Looking to get some wheels, need specs
Going with 20's whats the norm?
10.5 rears, 10 up front?
can you do 10.5 all around?
what offsets are recommended?
I came from 20x10.5 et 25 all around and loved that aggressive look - can this be achieved or would you have to bump down to 19s?

I spent a lot of time dialing in the specs b4 having them machined and will share those numbers here.
First, the largest rims you can go are 10-1/2 rear and 9-1/2 front. These allow for a maximum of 305 tires in rear and 265’s in front. There is not enough clearance in the w212 for larger. I am running P4s tires but occasionally I throw on my Proxes 888’s in the rear for Dragy pulls. Keep un mind all of my numbers are on 19’s. So I can’t confirm fitment with my numbers on 20’s.
Offsets:
+50 rear
+35 front.
10-1/2 rear
9-1/2 front.

In the front, as mentioned, I have 265’s. Again square shoulder and flush stance with fenders like the rears.
I suppose you could go with a wider rim on these size tires with a triangular look, but what would be the advantage there? 🤷♂️
What am I missing in your post?
I currently have some Rotiform SRG wheels (which I will be posting for sale any day now), not sure on the offset because they came with the car. Im assuming they are 20x9.5 front and 10.5 rears - I'll be getting answers next week when i go into the mechanic.
The rears are 295/25 tires which isnt enough stretch for me, and I know what 255 looks like since that was my last size.
The fronts are 255/30 (is that normal to have different profiles on these cars) which isnt enough stretch for me as well.
So I am thinking about going right in the middle for the rears, at 275.
What would be the same amount of stretch on a 9.5 width wheel?
Wheels i will be posting, less than 500 miles on them, wrapped in PS 4S.

Our wheel/tire specs are nearly identical. As a matter of fact, I believe we commented on a thread you started before you got your BC Forged and based on that I decided against going w/ a 265/35 up front (Used to run a 275/35/19). Anywho... the only thing you are "missing" is considering that some people choose wheel/tire parameters for looks more so than for function. As OP has just confirmed, he is going for stance. I am sure you have seen pictures or maybe even sample in real life of cars that are dumped, have wheels that appear way too wide and more negative camber that the laws of physics should allow. Operating under those principles would allow the end user to run wheels that simply would not fit in the traditional sense of "fitting under the wheel well". The "advantage" of such non-conventional parameters is simply "aesthetics". Beauty is in the eye of the beholder.

Those Rotiforms are nice. I mean, the pic on the website looks great. I am sure they go for a pretty penny. I don't think I have ever seen a wheel company that offers more options to choose from. A true CUSTOM wheel. Have you pictures of the car w/ the wheels on?
Out of curiosity, how wide are you looking to go w/ your next set of wheels? These cars do not have camber adjustment from the factory; you'd have to go aftermarket.
19x10.5 et 27 and 25 (not sure which is front/rear). and tires are 225/35

And I don't think you can pull off the look you are after going static. Boy, you are gonna have to do some magic to squeeze a 10.5 +25 in the back of these cars

Do a build thread. Would love to see the end result!
Have fun w/ the build!

I did indeed miss the stance point. My bad. Lol
cheers

F20x10.0 +35 255/35/20
R20x10.5 +47 295/30/20 (might be better for the reason below to go with +50)
Slight rub at high speed/bumps nothing major. However the car will rub alot if the car is in sport or sport plus suspension. I never drive the car in sport+ suspension anyways rides like crap.
Previous setup was on 295/25 and 265/30 with zero rubbing. However broke two rims due to lack of tire sidewall. This setup been much better.
