Well, about 5k into my ownership of the AS5's, and I'm very happy with them. They feel nice and smooth for when I'm not hoofing it (which is most of the time as this 2015 Focus 1.5 TDI is for moving the kids around), but when I do hoof it, there is plenty grip available. More so than the capabilities of the car, or me really. I had PS4's on my Edition 30, and while that was obviously a different animal, on the same roads, I could carry similar sorts of speeds through the corners. So a thumbs up from me. They feel better than the AS3's I had on one of my old 330i's, so thats a nice improvement.
As for wear. After 5,000 miles (roughly), I just measured 7mm across the fronts and rears. Seems decent to me, and VERY similar wear rates to the PS4's I had on the ED30.
Basically, given the choice between these and PS4's, I would be happy with either, and would go on price at this point.
