Well, the stance isn't what I wanted, because I've been wanting more of a rake look (that's why I'm getting some coilovers soon) but I couldn't wait, so I went with these. The ride quality is decent, but I wouldn't know if anything was better because the only lowered xB I've been in is my own. Makes the car handle very well though. So ride quality could probably be beat (like I said, I wouldn't know) but the handling is very nice. And if you want the flat stance where everything's perfectly even, these would be awesome for that.
I have the Eibach pro spring set up and it used to sit perfectly level which is ok but not really what I was looking for. I have a lot of sound system weight in the back (subs, amps etc.) so now the box sits lower in the back than it does in the front. I am either going with coilovers or bags in the near future to get the box to sit the way I like.
