This site is even clearer about the results. http://www.gtsparkplugs.com/WheelOffsetCalc.html
Every inch change in wheel width is worth ~13mm in offset change (wheel width in inches, offset is in millimeters, 1”=25.4mm).
So if I change my wheel width in back from 10” to 9”, I’d want a +39 offset to keep the outside lip in the exact same plane as it’s in now (reduces total width by 25.4mm, divide that in half you get the 13mm that you need to shift the wheel center line back out, push the wheel out is lower offset, so you get 52-13=39), but that also means I would have a huge gap to the strut. That’s essentially what you’re asking about.
So a +38 will likely work fine for you depending on tire width (you may have to trim the bumper clip), but it’s pretty far from an ideal fitment.

Every inch change in wheel width is worth 13.5mm in offset change (wheel width in inches, offset is in millimeters, 1”=27mm).
So if I change my wheel width in back from 10” to 9”, I’d want a +38/39 offset to keep the outside lip in the exact same plane as it’s in now (reduces total width by 27mm, divide that in half you get the 13.5mm that you need to shift the wheel center line back out, push the wheel out is lower offset, so you get 52-13.5=38.5), but that also means I would have a huge gap to the strut.

You could’ve bought these wheels and tires for almost the same price.

Asking one more time, 19x9.5 +50 in the rear of my 2010 Mercedes c63 amg will work? I have stock 18x8 in the front and 18x9 in the rear. There saying 50 may be cutting it close, they suggested +38.
fyi, these are concave wheels... Niche Rainer M240.

Built 2008 G55 & one big 80 Series LandCruiser !
My build to spec before widebodying were 19x9.5 et 48 rear with a 275/30/19 - 255 in front on 19x8.5 et 40
those were spot on. ET50 might work..... might.

niche recommended front 19x8.5 +42 paired with rear19x9.5 +50.... but I don’t believe them cause they also said 20x10 +38 would work in the rears with 285/35/20.
