Is it possible to do a square setup with either:

11.5x22 818m OEM wheels
Or
10.5x21 818m OEM wheels

Ive seen one thread where a guy ran the 21s square and it seemed fine. Any reason I can't do the 22s?

It looks like the offset is ET43? You would have to probably use spacers to clear the inner suspension and probably the brake calipers. 21x10.5 already fit the fronts, clearing brakes and all.. He probably spaced the rears out to get them as flush as the fronts too I'm sure

I'm only going to analyze the front wheels in this post since both the 21" and 22" 818M wheels will fit the G05 rear.

The front wheels on the G05 platform are 22x9.5" +37mm. When comparing to the 22x11.5" +43mm sizing, the 818M 11.5" wheel will be 31mm closer to the suspension components. So this wheel will 100% not fit in the front.

When comparing to the 21x10.5" +31mm sizing, the 818M 10.5" wheel will be 7mm closer to the suspension components, this should fit in the front. With that said, the wheel will stick out 19mm farther towards the fender than the regular G05 21" wheels. I've seen some members run 15-20mm spacers in the front when their cars are lowered or have air suspension, so this is reasonable. My car is not lowered and I have a 12mm spacer in the front, wheel sits flush, 19mm will be way too aggressive in my case.
