Hello,

Been looking around for a 2007 GT3 with higher miles...

Plan is to DE the car 5-6 times a year. Keep it long term....

From what I recall when the PCCB came out, the rotors were suppose to last a lifetime. Seems its not the case....
Pads need to be changed at 50%?

Please fill me in on the PCCB over steel. Running cost, how delicate are they, what should i check for a car that has them and 30k-50k miles.

Worst case scenario, best case scenario?

Thx!!

Please... Found a car but it has PCCB and I am not too sure...

Nothing wrong with PCCB..

They are perfect for the street and will last forever.
How long they last on track will depend how tough you are on the brakes.
If you are an amateur like me just be sure your pads are +50% and you'll be fine.
I have 50.000km with 4000km track miles and my rotors are like new.

If the pccb's are toast just replace with Iron rotors and that's it.
You will even have the bonus to have the big brake caliper in the front.

Cheers

Ok, thats good to know I can just put steel rotors on!

Why the 50%, does it have to to with heat transfer to the caliper?

delanobe

To be sure the pccb's are ok just slide with you finger on the rotor, must be smooth as glass

delanobe

The 50% is because of peace of mind and only if you track the car

Don't sweat this, if the pccb are good, great, with the .1 PCCB a steel swap is easy, use the .2 rotors, the cup rotors, or PFC, or brembo... you get 380mm fronts which is a plus over a non pccb .1. Most will say if you track the car put steels on an put the pccb rotors on the shelf.

Just had my PCCBs pads replaced all around after having fronts flipped 4 DE events ago. Rotors still in great shape. 17.5K miles . Plan for PFC or Brembo fronts and OEM turbo rear steel rotors when mine need replacing.
50% is safety margin because of front tapering. Flip them when appropriate to maximize pad life.
Adding .2 rear brake ducts soon to improve cooling.

P.J.S.

You can also locate 2nd hand pccb replacements that are like new and avoid the $20k replacement costs

Street use: thumbs up. No brake dust, and they'll last forever - as advertised.

Just keep your eye on the brake pad wear, because you will destroy the rotors if you wear the pads all the way out.

Track use: thumbs down. Swap the rotors out, or buy a car with steel brakes. Unless you drive like a complete pansy.

LOL, very funny. I guess I know how you drove my car before I bought it.

Lots of hard track miles on these reported by others. If you don't plan on goingto the track 50-70 days, stick w/PCCB. They're fine. I regret switching to steel. I don't go enough, and the temps and tracks up here are nowhere near the braking torture of places like Sebring, FL (no camber, fast straights, tight corners).

chakka

So for clarity, they don't wear pads faster than steel correct? You just need to be deligent about the pads. Like you would for DE's normally but being sure to not let them get way down.Are there pads that are better for them(PCCB)?

paver

Pagid has a relatively new pad called the RSC 1. It's for ceramics, although I haven't used them. Maybe somebody on the forum has and can chime in.

CRex

The problem with PCCBs is the choice of OEM pads. If you track, go with RSC1s or RS-29s. They'll keep your rotors in good nick--just as long as cast irons if not longer.

I certainly won't shy away from a car with ceramics unless you intend to use it on track 100% of the time. And FWIW I'll be getting my next car with PCCBs.
