Just got in touch with Tirerack and they dont have lowering springs for the A6 anymore!

Any suggestions where I can get?

Did you do a quick search on line, there's tons of other places that carry Eibach for the base 3.2 Fronttrak A6. What about H&R Springs? Although you may drop a little (say 1/4 inch) more in the rear on H&R's.
