I'm just going to get this started and hopefully others over time will add their own experiences to the thread. I initially thought brakes, rotors, suspension, etc. would have been shared with the outgoing W205. I am wrong on all accounts. Here are the factory equipped options/specs.
Rear of RZX wheel option and Part Number:
Picture of OEM bolt. 45mm length post collar/head. Smooth/tapered shaft found on other Mercedes Benz models.
Picture of front calipers - different than W205.
I have ordered some OE replacement bolts (from another MB model) to run a 6mm spacer and will post more once I confirm it is the correct equipment. 6mm upfront is perfect for OEM ride height. I'd probably run a 8mm in the rear if I could but for now I'm just going to run the 6mm on all 4 corners.

Stay tuned for more.
Thank you! Glad we have a similar thread like the W205. Excited to see everyone's build and to customize things to make it uniquely their car.
Going back to what a very valuable member has shared - I believe these are the correct lug bolts to run for a ~5mm spacer on the 19 or 20 inch factory wheels. I have had to order a couple different bolts to get to this place.
I should be able to share, visually, what 6mm on all 4 corners looks like tomorrow.
It's difficult to recommend alternative sizing for aftermarket wheels. The tire sizing really limits to slight manipulation on the front with something like 19x8.5et45 w/ 245/40/19 (this same thing can similarly be ran with 20's)
The rear almost needs to stay at the 9.5 width and can go down to et53 through OEM offset at et61.
To upsize the rear you'd need to run something like a 19x10.5et68 w/ a 305/30/19 - and I'm not sure what clearance limitations you may run into with something like that. When the c63 specs are out we should have a better idea of what we can put in the rear.
Like pretty much every 4,000 lb car that is AWD - the front end could probably benefit to have more tire. Something like a 255 should totally work in terms of fitment on this car where it was pretty much impossible on the W205 C43.
This is 6mm front and rear (I'd probably prefer the 5mm upfront as opposed to 6mm and might make that change in the future):
While there is more room in the rear - I really like where the rear is. I feel like an extremely flush setup works best without as much fender gap. Without lowering the car a wheel that sits in slightly helps guise the fender gap while very flush wheels accentuates the fender gap. The front is right on the cusp of having that problem with 6mm and 5mm would overall look better IMO.
Couple more to show the setup. You can see the front fenders flare out quite a bit all the way at the top but slim in quite a bit. If the car was lowered you could probably run pretty aggressive fitment compared to stock offset/widths.

Do you think with lowering it, the rear wheel steering fitment could rub?

depends on how low

you don't need hub centric for this small of a spacer - wheel still has plenty of OEM hub to mount to. The 12mm's I tested were hub centric for instance.
I ended up w/ 3mm front and 6mm rear - looks more balanced for me especially at stock ride height. 5x112 w/ bore of 66.56 for the spacers. The aforementioned bolts would be my pick.

The previous generation has no inner clearance if you go 8.5 with higher offset than ET32. I wonder if it's different for the W206. Can someone kindly take a picture of the inner clearance for the front wheels?

The stock wheels are already closer inboard than 8.5 et32.
In order to have the exact inner clearance with the 9-inch width wheels for the front. The wheel spec has to be at least 20x9 ET30. But it will be poked out 25.7mm versus the stock wheel. This spec will definitely be too aggressive for the W206. I am wondering if this chassis can get away with 20x9 ET40, which will move the wheel about 10mm closer to the strut and poke out 15.7mm more than stock.
If any of you guys can provide some pictures of the inner clearance between the oem wheels and strut/control arms, that would be greatly appreciated.

I've been looking at aftermarket wheel options and found that Savini is the only company I could find that makes a 20 inch wheel that would bolt right up without custom offsets, etc.
These are available in different finishes, can use OEM tire sizes and would not require any spacers to have a flush look.

Yes I found that also. Not familiar with this company/brand. Is it a good/quality wheel?
