Well I guess we'll find out soon.... I have 285/30s on the way for these 19x9.5s.
Running these in the rear will give me a 3mm sidewall difference than in the front. Does anyone think that's going to be an issue on an AWD car? I know drastic diameter differences can cause issues, however, with this set up I will only have a 6mm total diameter difference.

Ask your differential every time your running at highway speeds.
I tried the exact same fitment and it was a decisive no-go on the front. It might have cleared the rear - can't remember. Tried the Pirelli P-Corsa's (60 treadwear!)- VERY wide for the size, made my 275's look like 255's. Sure would have been fun...
Tire pressure will likely make a bigger difference on the rolling diameter than the width increase. If the front tires are smaller will increase the effect due to heavy front end. The center diff might work a bit more than it's designed to, but have yet to hear of any related failures. Change that oil- frequently.
I run a square setup to keep things even as possible and for better handling.

So I'll have 255/35 in the front and 285/30 in back. Therefore, the fronts will be a total of 7mm taller. I'm thinking a little more air in the back should even things out. I'd love to run 295s, as that would make front and rear diameters even, but I don't think 295s will fit. I could also go down to a 245 up front and have even diameter that way.

295s will fit with a bit of fender rolling.
7mm difference is significant, your diff won't like it.
Also, I warn you once again - it'll handle awfully.

But now you have me worried... Is a 1.2% difference in diameter really going to cause issues? I've heard within 3-4% of diameter on a Quattro is ok.

Likely won't manifest itself instantly. And manual transmissions are cheap enough.
Edit:
Disregard. I have 255s on these 8.5 wheels now. Just gonna run the 9.5s in the rear with 255s for the time being.

I love these wheels, can anyone on here advise if they will fit? TIA

Not sure that this is helpful, but my Volk GR V2's were 19x9.5 and had a ET29. 19 might be a bit aggressive?
2013 Audi S8
19x9 ET24 on the outside is pretty much equal to 19x9.5 ET29 (actually 1mm deeper into the wheel well).
19x9 ET19 will stick out 5mm further.
Thank you for this information very helpful, it's a tough decision these are my dream HRE wheels for the beast & they are priced very reasonably for HRE's, however I currently run a square setup (OEM RS4) which fit great & square seems to be the preferred SOP for these beasts so I am deliberating if the understeeer is a worthwhile tradeoff for the look of running these staggered HRE's (if they were only a square set up. In any case thank you for educating me further via your helpful post

5mm difference in offset won't be much of a problem IMO (as long as they fit in the wheel well) and as long as you put identical tires on them.
In the original "anti-staggered" post I was advocating against different sized tires front/rear.
