I'm at about 50% wear and planning on changing brake pads soon. I'd like to upgrade the pads, since I hope to do a couple of track days this summer, but I want to keep my PCCBs on the car for now (if I end up doing a lot of track days, I may switch to iron rotors). I'm going to try to keep temperatures under control by also switching to the cup ducts, and Castol SRF (and of course do cool down laps). And I'll try to avoid ABS, which is also suspected in excessive PCCB wear.

Anyway, hearing that others have had problems with the stock pads not handling high temps well and deteriorating at the track, I've done some research on the site regarding good alternative pads for Gen1 PCCBs. I'm looking for something that is tolerant of high temps, but isn't going to be too aggressive for the PCCBs. I don't want to eat up the rotors. Is the consensus that Pagid RS19s are the best street/track pad for Gen1 PCCBs? It seems that a few folks here with PCCBs have run the RS19s and found them significantly more effective than stock, and still pretty easy on the rotors. Any additional thoughts or confirmation? What's the best pad out there that strikes this balance?

Thanks in advance,

Richard

Porsche (Greens) is the track pads. The front is P-50 material the rears are P-40 which is the same as the black but thicker. Sunset Imports in Beaverton Or can get them and the price is tough to beat.

Thanks Roberga. I appreciate the input, but I've read a number of Rennlisters comment that the P50 (green) pad is a very aggressive compound for the Gen1 PCCBs, and was suspected of contributing to some of the early track failures (perhaps coupled with lots of ABS use).

Did you use P50s on your Gen1 rotors before you switched to Gen2, and if so for how long?

Cheers.

I use them on the rear PCCB with no problems...the fronts are the AP racing rotor.

P50 is the track pad for pccb

RS 19 work very well on GEN 1 PCCB. For some reason they are not approved for Gen II rotors.

Richard, I have a set of rear black pads for PCCB sitting around. They have two track days on them. Let me know if you're interested in buying them.

Richard, I only use black on GEN I. I looked at going with something other than the greens but a solid local distributor of after market pads advised me to stay with the Porsche part as they are matched for PCCB. Do not know but they work for me.

I ran two sets of greens before switching out to steels. I actually like the blacks much more. The feel was a lot better. The greens just didn't do it for me. I'm now running performance friction pads 97s/01s f/r with cup rotors and love the setup.

I use the factory P90 compound for those times I run my gen 1 PCCB on the track (usually I run the iron Cup rotors). According to Joel from PCA, the P90 compound is equivalent to the RS19, with a very slight alteration in the compound for ABS issues. But the P90 is pretty much equivalent to the RS19 and the P40 is pretty much equivalent to the RS14 (according to Joel).

Thanks very much for all the input so far. This is very helpful. A few follow up questions:

1. Which pads, exactly, do the yellow and black colors refer to? I know green is the P50 compound. I've read that the stock pads are called yellow, even though they are no longer actually yellow. I recalled reading that the yellows were now actually black. But it's not clear to me whether people are referring to the same pad or a different one when they reference black. Could someone please tie the yellow and black pads to specific current compounds (using either the Pagid# or the Porsche P#)?

2. AllanJ, your info is particularly interesting because this is the first I've heard that Porsche reformulated a pad to deal with Gen1 PCCB ABS issues. If the P90 is very similar to the well-regarded RS19, but modified slightly to work better with ABS on the PCCBs, the it sounds perfect. Is anyone else using it? When did it come out and what applications does Porsche now recommend it for? I'm surprised that Pagid didn't mention this pad when I called them with the questions I've raised here.

Thanks again for the great info guys.

The part number for the blacks is:
980 351 939 00 Front
996 352 947 03 Rear
Expect to pay around $350 Front and $320.00 Rear.

The part number for the greens is:
996 351 940 92 Front
996 352 930 90 Rear
I can't remember what I paid.

Hi Richard,

I got the info on the pca.org website. Go to the Tech Q&A section and you'll see Joel's name. Check out those posts and search for PCCB info. Here's where I go the info about the pad compound composition.

Another thought: In these early posts by Joel about PCCB issues, he never mentioned the P50 (green) compound. Maybe it wasn't available then? Not sure. I have to sign off for a bit so you might want to have a look through the other posts on pca.org and see what Joel says.

Black is P-40 compound. The issue I had with them tracking was getting big cracks even with >50%. They got too hot. The greens being P-50 take more heat. They do work differently than blake on the road. Porsche states that the greens are for track use only.
