Does anyone know if RS6 coilovers fit a 2001 A6 4.2 Sport?

I do have the Bilsteins available for the S6... they are about 1700 or 1800, call me if you are interested.

brand has the greatest height(raising/lowering)adjustability? In the future, I may attempt to convert my ar from air suspension to coilovers. Two ar owners have done the conversion. The big issue: because of the ar's suspension geometry is different from the S6/RS6, it needs great height adjustability. See link for conversion details.<ul><li><a href="http://www.allroadfaq.com/downloads/mods/allroad_coilover.pdf">http://www.allroadfaq.com/downloads/mods/allroad_coilover.pdf</a</li></ul>

And these are VERY new to me. I just do noy have much experience with these cars... working on it. Sorry I could not be of more help.

If you e-mail me I can send you pictures of the PSS9's... tjhis may help you judge adjustability.
