I used them for 15k miles and it was pretty consistent. I don't care if others use powerstop, doesn't bother me, I just share my experience with them is all. I think I probably got a set that were defective, old or something. They made my rotors brown, they didn't work as well as stock, and during paced laps at NCM Motorsport Park, they did not work well after 12 minutes of light to moderate 'track' time, if you can even call it that since we were behind the pace car. They are certainly not suited for hard driving on track or street in my opinion, but I also think the carbotech 1521 are not for track either. They are both intended for street use only from what I recall.
Side Bar-Quality Control:
The issue with quality control IMO is what might cause excess iron, which probably caused the brown stain on the rotors. I'll repeat the possible issue briefly.
When I managed a welding materials R&D Lab and we used sand and bauxite to make welding fluxes. The open pit mine where the sand came from was very interesting. I passed it often on my way to the 1/4 miles drag strip in Thompson Ohio. There were areas with pure white sand and most with the brown sand used for concrete etc. That brown is caused by iron impurities. Mother Nature does not make pure ores! We paid about 3 times the price as I recall for a chemically checked product with guaranteed low "tramp element" levels, like iron. I also recall that company had an even "cleaner product spec" they sold to silicon chip manufacturers who refined it further. It was even more expensive.
I also recall we bought bauxite, and ore that has a high amount of aluminum oxide. It's what is used to make aluminum. We use it in welding fluxes. Just like the sand example, it comes with impurities and Iron compounds are some. We paid over twice the price for bauxite from Australia than we could have from China becasueof the variability in Chinese bauxite.
Yep the rotor color could well be a batch issue. Not only did we specify and get a chemical analysis from the supplier, the flux manufacturing plant was required to chemically check each batch purchased to see that it met our specification! That is NOT cheap! But that is required to make quality, consistent products.
From the high pad temp published by PowerStop, IMO the cold pad performance is inherent in that product- using there own data. I did this research to try an understand why I was tossing $125 pads (with sales tax) out and replacing them with Carbotech 1521 pads I knew worked on my 2014 Z51. I didn't toss the PowerStop pads because I like changing brake pads! I paid for both sets! Fortunately the PowerStop pads were so cheap it really didn't bother me to toss them to get the cold pad perforce I need in my somewhat unique situation. After all it's a >$60,000 car
Just Sayn'!

An interesting test for those who have not installed their power stops would be to put them on the front only and drive for a while, then compare to the rear rotors and see if there is any discoloration.

It's also occurred to me that those who reported performance issues might've had some pad grease leach out onto the rotor. That likely would've worked its way out in time, but if they became disenchanted and changed to another brand soon thereafter it might've been construed as poorly performing pads. Just a thought.
It does seem odd how the same guys keep championing the pads that cost 4x as much and over exaggerate how bad power stops supposedly are. Maybe several years ago power stops had quality issues and they got bad pads, or maybe there are other reasons these guys keep slamming them, but I'll say again - Ive had zero problems with mine - no browning of the rotors and no noticeable difference in stopping power. And I've used power stops on other vehicles over the years and had no problems.
I get the whole corvette tax thing, but why pay 4x as much for pads that in no way, shape or form offer 4x the performance?

Performance isn't linear with cost either.
LMFAO at using Power Stop pads like a real track/race pad.

LOL@ driving street pads "not hard enough" on the street. Come on dude. 1500 degrees? Maybe in the mountains somewhere I guess? Mexico?
Sounds like you need track pads for the street, if you drive that hard. Stick with the oem's

Burning Brakes
I have PowerStops for daily driving. Virtually zero dust, it's wonderful. The initial bite is definitely not as strong as the OEM Brembo's and definitely not recommended for the track. When I do a track day, I throw the Brembo's back on. Next time, PowerStops go back in. $100 for pads that give off no brake dust and still stop well is fine. I had 1521's and I felt the dust was not much improved. But anyone thinking they can run the regular PowerStops at the track must be on crack. No such thing as no brake dust/race/track pad.

That's not it (and I didn't use any grease)
I got my pads 2 months ago. The guys who think they didn't lose any performance aren't the guys driving their cars hard.
Performance isn't linear with cost either.

But again, me and a bunch of other people are saying right now, the power stops are not browning rotors. And if someone wants to test their stopping power vs competing brands that cost 4x as much, I'm willing to bet big that the difference is minimal, if any.

You're missing the point. I'm not saying you see 1500 on the street. I'm saying that figure is bullshit and there is nothing to derive from it. I wouldn't want OEM pads at 1500 degrees either.

Powerstop Track Day Pads
Why not use the Powerstop Track Day Pads on the Track??

Mostly the fear of death, but damaging my car too. I don't want a low dust track pad. I want one that will maintain a predictable coefficient of friction from lap 1 to lap 15.
They don't make them for the C7 anyway, unless I'm mistaken.

Using Powerstop Z-26 No Browning
I have Powerstop Z-26 pads and DBA 4000 rotors on my 2016 Stingray with no browning and very low dust.
I have run the Powerstop Trackday pads on the track with no browning, no fading.

Powerstop Trackday pads exist & create dust but not bad
Powerstop Trackday pads create dust but its not too bad. Have even left them on car between back to back weekend events.

Lol what? Because I can notice the difference between shitty low dust Chinese pads and a good set of brembo pads, I shouldn't drive on the streets?

I disagree. There is very noticeable difference in braking power. You have to push the brake much harder and maintain pressure longer. Pedal feel is complete crap. Only with the trade off because I have light colored wheels. If I had black or any of the metal colors (brushed, unpainted, pearl, etc) I wouldn't swap.

It's amazing that you are still alive, because with the way some are talking about the power stops, they're such a downgrade that you're almost guaranteed to end up inside a tree...
