Warren, thanks for the link. About ccm-specific pads, what are your thoughts about them being even further classified based on the type of ccm disc...brembo, SGL, or ST. What I'm trying to ask is can a ccm-specific pad for a brembo disc be used w/o problems on an ST disc?
I have used RSC1(same as RSX1 maybe?), RSC3, and RS29. I didn't care for the RSC1, but the RSC3 and RS29 feel pretty good. I haven't run the setup long enough to truly know if they are significantly shortening the life of my rotors though. I would like to try the W007 but it's too expensive to get addicted to lol.
Please let me know if you develop a pad suitable for ST's...in a GT3 fitment!

I ask the same question about Cialis...

Included in the “GT3 Price//Options” Section of Ian Kuah’s excellent GT3 article in Excellence Magazine, November 2013, Pages 58 / 59, tells me that Porsche recognized the 10X Replacement Cost Factor of PCCB Brakes vs Steel ($25,000 vs $2,500) made them unsuitable for heavy Track use.

Pg. 58:
“On the other end of the options spectrum is the Ceramic Brakes System ($9,210). Sure PCCB’s expensive, but we want the best for our GT3, including an almost 40-lb savings in unsprung weight.
Porsche has made the decision a little easier, too, offering a slick way to swap in the standard steel brakes when desired, say for track days when we wouldn't want to fry our very costly ceramic rotors and bespoke pads.”

Pg. 59:
“(Note: the Ceramic and Steel Brakes can be swapped easily for track day use.
The Disc Diameters are different, but the calipers can be spaced out easily to accommodate the larger disc. The Calipers and Disc off-set is common between the two systems.)”

I thought the GT3 CCM has the largest diameter @410mm F / 390mm R, so unless he is talking on different models, if it's GT3 (PCCB std), shouldn't it be swapped down to a smaller rotor, than using a spacer and swap it up to a bigger rotor.

Am I missing something here?

FastLaneTurbo

That seems logical to me also. I've E-mailed PCNA requesting they contact PAG for clarification, but mainly to find out if these conversion "Kits" actually are available,
and if they are, their price and delivery. Obviously PCCB GT3 and TTS owners
who frequently track their cars would be very interested. The Porsche dealers and Parts Suppliers I've contacted have no information of this availability from PAG. I'll post the reply as soon as I receive it.

FLTurbo: this would be terrific news if the magazine description was just a typo. I'd love to be able to throw the 380mm steels on there w/ the PCCB system's calipers set. That is, assuming there wouldn't be 1) a performance issue of any sort w/ the set-up and 2) that it wouldn't look weird on the wheel w/ a huge gap where the rotor is only going into 1/2 or 2/3 of the caliper.

That article has come up a few times. We have had a customer's 991 in our shop for the last 2 weeks in order help Warren at Racingbrake develop their new offerings that will be released soon. This GT3 was equipped from the factory with the PCCB setup. (410mm front and 390mm rear) There is definitely no spacer between the front caliper and spindle which can be removed in order to lower the PCCB caliper down onto the smaller (380mm) iron rotor. The calipers are direct bolt to the spindle. Same with the rear.

Now it could be that what is available is a spacer that would allow iron brake equipped models to space that caliper out to fit the larger CCM rotor. I can't say if this is actually viable either as I don't have a steel equipped car to play with. I think it is a moot point in any event as how many 991 owners will want to pay extra for CCM rotors if they already purchased a car with a iron setup. But this will be an option none the less. We will be releasing different packages very shortly which will address all possible options.

I would be amongst the iron equipped willing to upgrade to a ccm solution other than Porsche's which melts on track and is impossibly expensive to replace. I would want to fit the 390mm CCM discs of surface transforms that used to be a direct replacement for 997.2 PCCB fronts.

If they are reasonably priced these could be a good solutions providing PCCB benefits but durability and possibility to refurbish if needed.

I have a very complex and technical question.

Which one squeaks more when driving at slow speeds? This drives me absolutely crazy.

Mika911

On my steels with RSL1 or Dixcel pads I have zero squeak, even though it primarily gets tracked. What are you using?

BrntRubber

my pcar hasn’t arrived yet, but I have had squeaking on my M6 Gran Coupe and it drove me nuts.

I like matching the stitching with my calipers and the touring only comes with the option of red iron breaks or yellow PCCBs. Yellow isn’t available so I was leaning towards red as it will match the interior, save a big chunk of cash and will look good against satin black with guards red pinstripe if so went that way. This is provided the iron brakes will not squeak. I will do little tracking with this vehicle.

I did have a close call once at high speed in an F430 and the stopping power amazed me. If the stopping power is far greater on the PCCB then that is a serious consideration. If there isn’t a big difference I will save the cash.

GT3 KSA

I drive a 435 gran coupe and that noise drives me crazy too. Sometimes i brake hard just for that sound to go away. I have not noticed it on my GT3 (owned for almost 2 years now) and i have tracked the car like 3 or 4 times. I have the standard brakes.

PS if you really want to match stitching with calipers you can do deviated stitching on the touring in yellow

NMM991

I have had zero squealing on 2010 and 2015 GT3s, a 2016 GT3 RS and a 2012 Cayenne. On my wife's 2016 Cayenne it was so bad that the dealer replaced all the brake pads; even they were frustrated with the issue. Why some cars and not others -- my personal opinion is that my wife has her foot on the brake too much and most of her driving is around town. I tried full threshold braking from 100 mph, backing up in a large parking lot with the brakes on to no avail. I would still buy PCCBs on any new cars.

Carbon Ceramics without a doubt have superior braking performance to that of the iron brakes. That being said, the iron brakes can have no squeaking issues and a lot of times that depends on how well the pads were bedded in on the car and what pads are being used. If you wanted to try the iron brakes as red matches your interior options, know that I can set you up with a set of Surface Transforms carbon ceramic rotors that will fit your red calipers for about half the cost of the PCCB rotors. They perform better and last 4-5 times longer as they are refurbishable compared to the PCCBs which are not.
