2019 GLS63, about time to replace front brake pads. What are the options out there?

EBC Redstuff are working well on my 2017 GLS63. I think the part number is ​DP31939C, but please confirm for your 2019 model year.

Good bite, quiet, durable. I have 23K miles on this set so far, and they still have 1-2 mm left before change required.

The indenpendent shop recommends Raybestos, any experiences on that?

I've found the ceramics to have less initial bite but have very little brake dust and don't seem to wear the rotors as fast. Semi-metallics have great bite but throw off a ton of brake dust. Personally, I run ceramics since I can't stand the brake dust.

Agree. I also found that OEM front pads when combined with Brembo (instead of OEM) rotors, produce noticeably less brake dust. (Same observation for the rear with OEM pads with Brembo and/or Zimmermann rotors). Since initial bite is more important to me, I use OEM pads (or equivalent with GG compound). I would not use any front pad with inferior friction compound (those not marked GG).

I am mainly after stopping power, dust isn't a very big issue, advantage of black rims

Searched around found Porterfield R4-S seems pretty pouplar on other AMGs.

In my extensive research, I have not found a better stopping front pads specifically for X166/W166 63AMGs than OEM's front pads. Other brand pads people use on these heavy cars are really designed for cars line E/CLS 63AMGs. All above have identical dimensions hence "other" pads "fit", however MB is using specific p/ns on X166/W166 63AMGs which are different from all other 63AMGs even though the pads physically are identical.
