PCCB's would be nice. (for all my street use and rust free winter storage)

but i would most certainly swap the carbons for iron rotors with for all my track use.

i currently run all my old irons for the street and keep my fresh rotors for track. works great $$.
PCCB's would be nice as my street set up as opposed to old DE irons, but it is not really a concern.

JIm, I hammered my PCCB's around the nordschleife for 4 days solid with no complaints ... although now that the new cars have the larger 380 fronts and the new l/w hat design it's probably a closer call than before ... I'd still opt
for the PCCB's ...

p.s
I am SUPER jealous ... I just want new # but cant find a build slot!

The PCCB debate just never gets old.

thanks larry. i was all set on just getting the iron disks and now i'm wavering again! also i'm starting to like the stereo delete which is free versus getting PCM/fat stereo/bluetooth/iphone for $5K of useless dead weight!

Larry Cable

definitely skip the PCM nonsense ... no stereo??? .... wow!

will be at the ring 8/1-4 probably renting unless I can get a build slot!

I too was torn between PCCB and steel and subsequently went with steel. Spoke with many folks at the track and several trusted Porsche Mechanics. Bottom line, the PCCBs were marginally better than the prvious steel and maybe no different then the new steel in braking. They will last longer but you WILL have to replace them if you track the car and the cost is goofy. Could run as high as $14,000 for pads and rotors. No thanks. If you are only on the street I would do it without a second thought, but even the remote chance of having to replace them after the track is frightening at that cost. Steel are fine with me.

What's involved in switching from PCCB's to OEM steel rotors and pads for the 2010 GT3(not RS). Just simple substitution of rotors and pads keeping the yellow calipers?

roberga

according to Porsche the delta between irons and PCCB is 10lb a corner.

Larry Cable

this has been discussed elsewhere, but it is not possible to simply switch the
rotors and pads etc from PCCB to iron.

P.J.S.

really?

what else needs to be done?

Brembo advertises an iron rotor alternative, type III I believe, for PCCB equipped 997.1 RS... which I took to mean that it is in fact possible to just switch out the rotors...

edjumicate me

Larry Cable

Sorry ... I was being "imprecise" in my interepretion and response...

more correctly what I meant to say was:

"I believe cannot directly subsititute Porsche OEM iron rotors/pads to replace PPCBs due to differing dimensions, including diameter, thickness, hat-offset"

(I would add the caveat that this applies to 997.1 I dont know about the .2's)

there are a (surprisingly) small number of aftermarket alternatives (e.g Brembo)
which offer a custom rotor/hat solution which is a direct replacement for the
OEM PCCBs.

one note of caution with these: make *sure* that the rear replacements (hats)
will work with the OEM e/parking brake.

Some of them do not, and the only solution is to remove the OEM hat from the
rear PCCB and install an aftermarket rotor on it in order to allow the ebrake
to continue to function ...

edjumication complete ...

P.J.S.

Gotcha -- thank you
makes sense

In summary -- no OEM/Porsche options that is direct bolt on

I know mikymiu did it with cup rotors on a .1 RS but they required "modification"

Larry Cable

Yup - sorry I should have been a bit more precise in the 1st place.

The intriguing question (which I do not have an answer to) is about the .2 rotors,
in particular the fronts ...

I wonder now that they have moved to a 380mm front and repositioned the caliper if in fact these rotors are now interchangable with the PCCB setup ...

that might be a much cheaper solution than aftermarket.

But I think you'd need access to at least PET and perhaps be a "shop" in order to answer that question!!!

With the '10 steel rotors the same diameter as the PCCB, I see little incentive to spend the extra coin. I always thought the 7's 19" wheels dwarfed the 350mm rotors. Both steel & ceramic obviously perform...

Larry Cable

I tend to agree ... although I still think the thermal and (minor) weight advantage are probably still worth it (until the time when it comes to replace the rotors)!



ideally if the .2 irons were a dropin I'd still get the PCCB's then exchange them for irons and put the rotors "under the matress" ... just in case!
