Fitment help

Anyone knowledgeable with 5×114.3 wheel fitment on a 2018 wrx:

I am currently running 18×9.5+40 with 20mm hubcentric spacers all around, but would like my next set not have to have spacers. I have tried using some online calculators but I know it's not always 100% visually accurate. I am wondering if ≈18×10+22 will fit similarly to this without needing spacers?

I'm not extremely knowledgeable on offsets and fitment, kind of just learning as I go.

I am currently running 235/40 tires but they are too meaty still and want to get 225/35 stretched next.

I also plan to slot the front coils to match the camber front and rear and have better fender to lip fitment all around.

Also wondering if anyone knows a good site to source chrome spinners for 5×114.3 wheels, just a thought.

Any input, help, or suggestions are greatly appreciated 👍🏽

Thanks in advance.
