Generally, looseness is either:

1. TREs (most common) or
2. Worn control arms, with integral bushings and ball joints ( as I 

Your springs are probably fine. They dont really wear much.

Your shocks, i cant speak on.  I find that audi "S" shocks tend to have 
little damping on crucial small stuff, yet crash on big stuff.

My discussions with various suspension manufacturers lead me to believe 
that matched coilover sets often provide the best ride/handling trade 
off.  They are often lower mass, and in the case of Bilstein, I know 
the factory engineers prefer the end result of the PSS9 over the 
HD/stock, at least on C5 applications.

The HDs are probably quite good. Many people seem to like Koni's FSD 
struts as well.

I'm also wading through this minefield with my C5 S6.  Mistakes are 
expensive and way too many success stories begin with "the new ride 
height looks bitchin". At whcih point I disregard the rest.
