I recently replaced my stock brake pads with Porterfield R4-S Carbon ceramic pads and they are great.
I even cleaned the barrels of the wheels and they are still pretty clean after 2 weeks of around town driving.
The stock pads would have the front wheels pretty dark by then.
It took a few days for the pads to bed in, and in the beginning there was a noticeable difference in the "bite" of these pads.
I needed to use just a bit more pedal pressure to get the same braking, most noticeable when coming to a full stop.
Now, after a few weeks, the pads are bedded in nicely and I am used to a slight different pedal feel.
I am completely satisfied and glad to be rid of most of the black ugly dust.

Nice Ride

I wonder how much this will affect stopping distances and emergency braking...

Todd in PA

I don't think it will have any negative effect on stopping distances or emergency braking, both pretty much similar.
Maximum stopping distances usually mean engaging the ABS and these pads will certainly do that.
I have used many different types of pads as a driving instructor for Porsche Club, mostly on 911 variants.
Each had subtle differences in bite and feel and modulation when hot and cold.
I like these Porterfields, from their website...

"The Porterfield R-4 Carbon Kevlar pads have a unique, integrally molded ceramic heat shield designed specifically to minimize heat transfer in high temperature applications keeping caliper temperature at proper levels. These state-of-the-art materials offer tremendously high friction levels while at the same time extending rotor life.

Naturally, I chose their street compound.

I have no affiliation with Porterfield, just offering my experience with eliminating brake dust, I guess the other choice mentioned was Disc Italia.

how much? Im pretty sick of the dust too. Last I chked Akebono still didnt make pads for the w222.

Donnymac

On my 221, I had Akebono and dust was next to nothing. Huge improvement over OEM. Although brake pedal response was not the same, I never compared any measured results between OEM and Akebono.

I'm ready to swap out OEM but I didn't realize Akebono was without 222 hardware.

Here is my invoice..

One more thing, I had chance to drive my wife's X3 yesterday and the now my brake feel is similar to BMW brakes. As a side by side comparison, the Mercedes brakes have more bite with less pedal pressure than the BMW brakes.
This pretty much describes how my new pads feel, just like BMW bakes. The loaner C class I just drove had that Mercedes brake feel as well, kind of grabby, especially at low speeds.
I hope this helps anyone considering a switch out to Porterfield's.

I thought you'd say "I didn't drive the car anymore" haha.

This is great. I love the Akebonos on my Bimmer and I was looking for dust mitigating brake pad option to use with OEM rotors. I’ll check this out.

Here are some pics after almost three weeks of driving, about 1200 miles.
I even hit a light drizzle and rain storm.
The car stays pretty clean too, ceramic coating.......
Sorry for the lousy iPhone pics, but I think you can get the picture.

Front wheel

I am very happy!
Even the barrels are pretty dust free.

amazing.

I wished they offered these for 2018 S63's. Your wheels looks great though I'd delete that picture of your receipt since it has your home address, #, etc on it. So many scammers online from what I hear, I don't know, I don't think I'd never post a receipt with my home address, name and phone # on it. Just trying to help.

Thanks for the heads up.

300 for pads while I think is worth it, however Akebonos were about 150 for the whole car on my last s550.

stever500

Thank you. I thought the 2018 S63's had a different size, type, something... maybe that person was wrong. The cheapest price I could find 2 years ago was around $900 or so for new "top of the line" ceramic brake pads all around, from some vendor, I can't remember. Rock Auto? Not sure. The brake pad link you sent me had this review as one of the 3. I so wish my car was ordered with the gold carbon ceramic brakes. So much better in every way.

Very disappointed, been on my car for less than a week and the squealing is unbearable, NOT RECOMMENDED .
****Only manufacturer I have seen with ONLY A 30 day warranty on brake pads!!!!

No squealing here but racing pads tend to squeal like crazy until they get up to temp.

So far, I have no squealing or problems of any kind with my Porterfields. I hope it continues as so.

Hey Todd!
Thinking about getting the Porterfields! How did they hold up and what rotors did you use? Thanks!

Todd in PA

I have stock rotors.

After two years of driving how much did the Porterfields brake pads wear ??
