ipse dixit

There's no other Porsche approved method to test the PCCBs.

What other method would you suggest?

Masonbrick

I understand the skepticism regarding the Porsche testing method, but I was never comfortable with the PCCB's while driving the car. The brittleness and cost of replacement had me looking for a steel conversion before I'd even bought it. The brake feel also made me a little apprehensive. The conversion now makes my turbo's brakes feel more familiar to me. And I love these pads. I had them on another vehicle and I determined that I'd put up with the cost for them because they were actually worth it....I don't know what my other choice would be, maybe Endless ME20s or stock GT3 pads?
Also, I forgot that one potential reason for my difficulties, and don't laugh too hard, is that I forgot my regular driving shoes and had on my Rod Lavers which probably didn't help my cause too much...

I happen to love my PCCBs but I don't really track my car. But when they go there's no way I'm spending 25,000 bucks for new ones. Not for brakes. Their are much better things in life to spend that much money on. They will be replaced with Girodiscs when that day comes. I don't ever imagine selling the car so it really doesn't matter to me what brakes I have on in terms of resale value.

Ditto. I love the way my TTS breaks with PCCBs -- zero complaints here. But, I do not track my car. If my PCCBs failed, I'd probably replace with something cheaper and live with it ($25K to restore function seems.... well, unnecessary). I don't sell my cars, so like sdg1871, I don't really care about resale value.

We do carry the line of Giro rotors and pads of any compound - PFC or Pagid - RSC1 / RS29 etc

I'm thinking you use the same method as for steel. Look for blemishes or failure/delamination. The Carboteq seems to be very, very conservative and designed to sell new rotors when the rotors are down to maybe half life, like other Porsche "maintenance guidelines" seem to be.

My dealer has NEVER replaced a PCCB rotor due to wear, and there are a lot of track guys here near VIR.

I have 1 1/2 trackdays, 1/2 due screw in tire, on my Girodisc, they work great.

Choice, drilled or not on the Girodisc rotors?

Do you have to get new calipers or can you just replace the PCCB pads with steel ones and swap out the rotors?

Randyc151

The big seller for Girodisk is that it's a direct swap for the PCCB rotors. Just swap rotors, install pads for steel in the existing calipers, and go crush everyone. Simple as that.

I like easy. Thanks Randy!

lol i have a gl63 as well.
the weight **** up the brake so hard

We're on our third GL and they go through brakes fast. The weight is a big culprit but the stability control is the bigger culprit and eat up the rear inside pads faster than the other pads. I just replaced the rear brakes at 22,000 miles. The front pads probably have another 5-7k miles left. This will be our last GL since we no longer need a 7 seater. Good excuse to perhaps to look for a Cayenne S.

My car is at 15,000 miles. I drove like I stole it almost everyday.
It turns like a grandma, the power feels good.
With only 4 members in the family, i felt stupid to get the gl63.(already had a cayenne)

One more question...How would you rate the fading (if any) with this setup vs. PCCBs when driven hard, i.e.. on the track?
You've got the GL63, which is a monster of SUV so I'd drive it like I stole it too if we had one. We have a GL450, which is my wife's DD and used for her soccer mom duties. I think she's ready for something a little more nimble.
