Disclaimer, the specific tire you use, since same sizes among different brands can have different tread widths and rounded vs square shoulders, as well as what your plans are for ride height and camber settings will all have an impact.
FRONT:
20x10” et54 will not rub and allow a bit of lowering. 20x9.5” et48 will act the same with the width change.
REAR:
20x12” et62 is the way to go that does not rub and allows a bit of lowering.
Examples above will be in line with tread widths similar to Michelin Pilot Sport 4s 265 fronts and 325 rears, with a 10” wide wheel you can go up to 275 front, pretty much max in front of GTS.

That's a bit aggresive, no?
Fronts and rears would stick out ~18mm more than factory by my math on a GT/GTs.
No, that’s flush, no outside the wheel well “poke” and no rubbing.
That's still moving the face of the wheel 18.7mm more outboard than the stock wheels. Do you have any pics with wheels that sit flush with those offsets? I'm currently shopping for wheels and trying to see what folks are running.
18.7mm out seems a bit much for me, but for others that may look good. 10-13mm seems "flush" to my eye. I bought some cheap 5mm spacers to stack and see where I thought the wheels should sit in the garage for approximating wheel offsets and came up with the following:
Rear: 19x12 ET 68-70 (10.7-12.7mm more outboard than stock)
Front: 19x9.5 ET 59 (9.5mm more outboard than stock)

Stock wheels:
Rear: 20x11 ET 68
Front: 19x9 ET 62
Im pretty good with offsets for the platform or I wouldn’t have chimed in to spread mis-information, but please do as you wish 😁

Would this sizing work for 19 fronts and 20 rears?
I just had a look at your pics and it shows a 21 rear? I can see the front.
This is my first official post. thank you in advance for any help .
can someone confirm the below offsets will work?
After speaking with some wheel experts, i am looking at getting a new set of wheels with the following specs:
20x10 +50 and 20X12+58.-+60.
Does anyone think there will be issues rubbing? hoping this sits flush with how. my car sits at the moment.
and are 20x12 too aggressive? i can do 20x11.
again thank you in advance
You will be fine with those offsets, they are not that aggressive, no danger of rubbing.
I am running 20"x10" ET 47 with 265/30/20 michelin, and 20"x11" ET 48 with 315/30/20 michelin on my lowered GTS with a factory alignment and it doesn't rub, so you would be fine with a 20"x10" and a 20"x11". I don't know about the 20"x12" though.

hey bro are you saying I can run 20x9 with et 35??? If so what other mods if any did you have to do? I’ve stalked your pics, they look great.
all great info....
Since I am considering a GT- C with slightly wider fenders, I am wondering how much the offsets would change to put them flush with the fenders?
(keeping in mind that I would also want to close the wheel gap a little with a set of KW HAS springs).

I did Et45 (front) and Et33 (rear) when I had my BC Forged made. I'm also running KW HAS..we based the off sets on the spacers I was running that were 12.5/15. I pushed a little more outward in the front and a little.more inward on the rear. Really happy with the offsets I went it.
Hope that helps!

I see that you're sunbeam yellow?
This is my first color choice in my search for the perfect GT-C (with carbon ceramics, of course)!
