Worth every penny.
They came a day early and I am happily riding on them now. I would recommend the H&R's to anyone. I had H&R springs with Bilstein shocks prior to the H&R coilovers I just got. I am still getting used to them, and they have been growing on me. First I noticed they felt a bit softer than the Bilsteins and I was a little displeased. However after about a week I realized that these may be superior to the Bilsteins and H&R springs. On the highway they ride unbelievable, and over bumps where my car used to bounce or jar, they glide over and feel way more controlled. It seems to me the harder you push the coilovers the better they perform over the spring/strut combo. Around town the springs/struts felt harder and tighter and more agile, as opposed to the coilovers which feel more like a regular suspension A6. However, like I said before when you push them harder they are far superior to the springs/struts. I thought about going with the PSS9's but I didn't want all the fuss of a million adjustments, because I already have another car with fully adjustable dampening and ride height, and unless you are track racing your car hard, it's just not worth it to me.
