Don't be fooled into paying more for an RS6 specific suspension, because it's baloney... Other than the DRC, this suspension is the same as the A6. If you buy adjustable struts or coil overs, you will always think you could have adjusted them better... I like the fixed style, simple, and nothing to worry about, and totally reliable..
Due to the cars lower height, you must use the Bilstein Sport Strut, because the rod is shorter and will not bottom out with the RS6 lower ride height.
I spoke to the head tech at my dealership yesterday about the DRC. He said that the ride height should not be affected by the DRC pressure. I know that counters what I've read on this forum, but that's what the techs are taught anyway. If the car sits higher after the recall, it's probably due to the position the control arms were in when the were re-torqued. The car sits on the springs, not the shocks..He said that clunking indicates that not enough fluid was injected into the sytem on install.Not so much a pressure issue.. Either way, it seems to me this is a problem that will never go away, and I hate the fact I lack the tools to fix it myself, as that is the only way in my mind the DRC will ever work correctly. I cannot tolerate a rattly clunking car.. And I cannot bring myself to pay the dealer to do what I do all day long...
My DRC replacement strategy is go cheap, yet sufficient. All you really need to do, is replace the struts and sway bars, as long as you are happy with the ride height, as is stock.. Some Bilsteins have grooves cut in them, so you can lower the spring perch, thus lowering the car. If the back sits too low, you can also raise it up if need be..
I want my car to handle crisp, but lets face it, this car is not a race car. It is big and heavy, and will never handle like a RS4 or M3. Sure, you can kill the ride quality and make it ride like a hay wagon, deriving slightly more responsiveness and lateral traction in the process, but IMHO, not enough to make it worth while. The car is not balanced, and that is very hard to overcome..
I'm gonna give the dealer one shot to fix it right, but if they BS me, or try to charge me, I'm going to do what I proposed above.
