12 track days a year plus autocross you will probably be happier with steel brakes...I have Gen II PCCB's, have been through a couple sets of pads...11,000 miles and 15 track days...rotors look fine..but I came from a momentum car and I am not hard on brakes but I am just as fast as the guys who go through brakes like they were made out of chocolate...depends on your driving style but autocross will be hard on brakes so I would suggest steel...you might want to get a report from someone with Gen II that has more track days than I do and is harder on brakes

 

Thanks for the info. Can you comment on daily driving with the PCCB's in comparison to steel? Sounds, feel, dust, etc.

 

they are less effective when they are cold so I try to late brake with them on the street so I get some heat into them..they do make a little more noise when they are cold...absolutely no brake dust...although you still get typical road/tire dust...I like no dust, less unsprung weight and the fantastic braking when I need it....I love em...so I can't say anything negative about them

 

I had PCCB's in my 2005 launch car . I loved them and they had no brake dust and worked very well . I felt that they were not worth 8K to buy though and in my 2007 C2S I did not get nor did I get them on my Turbo . The steel Porsche brakes are outstanding and the price is quite good compared to the PCCB .
When I upgraded to 700 Hp I felt the steel brakes needed an upgrade and I could have selected the PCCB . I didn;t . Instead I went with the Brembo and comparing ALL the brakes I like these the best. Installed it cost nearly the equal as the PCCB (a little less) but I feel great response and reduced fade . Someone on the 997tt forum asked (paraphrasing) " what difference does it make ro slow down a car ?" My reply was that if a car can accelerate so fast it need an equal quick response in stopping .
PCCB's are yoir best brakes out of the box .
Aftermarket makes better though IMO .
Steel are great and free .

You can't go wrong with any.

 

+1..yrralis1 makes a good point..the $8K original cost can pay for all your other track mods...GT3 seats, harnesses, roll bar and lightweight track wheels/tires...when it comes time to replace the steels you can do the Brembo's...when my Pccb's have bit the dust I will go with Brembo's myself

 

The first time I drove a car with PCCB"s was in a friends GT3 on the track at 10/10ths. That drive convinced me to sell my M3 and get a Porsche. On the track the PCCB's were the best brakes ever. My 2006 C2S has the brakes system from the Turbo. They're not PCCB's but they are bigger than the standard C2S brakes and they do the job.

Did you upgrade your brakes? All 997 S have the big red's. These are the same brakes as the 996TT's.

I run 100% OEM iron rotors and stock brake pads, have done a 18 track days and about 18000 miles total on my car. I have worn out 1 set of Rotors and two sets of pads. Very good life for the work that I do with the car. I have never lost my brakes on the track and never found the limit of the brakes. I change my brake fluid regularly.

 

My car is a CPO. The original owner ordered the car with 2nd gen. PCCB's and didn't like them. Since he was a long-term customer, the dealership replaced the PCCB's with brakes from the Turbo. The Turbo brakes are larger, they use a 6 piston caliper with 42% more pad area. The rotors cool more also, about 14% more, actually better than the ceramics... just not as light. I would have preferred the PCCB's, but the Turbo brakes are pretty awesome. The Turbo brakes are not the same brakes that come with the standard C2S.

I would love to get some hard data from porsche sport driving school on how their PCCB equipped cars are doing.

To the OP make sure you do a brake flush and use a top quality brake fluid and don't let the pads get below 50% without changing them.

 

I did not know that one cold replace the C2S brakes with the Turbo steel brakes. In fact I am not sure how it may change the car's drive with the added weight . I had thought about selling my Turbo brakes but abandoned the idea figuring that i would have very limited buyer offers . They are still sitting at the dealership . Come to think of it .. I need to pick them up.

 

I'm an SCCA racer. I have the track record in my class at my home track. I can drive a car at 10/10ths.

With Turbo brakes my C2S is a well balanced car that can stop, lap after lap, like it had PCCB's (well, almost).

The car is a fabulous track toy.

Suncoast sells a GT3 conversion kit using GT3 calipers and Turbo hangers and Rotors.

$2500 and a few hours to get it done.

 

Great comments. Similar thoughts have come from the Ferrari group with regard to CCB's on the F430. $18K option until 08.

A new set of rotors and pads (all 4) is $38 to $40k. Ouch !

 

How difficult would it be to say, buy the PCCB and switch them out for some steels on the few days that I do track? I've changed out plenty of rotors and pads on cars before, but some cars are harder then others.
