My advice for the Gen I crowd... change your pads often if your hitting the track. I couldn't believe how roasted my pads were after one DE day. Keep the pads over 50% to help with the heat and try not to hammer the rotors with the ABS. PAG didn't recalibrate the ABS for the PCCB equiped cars.

If you gotta swap the Gen1 for steel, cup rotors are the way to go. You can use the 350mm front rotors from the 996 GT3 (street or cup). For the rear you have to use the 350mm rear rotors from the 997 GT3.

 

Ive been doing a search for a very long time now and still cant decide, so please help me if you have used your car on track

My car is the MK1 GT3, My current options are:

1)Keep the rotors and change Pads to

Pagid
PF97s

and use DOT 5 or 6 Fluid

2)Change the rotors to CUP rotors

All Around 330x34mm

3)Change the rotors to MK2 rotors

Front Rotor (350 mm x 33 mm)
Rear Rotor (330 mm x 28 mm)


4)Change to Brembo-Sport System GT (6-piston)

Front 380x32mm, drilled discs

Input?

 

I'd change to MKII specs but, if I remember right, the calipers are different being 6 piston as opposed to the 4 piston setup on the MKI GT3. I'll also check some UK forums because they have much more experience with the MKI GT3.

 

I run second Gen discs and green Porsche Motorsport pads with good results.

 

I think you guys are absolutley right!

I figured that what I need simply is a 6 piston brake kit with steel lines, racing pads and an excellent brake fluid

at least for now!

I have a track day tomorrow, im starting with stock 4 pot but using Pagid yellow, hope it goes well until i upgrade

thanks guys for taking the time

 

I've heard there's Gen III as well. So for whatever reason the Gen IIs were flawed as well.

 

we've had a few failures, early on, with the PCCB rotors on cars that were tracked. Keeping pads "thick" helps....using "green" factory motorsports pads help...sooner or later you will need to replace them...thats a fact if your a aggressive track driver doing DE's. If your not now...you will be:-)
Simply store your stupidly expensive Pccb's and install cast iron all around. When (if) you sell, and you will :-) you have a beautiful set of Pccb's to put back on. I don't see the debate here. The marginal difference in braking, or more appropriately, lap times....gets eatin' up real fast when you receive the "tab" for a replacement set of these "pergatory" parts.
We service so many Porsche's equipted with gen 1 AND gen 2's .... and this is really a simple thing to do for wallet protection.havefuntakechanceschangerotors-Mark
BTW- Even better is to put on "real" floating rotors-a bit noisy but better for the track. Porsche rotors really don't float much (not at all)

 

I have a 2009 Carrera S with PCCBs. My car has 33,920 miles. Since February of 2009 it has had at least 2 track days per month. Today I replaced just the front (stock) pads. The rears still have life in them. All 4 rotors look new.

I have a friend with an '07 GT3 with around 30,000 miles. He just replaced pads front and rear. His car has roughly the same number of track events. Rotors still in excellent shape.

I think the best advice I've heard is to replace pads with 50% life remaining.

Happy Motoring

 

Are you saying you've only changed pads once in 30k miles? Even after tracking 2-time per month? What sort of track do you run, oval?

 

Ouch Laguna Dude...almost sounds like you're trying to make fun of me.

...just wanted to provide 2 examples of actual PCCB ownership experience that might help another member make an informed decision. My home track is Texas World Speedway (15 turn/2.9 miles)

...Happy Motoring

 

my previous posting must have the following addition.........NOW, THE factory (motorsports) no longer offer the "green" pad for DE users. there is only one choice for that particular rotor from Porsche for pad material. Given the expense of changing rotors due to poor choice in pads, dictates a clear decision to use only OEM stock pads.

 

I run third set of pads on my 997 tt -15k mil

 

So there are no "Track pads" for the PCCB now? How can that be?
Many have posted the pads/rotors get eaten up realy fast with the street PCCB pads on the track.

 

The only pads recommended by Porsche are the OEMs. The rotors wear just fine. There is nothing unusual about the PCCB set-up other than reduced unsprung weight and cost.

 

Not at all. Just asking a legit question...as it seemed a bit long between pads. the oval comment was simply to add some spice to dialogue. In no way was I trying to discredit your post or info provided. Just seemed odd to track frequently and not change pads for over 28K miles. From my experience with PCCBs, changing pads more frequently is a good thing..as you stated. TC off is also a good thing.
