Unfortunately, I don't have any pictures of my own springs or shocks. I was in a hurry to have them installed and actually, didn't think I'd even update my website with pictures of the S4. But, what I got were H&R Race springs for the S4.
The springs lowered the car by about 2.5+ inches all the way around. I mean, the car was literally slammed. It looked drastic for the street and dare I say, "ricey", but it handled very well...so long as the street was smooth. I had a horrible time during the short period I had these springs in the car. They are just too stiff and too low for a daily driver car.
I can't remember how many time I slammed down on the framerail of the car because I went over a speedbump just a tad too quickly. Streets are going to have holes, big and small. The S4 just did not like anything other than a nice smooth stretch of asphalt, after the H&R springs were in the car. I blew one of my Koni adjustables during the time I had the springs in the car, and I think it was because the springs were too low. The last straw was when my wife borrowed the car, hit a bump and everything in the cup holder spilled out onto the dash. Besides getting an earfull about how the car was too low, too stiff and too bumpy, I had to clean the car up.
I then went to and Eibach Pro Kit.
I knew Eibach had a reputation for a very conservative drop and that's what I wanted. I really didn't expect the H&Rs to drop the car THAT much. So, I figured, better safe than sorry. I had known people that had Eibachs, who complained they weren't stiff enough and didn't drop the car enough. This sounded exactly like what I wanted. I just wanted to fill in the wheelwell a little. After installation, the difference was immediate. The ride was 100x better and the car was higher, but the wheelwell gaps were filled. Here's what the car looks like after lowering:
As referenced above, the car is also on Koni adjustables:
Unlike the picture above, the Konis for the S4 aren't the easiest to adjust. The picture above, and the Konis in my M5, use a knob for adjustment. You just put the knob on the top of the shock, and twist. Unfortunately, the ones for the S4 were not externally adjustable. They were internally adjustable. So, in order to adjust then, you have to fully compress the shock, and twist the shaft. A total pain in the ass and pretty damn inconvenient. I just set them to the middle and have never dickered with them since. They seem fine to me, although if they ever come out, I'll go a smudge stiffer.
I also have a Neuspeed rear anti-roll bar to try and dial out some of the understeer that is inherent in the car:
