Lowered the allroad and put some new wheels and tires. It sitting a little lower than I like but no rubbing and the ride quality isn't too bad. Here's some pics.
it looks like Continental Extreme contact 255/35/20 by looking close at the pics.

@brianmccauley1 on Instagram these are my personal views
I used the H&R coilovers made for the B8 avant. I wouldn't recommend them on the allroad. The fronts had enough adjustments, but the rears at its max height still tucked. I would go with a KW setup. From what I've read it has more rear height adjustment compared to the H&R's
