The CGT brakes are much larger and have better cooling than the GT2/3/TT. The factory drivers (Timo and Sasha) were hammering the brakes pretty hard during the CGT taxi ride in Leipzig. They would go out for a two or three lap ride with plenty of hard braking and no cool down time between rides.

Yeah, I went to Leipzig for that, but don't have any idea how often the rotors were replaced on those two cars.

 

Do I understand correctly that some people are running front steel and rear Pccbs? carl

 

I have 12,750 on mine with no problems.

That is accurate. I got a set of front cup disks as I was going to do the same mod. But I decided to tempt fate by not installing them before heading to the track. I figured if they are going to fail they are not worth a damn and I don't want them anyways. Why should I let the next owner (assuming I was ever get rid of the car) enjoy the benefits of the option I paid for.

 

Sloth are you now running steel fronts and PCCB rears. Is the brake balence the same? carl

 

I run steel front and PCCB rears, no noticeable difference in brake bias or performance yet.

Guy, do you track the car with that setup. carl

 

Yes, as does a good friend of mine with the same set-up on his GT2. I only changed mine recently, so have only done one trackday. He has done several including the Nurburgring.

Guy

 

Guy,how long have you had the setup on? How long has your friend run the setup? thanks carl

 

No, still running the full PCCB setup and the rotors are in good shape, but like I said the pads were toast.

In these post Sebring shots you can see just how hot the pads got. Since the photos I have changed the pads and driven another 1000 miles.


Cracks, but not quite chunking. The rust is from an earlier carwash.


I still have the set of cup disks sitting unused in my garage.

 

Here's a set of PCCBs of my friends GT2 that went bad in 7,000 miles.......





See much of the surface has simple disappeared! The same happend to my first set and is starting to happen to my 2nd set.

ah tyson babeee --

pretty inaccurate, in that replacement in a Strad is not necessary:

1] Stradale rotors no issues whatsoever under very heavy track use by some of my pals

2] Ferrarri actually guarantees our cars on the track, unlike GMC/Porsche. track failure? no problem ferrai pays.


[no credence given to "friends' car story above]

 

Guy, did they still work ok? I wonder if maybe if they just don't look like that after hard use. I notice that the fronts do develop a much rougher surface after a while but does it affect the performance?. I'm surprised that I've never seen a TSB on rotor ware. usually Porsche try's to cover there *** on everything. carl

 

No they were terrible and dangerous.

In fact the car failed the braking test and was therefore refused an MOT Certificate (the Governments annual Ministry Of Transport test of road-worthiness in the UK). The car was not legally allowed on UK roads until these were removed and replaced with new discs (which were steel).

There are many cases of PCCB failure on this board and the rotors actually start to fall apart with holes appearing in the surfaces and it takes on the appearance of lava rock.

This is only occuring to those people who use the car for what Porsche designed it, the many people who never brake hard, exceed 100mph or track it will probably never suffer PCCB problems while driving down Rodeo Drive.........
