Just ordered the Powerstop setup (fronts and rears) for my GS from Amazon. $144 out the door. $12 tax, free shipping. Will be here Wednesday. Boom. No knock on the Carbotech stuff, but dang, that's expensive.

"When these wear out" could be a very long time.... you might be better off pulling them while they are still relatively new and selling them on the forum. I'm sure you'll sell them quickly. Then move to whatever your second choice was.
I used powerstops on my Z51. I could tell they were not as good as OEM, and I was one of the ones that the pads made my rotors turn brown. I did not like that at all. I plan to do Carbotech on my GS soon.

I have had Corvettes for many years C2-3-5-6 &7 but I have never seen as much brake dust as I have on my new 2018 GS. I realize it is a by-product of the amazing brakes on this car, but does it get better with time or should I consider new pads? Cleaning the wheels is not a big issue but the silver barrels look dark grey in 150 miles. I have heard that ceramics lessen the problem but I have also heard that a by-product of ceramics can be squeaking at times. TY for any input.

I wash my car when dirty.... brake dust never bothers me because I'm too busy taking trips in my car(s) [C7 and Ferrari] to worry about the dust..... 70K miles on the C7 - 700K total miles in Vettes and 40K on Ferrari....
5,000 mile trip on Stingray coming up in two weeks!

I put Carbotech pads on both my C6 Z51 coupe and C7 Grand Sport coupe this spring. Hard to notice any brake dust and cars and wheels have not been washed since pads were installed. I feel that Carbotech are worth the additional cost.

I put the power stop Z26 pads in and I seriously regret it. Braking power and bite sucks compared to OEM. It was actually kind of dangerous- not because the braking system is inadequate but because I wasn't used to it. It was a big enough change from street to race pads for the track but this is going to make it far more pronounced. Not sure I'd do it again if I had the chance.

Put PS Z26 pads on my GS about 17 months ago with no regrets--no brown rotors, much-reduced dust on wheels, no noise, no performance degradation in street use.

I installed Power Stop Z26's on our '17 GS 18 months ago...... ZERO squeaking, never. Next to no dusting. No brown rotors as some have mentioned. Can't tell any difference in braking performance either. VERY happy customer.
Paid $120 on Amazon. While I would have liked to support a vendor here, Adam with his Carbotech brakes, I just could NOT justify the difference in costs..... $120 VS $450.

With all the complaints about the dust, and with better technology out there, you would think that an improvement would have been introduced early on. It’s a little frustrating to be planning on replaceing pads on a brand new car, especially at the high price point. So I’ll drive, evaluate, and make a change if necessary.

If I may hop in here and ask...
This problem is specific to the GS? I thought I read somewhere that the Stingray also had a brake dusts problem (or is that only if it is fitted with the Z51 upgrade?).

I wash my car every few weeks anyway. Doing the rims is no biggie.

As far as I know, the Z51 equipped cars use a different pad than the non -Z51 cars, and they create more dust. My 08 did not have the Z51 package and brake dust was never a problem.

When I bought my Grand Sport knew I would replace the pads as soon as I got the car home. I did with Chinese Power Stops since many folks said they were fine and only $118 delivered plus SC sales tax. They were low dust BUT I have a somewhat unique requirement of needing excellent stopping power with cold pads soon after I leeve my house, The Power Stop pads took more force and the confidence of stopping was not good. It's particualry an issue when there is a car on the rural road I turn on that is waiting to enter the 4 lane highway as there is little room for me to turn. After merging in ~65 mph traffic I don't want the cars to have to apply the brakes as I slow to turn so use the Vette brakes aggressively (see pic below.) Gave the Power Stop pads 900 miles to see if they got better. They did not so bought the Carbotech 1521s I should have in the first place. As experienced for 3 years with my 2014 Z51 they stop great with cold pads! Very linear pedal modulation and predictable stopping. Also fine when warm/hot and very low dust as were the Chinese pads.
Here is another forum post I copied describing the same issue:
Z06NJCF Senior Member, "Initially you will feel that you have to step harder to make them brake the same as OEM. That's because all you know up to that time are the OEM brakes. However, with time, it becomes like muscle memory. Now I just brake like normal and don't even think about it.But I'll never forget the 1st day I got them installed and I was driving home, I was like "WTF's going on here...I'm gonna end up rear ending somebody"
PIC shows what I do every time I leave my home. With cold pads I stop very aggressively to avoid the 65+ mph traffic that I merge into (60 mph speed limit) having to slow significantly as I make that turn. Often a number of trucks in that right lane including 18 wheeler log trucks going to the paper mill!

NOT a great idea as more work when you change as you'll need to get the rotors clean of the OEM brake pad residual.

With my 2014 Z51 I did wait 6 months living with the dust, 6 months too long! I was cleaning my wheels every 100 to 200 miles NOT just because they looked bad BUT the dust was pitting my black wheels! When I got my Grand Sport there was no question change as soon as I got it home and no need to remove the brake pad residual that will be on the rotors after the 500 mile break-in. Your car your choice! It's an easy DIY to change. This is a PDF of my issues and installs: http://netwelding.com/Ceramic_Pads.pdf
