I searched through the forum and found bits and pieces of data on the brake pads etc. I thought I would put the data all in one place to be easy on future searchers. Here goes:

OEM Brake pads are supplied by AC Delco. The pads themselves are made in Italy by Ferodo for Brembo. When you buy the pads, the box says "AC Delco", "Brembo" and "Ferodo". The pads say "Brembo" on the back side.

The rotors, are they the 2 piece design, or the original 1 piece with the clicking problem ?

That is the original rotor part number. I don't know the new two-piece rotor part number.

Does AC Delco supply the original Brembo pads or are the original equipment pads not even Brembo>

I bought the AC Delco pads from Rock Auto. The box is labeled AC Delco. The pads are labeled "Brembo" by Ferodo.

AC Delco is listed as the OES (Original Equipment Supplier). It appears that AC Delco supplies Brembo pads to Cadillac.

Bumping an old thread, as this seemed a reasonable place to post this.

I just ordered some ACDelco pads from Rock Auto, part #17D1405M (Durastop Professional semi-metallics). The box also lists them as GM #19288002. GM Parts Direct shows them for ~$40 (list $76), while Rock Auto had them for ~$49. Obviously that's a different part number from the OEM part number (25940447) that Low_ET listed in the original post, and they're also a heckuva lot cheaper. I'm curious to see how they do for daily driver duty. (I'm also curious how many V2 owners have ever been offered this pad option rather than the more expensive stock pads. Having not actually installed and tested them, my hunch is that these are perfectly capable of handling the driving that most V2 owners do day-to-day.)

Interestingly enough, I discovered the '12+ Grand Cherokee SRT8 uses a variant of the same caliper as the V2. The caliper looks a little different, but uses the same FMSI D1405 pad shape. I've done some searching around and the OEM part number is 68144427AA. My searching turned up wildly varied pricing, from $172 @ factorychryslerparts.com to $317 at factorymoparparts.com and jeep-wholesale.com. I called the local dealer to confirm the part number and check pricing - he initially said the part number wasn't coming up as that, but then told me it was correct, and list price is $460 (very similar to the $450 list price of the 25940447 CTS-V pads). Based on that list price I'm guessing the $317 pricing that most sites show is correct, and that factorychryslerparts.com probably has them listed wrong. (Might be an opportunity to get some OEM pads for a huge discount.) And of course I know nothing about the Jeep parts - are they made by Ferodo for Brembo, like the V pads, or are they made by someone else? If they are made by Ferodo, are they the same compound as the V pads? I'm not inclined to spend the couple/few hundred bucks to find out, but maybe someone else will. :)

I went with the Wagner Perfect Stop, SEMI-METALLIC, and love them for tracks and daily use since they leave very little dirt. No longer do I have to change pads for the track. Maybe $60-ish for the fronts and $30-ish for the rears?

These sound great!
Are they quiet?
How hard have you used them on the track? Any fade? I love how the stock pads held up for me on the track and with multiple 160-0 stops.
Any idea of how they wear compared to stock?

I've had the lower priced AC Delco pads on the car for a couple weeks now and I'm very happy with them. No noise at all, but they're way better than the Hawk HPS pads in both initial bite and overall stopping power. The only thing I can't comment on is how much dust they generate; my winter wheels are "hyperblack" Rotas, so they hide dust quite well.

Your laps will probably improve mightily if you don't come to a complete stop on track. You'll avoid pissing off the people out on track with you, too! :p

If you like the stockers on the track, you should try some track pads. They can put you through the windshield if you are not careful :)

They are better than stock, since they are so clean. I leave them on all summer, and change to ceramics for the winter when I put my snows on. They have NO problem stopping from 140 down at Road America either. Where are you that they have a mile? straight where you can hit 160? I've never gotten any fade, noise, or nothing other than great stopping.

This is a timely post since I need new brake pads soon. I've not had good luck with aftermarket pads (on my C4 or C5)- they usually end up with poor bite and a soft pedal. However, the $450 list price for front pads (or $290 for GMPD) is a huge incentive to look at aftermarket. Any suggestions?
My C5 now runs stock Z06 pads and EBC Yellows on the track.

Hmmm… I wonder if that had anything to do with that big pileup behind me??

But seriously, folks… a group of guys I go on drives with rents out an abandoned runway 1-2x/year outside of Stockton, CA. I have videos taken by my passenger of me running in my V against an M5 and a C6. If anyone's interested, I can post them somewhere (YouTube?).

They are both from the OEM supplier, AC Delco. I doubt they are equivalent for high performance use. I have only used the more expensive AC Delco/Brembo pads so far.

The cheaper ones may work just fine on the street. I wouldn't risk it on the track. I use up most of my brake pads on the track.

That's what I figured. The cheaper ones are probably ACDelco's own sourced OEM pads whereas I think the standard ones are Brembo. I am curious about the performance difference though. Sounded like someone earlier bought them and didn't think they were too bad.

I've never run the OEM pads, so I can't compare directly; there's no way I would pay $250 for street pads. The 17D1405M pads are great for street use, and the price is right. They are pretty dusty, but I've used pads that were worse. I've run a variety of "performance street" pads over the years - Carbotech, Hawk, Mintex, Porterfield - on 3 different cars, and these cheap ACDelco pads perform well enough that I don't plan to ever spend that sort of money again.

I think that the Raybestos Professional Grade metallics are the same thing as the ACDelco Professional Durastop semi-metallics; check rockauto.com to compare pricing.

Brake usage varies a lot, both depending on the track and depending on the driver. Personally, I always run track-specific pads at track events (along with cooling ducts), and think I would kill street pads in short order. But there are others who have run street pads on track without issue. As always, YMMV.

Anyone use the PowerStop Z26 or PST pads? Z26 being an "extreme performance" carbon fiber+ceramic hybrid street pad, and PST (PowerStop TrackDay) being a carbon fiber+metallic hybrid track pad.

Pricing on them are really good- about $140 shipped for the Z26, and $250 shipped for PST. This is front and rear. I may try the Z26.

This thread is timely and interesting to me. I replaced the pads on my V Coupe with cheap aftermarket pads from the local parts store, both front and rear combined came to about $130, however, the pads are useless! I was coaching at Laguna Seca and was asked to do demo rides, after 7 laps, the front pads had about 2mm remaining (from new!), I hadn't planned on tracking the car that day, but didn't think it would be as bad as it was. The bite was also lacking.

So, the question is, what pads, for a decent price, does the forum members recommend for some track use, and some street use? I really don't care about noise and dust is a nuisance but I can deal with it. I don't want to change pads for the track and sometimes appreciate pads/brakes that bite well on the street when aggressive. Part numbers/make and price would be appreciated. Also, I have the 2 piece rotors, anyone have a source for them that won't break the bank? I was looking for ring replacement kits with no joy.

Any advice would be appreciated!

Not to bust your balls, but if you're "coaching & instructing", and giving demo rides, you should surely know generic pads won't last more than 3 laps. They will disintegrate. No over the counter pad is going to last on a heavy V. I'd have more faith in the factory pad... which is marginal on track.

Hawk DTC-30s. End of story. They are not cheap but I found them to be fan-flippin-tastic for autocross, track and street, combined. They bite well whether it's cold, wet or normal.

Thanks for the tip thebigjimsho, I have not tried Hawk's on my other cars before. Been running the Porterfield 99 compound on the Vette (discontinued compound, bought 5 sets at close out when they were discounted about 75%) and also a Raybestos race pad I was talked into at LPI for the Vette.

Still trying to find a source, other than GM, for the 2 piece rotors. Mine are fine, for now, but I like to have a source at hand.

To respond to the ball busting from the blur, there were factors associated with my decision to go with cheap after market pads, most importantly, the car was on a lease and I was torn between turning it back in and keeping it, so didn't want to spend anymore than I had to prior to the lease return. Turns out, I bought the car out because I just like it as a daily driver too much. I have only tracked the V twice now, first time was coaching my wife on the stock pads when the car was new and then the demo rides. I would have thought that at 7/10s for a few demo laps even cheap pads would hold up, but I learned that they don't! If I were to track this car, instead of the Vette (which is set up for the track with all the goodies), or one of the race cars (have 3 Lemons cars within our team), I would add a diff cooler, spindle ducts and try the Hawk pads at a minimum since I saw a diff over temp after the 7 laps as well. Of course, all my cars get a brake fluid flush and change annually with Motul.

Of course, any other recommendations for track readiness of the V would be appreciated!

The DTC-30 I've heard are a pseudo replacement for the Hawk Blues that were always very popular.

I always used Motul fluid with my Hawk pads. That'll last you a long time wherever you run. That stupid diff temp warning, however, is a pain...

You can get the OEM rotors (with ACDelco part numbers - 177-1145/1146) on Amazon. Right now they're close to $300 each, but the price moves up and down. I picked up one pair for just a bit over $400. Even at $600 for the pair, that's a helluva lot better than dealer pricing, and they're Prime, so free 2-day shipping.
