There have been at least a couple of threads here where the topic of pad options that included mention of what is offered by CarboTech. I reached out to CT, and wanted to pass along some information that may be useful in some way.
I've posted similar information on the SS Forum and will post on the PPV (New Caprice) Forum. I've edited some information to fit maximum post length limits here.

I'm not here to serve as a clearing house, so in regards to any additional specific questions I must defer and suggest direct contact with the company--I found them quite responsive and receptive to my inquiries.
Please note: I am not endorsing nor have I ever used any CarboTech products, to be clear.
This series of exchanges all took place between May 10 (Friday) when I submitted my original e-mail, and the rest of the responses were on May 13.
Subject: several questions
Wanted to confirm cost for the 1521 spec pads for CT1351 FMSI/caliper fitment as used on 2008 Pontiac G8. Some comments I've read suggest they cost $300+....ouch!!!
Also, the lookup for Brembo pads (CT1001 & CT1001A) suggests there's a different spec for Cadillac CTS-V (2004-2007) and Pontiac G8 GXP (2009). OEM pads are listed as the same, rotors are the same thickness, but the CT listing indicates that CT1001A is about 0.040" thicker (pad material or pad plate?). What is correct for each application?
The CT1351-1521 retail for $208. We do offer club and forum discounts if you buy directly from us.
We would have to make these, 2-3 days to have them ready to ship.
My listings show the same 4 pot Brembo, the CT1001 for both the CTS-V (2004 edition, the newer CTS-V has a 6 piston caliper) and the GXP. If you're looking for the 1521 in that pad shape, they retail for $170 and are in stock.
Do you need any rear pads?
Subject: Re: several questions
Mike, thanks so much for the reply--my objective was to enlighten some folks on the G8 Forum--they were citing pad costs (for 1351-1521) of over $300. Knowledge is power, so this might get some owners to re-think their buying decisions and give CT a try.
In addition to the G8, the common platform communities (which I frequent and post responses to brake questions) that might be inclined to give CT pads a try include:
11-17 Chevy Caprice PPV - D1404 and D1352
14-17 Chevy SS - D1001 (officially D1474A, which is a newer variant that CT does not offer) and either D1352 (PBR) or D1053 (Brembo) rear
NOTE: I assume CT does not consider any need to provide a D1474 pad (with dampers), but COULD make them with customer-supplied cores
The question about Brembo was to look at clarifying info I found posted in the CT website, and to let everyone know what it does cost to use your products, which are very popular with the auto-x/track day crowd. Brembo upgrades are common & popular on the Zeta sedans (G8 & Caprice PPV), and pad options are always evolving, so I wanted to be sure the CT info was accurate.
I'll monitor the Forums and make clear that the CarboTech option is not as costly, for the ROI, as many may assume. I may have to try some myself!
That's great and greatly appreciated. The forums do often times have a lot of bad or wrong information. There are also "dealers" who buy from our WD's and mark things up significantly and that pricing gets out there but isn't retail. Please also inform them that the website does have a way to see retail pricing so people will know if they are getting price gauged by someone.
That 4 pot Brembo, the CT1001, is one of the most popular pad shapes we sell. The C7 Stingray and then Z51 packages put us behind the 8 ball throughout 2014 and 2015 when they started using it. We could not keep them in stock on our 1521 compound. It was already on the earlier version of the CTS-V, Camaro SS as you stated, Ford put it on some of their Mustangs and it had already been on the Mitsubishi EVO and Subaru WRX STi. The C7 just put it over the top. We tend to keep 20-40 sets of those in 1521 on the shelves even today. We actually had several EVO, STi and CTS-V customers buying the kits or parts through Chevy because the Camaro version was cheaper than the others, which is funny, because they are all the same outside of the rotor size.
We also stock the 6 pot iron rotor version for them all (CTS-V, C7 and Camaro), the CT1405 front and CT1718 rear. Some of the Camaro's and the CTS-V use the CT1053 in the rear, which we also stock. If anyone with the Carbon Ceramic rotors would like a nice change for the street or track, our 1521 works great with those rotors and on the track the XP8, XP10 and XP12 are a great way to go too. CT1395 front and CXT1165ZR rear.
Thanks again and please let me know if we can help you with anything else, including ordering.

So it's "problem solved" for the folks that think the pad dampers are essential! Brembo & GM have worked very diligently to keep customers happy....the comment about differences in OEM pad prices, in the case of the Chevy SS, is that many parts or specs for that car, as well as G8 & Caprice PPV, originated in Australia, where those cars were built. So, even though Camaro Brembo pads (as in D1474) are fit/form/function compatible, somehow the GM purchasing process let the Australian-sourced OEM part numbers remain, and customers or dealers maintaining inventory were having to spend much more to offer/purchase the production service pads for that application.
All of the OEM Brembo pads for these vehicles (CTS-V, G8 GXP, Camaro SS, SS sedan and even the PPV D1404 pad) use Ferodo HP1000 friction material, which has it's own issues--which seem to be at least part of the reason for the pad damper "fix" that started in about 2009 with the Camaro. There have been multiple iterations of brake squeal bulletins issued by GM since the Chevy SS sedan first came along in 2014. The primary approach has been to slather on the Brembo-spec copper paste (a Dow/Moly product formulation) in a very strategic manner. Done correctly it seems to help suppress the squeal issue, but in most cases noise tends to return after a time, and many owners can't seem to accept that as the nature of higher-performance brakes. Some resort to ceramics, or something claiming to be noise free, then complain the brakes don't work as well as with the OE pads...well DUH!
Anyway, it's good to know that CT1474 is the small damper variant, for those that are worried about not running the dampers in a street-only situation. And I'll add that it's interesting to me that both the CTS-V and G8 GXP used D1001 pads, and I've not noted that there was an issue with brake squeal on either of these applications, with both using the same caliper & rotor as the SS sedan, which, unlike the earlier models (with no dampers) caused havoc for GM service. I can't figured what could have changed....a real curiosity.
The 345mm PPV rotor & Alpha Brembo caliper combination still uses the same pads--production is the D1474 pad which was never called out as fitment for G8 GXP, but the Alpha caliper "spec" is with D1474, even though D1001 will also fit the Alpha caliper.
The noise problem is due to the friction material. All of the shims, weights, pastes, etc....only do so much but never truly solve the problem. Same with the dust issues. They have actually done us a HUGE favor by running the pad compounds that they do. That is why our 1521 has sold so well to owners of these cars. We give them equal to when cold or better stopping power without the excessive dust and noise and without the loss in stopping power that ceramic brakes have problems with. Our carbon, ceramic and kevlar mixture is very different from what GM and others have used and it why our sales have been so solid. GM isn't the only one that has this problem, we have "solved" this for several owners of every manufacturer out there, some are just worse than others whether domestic or foreign.
Thanks for posting, we appreciate it.
