I've owned my 2001 4.2 (sport I think) for 3 years. Instead of purchasing another used Audi (probably a S4) I have decided to put a few grand into my 126,000 mile A6.

Car currently rides fine, but a little too soft for my tastes and I think the car would look better an inch or so lower. KW has introduced the ST coilover and some vendors are offering it for about the price of good shocks and springs.

Worthwhile investment or not?
