The SICOM refurbish relates to the pccb, not RB. In fact every time we try to bring this refurbishment opportunity up, RB tries to bury it with a page of copy, I understand they are a sponsor but it's so flagrantly abusive sometimes that I don't understand why the mods haven't caught on. Anyway, learning about how to extend the life of the pccb is key for me and others

I'm on the same page as you Alex. SICOM is relevant to the PCCB discussion, i'm also interested in it as well.

Correct me if I'm wrong, but you don't track your car much at all, so I really don't think you have to worry about pccb life. You will be in the camp where pccb works well and have no problems with wear

I believe that $3k refurb was for one pair only, IIRC. And a full set of 4 OEM iron rotors is more like $2500 shipped online.

And I wouldn't put any faith in a "refurb" until multiple folks run them through their full refurb life to see how far they go vs. stock.

After 3 trackdays and 700km (3 trackdays spa, Dijon and mangy cours in france) mine start to wear strongly. What do you conisider a lot of trackwork ?
pccb track users on 991 gt3 or rs when did you start to have significant on wear on your pccb ?

thanks

I run an RS (991) and after 7 track days, tests show rotors down 40% on average but 60% in some locations. Since four of these days were in 40 deg F weather, I am appalled at the poor wear properties.

Of course, the pads are only down one or two mm each. Unbelievable. That's like $30k / year for light track duty.

I am thoroughly disappointed.

Alain & Lolo. Very disappointed to hear your experiences with PCCB in track.

Agree with Alex about vendor "interference" on these threads. Mention the words @brake pads" for example and you'll get a flood of vendors posting.

Asco

Wow, that is a huge to difference to other guys who posted around 30 track days with same wear (please correct me if I am wrong).

Would be interested in hearing the SICOM experience as well.

orthojoe

Fellas, we need to understand that 30 track days for one guy is 3 days for another. Drivers and tracks are not equal. For whatever reason, this is something that people have a hard time comprehending. Any statement about consumable lifespan must be qualified with track and lap time. Otherwise, it really means nothing.

SanDiegoDavid

I'm very interested in hearing about OEM refurbishment as well.
Joe has a good point, but loosing that much in only 7 days seems excessive.

Asco

Joe please understand me correctly and I am not questioning your knowledge on this topic as you have way more of it than myself. It just seems that gap between 3 and 30 days is to large for similar wear.

orthojoe

My statements should always be questioned!

Keep in mind that the 3 days stated did NOT say that they were done in 3 days. They were 40%-60% done. While not apples to apples, the wear indicator on my 987 boxster spyder started to show at 5 days. They weren't done at 5 days, but it was enough to pull them off and switch to iron. I have to imagine that the new gen 3 pccb rotors are at least 2 times more durable, but even at four times the durability of gen2 pccb, it's too costly for me when you can get iron AP rotors that will last 30-40 track days for me.

Guys,

I am an intermediate driver and have a ST kit on my 2016 car. I try to brake early and drive as smooth as possible within my skill set. I run Cup2s.

To date the rotors and RSC1 pads have 1442 track miles and 12 track days.

The track days were at Laguna Seca, Thunderhill, and COTA.

The front rotors have no apparent visual wear. The rear rotors are showing slight grooving.

The pads are about half worn, with about 6 mm remaining. The pads wedge, and have been flipped once. I checked inner and outer pad wear.

I am going to change the pads soon as a precaution (heat transfer and resultant increase in rotor surface oxidation). The supplier, Autoquest, recommends running no less than 40 % total pad thickness.

ST supports refurbishment at about 2,000.00 US shipped to the UK. Refurbishment up to 5x . I am hoping to get 25 track days out of this set.

LoloM

There we are, now I have changed my pads to "save the disc". Did just 60km on a small track (ouest parisien), speed of 200km/h max, the pads are new but cooked and some very bad scratches appear everywhere even increasing while street driving.
brakes do a strong "hum" when I first apply strongly which did never happen to me before on pccb. Here are some pics of the discs. What is your opinion guys ? And has anyone already had it on their 991 ? Thx

I have recently done this dance w PCNA and 2 dealers on my GT4. MY RS arrives this week and will no doubt have the same issues.

FIRST and most importantly the way the rotors are measured is critical. The new process uses a fancy machine that is like and ultrasound unit. Not sure what it measures . Not all dealers have it and fewer know how to use it , yet. Measuring on the car without further precaution yields potential very high wear readings because of the metal shield behind the rotor. Option 2 is to take the caliper off and measure where the caliper goes because there is no shield. Best option , to get a real measurement and base line ,is to take the rotor off and measure on a wooden bench.

My experience is Porsche is not throwing rotors at people so buyer beware. ( Most of us apparently don't know how to drive ). I received new pads on fronts from PCNA as they seemed to be breaking apart and grooving the rotors. You hear a very distinctive grinding sound when they get that way. After one Sebring trip and 2 Homestead trips I am hearing it again and will likely call Clark at Apex for the Girodisc option so I don't lose anymore sleep thinking about a 30 k brake job.


Cheers
