I know you can retrofit the entire brake setup, but has anyone used the 2-piece E63 rotors on an E550? From what I've found, the rotors are the same size, although I don't know if the hat offset is different. I'm considering going to the 2-piece Brembo replacement rotor setup for the E63 if the hat offsets are the same, as that will lose a ton of unsprung weight and should improve brake cooling a bit.
Also, has anyone just done front E63 brakes without doing the rears? I'm wondering what that will do to the brake balance and if there are any master cylinder sizing issues to consider. I definitely don't want to cause issues with stability control and ABS.
do we know if the pads are interchangeable? girodisk shows the same part number for the 2pc rotors so i thinks its safe to say the rotors are the same.

does the E550 have floating calibers or fixed ones like the AMG uses ? floating calibers only have pistons on one side, fixed calibers have them on both sides. I doubt the same shoes fit both styles.

Yes the E63 rotors will fit the E550 without issue

This should not be a issue since your actually making the braking system do less work by going with lighter rotors

Im not sure about the pre-facelift models but the 2014 + W212 E550 have fixed Brembo calipers

so then its just a matter of whether they have the same calibers. I dunno the right model numbers to look up, like my wagon is a 212.288, so what is a facelift US E550, and a E63S sedan vs wagon ? given that, I should be able to look up the part numbers for the calibers and pads.
(started to try and figure out models, but there's way too many 212.XXX submodels for me to make sense of)

The pads and calipers are NOT the same. the E63 has more pistons. E550 only has 4 pistons

Correct the 2012-2016(2012-2014 in the US) W212 S212 E550/E500's have Brembo 4 piston calipers, the E63's have Brembo 6 piston calipers. The pads are different the rotors are the same size.
There is a set of front and rear calipers/rotors from an E63 for sale in the classifieds. I don't know if it is a direct swap or not, if it is though that seems like a reasonable route to better brakes if that is what you are looking for.

I dont think that will work. Without checking , I think the E63 hubs are different. Even if they did fit , you would get a noticeable difference in breaking. I car stopped great from triple digits everyday. Currently using Brembo rotors and TRW pads from FCP Euro. I put the TRW ceramics on knowing the I would hate them. I previous experience with ceramics on other cars were bad. I was proven wrong with these TRWs. Anyway you should look into better tires if breaking is a issue for you with the stock setup

I don't race anymore... When in the mood, I drive briskly. and I do drive quite a lot on mountain roads, narrow 1.5 and 2-lane as well as 4-lane state highways. I have had to make several faster-than-normal stops due to idiots around me that might have ended very badly, but the stock E350 Luxury brakes hammered that car down from fast to slow without a hint of drama and no hint of fade or warp yet. now, we've only had this car about 6 moths, and I think we've put about 5000 miles on it. So the proof may still be in the pudding.
My son, who's been driving a BMW 530ti awd wagon the last year or two, when he drove it to the airport with my wife as a passenger, he pronounced it a boat... but he's been driving a beater version of this car...

The hub is same dimension for the rotor mounting, but I'm not sure if the caliper mounting is the same. I'm pretty sure it's bolt-on, as I know some people with W212 E550 M278 cars have done this upgrade. The heat capacity would be better with the bigger brakes- I've already gotten my brakes pretty hot from hustling the car on a tight, twisty road. I think there is too much ESP intervention and the stock pads can't handle that kind of abuse.
The biggest question that I've forgotten to ask- do the E63 brake calipers differ from pre- and post-facelift cars? I've seen the earlier, RWD E63 with 18" factory wheels mounted, but the later cars seem to all have 19" wheels. Did they increase the size of the calipers or were the older E63 rotors smaller?
