Anyone have these on their A6? My OE front shocks(comfort suspension) are beginning to show their age. I've used KYB products on my Volvos for many years with terrific results and was wondering how well they work on these cars. They're almost half the price of Konis or Bilsteins, but I obviously don't want to install them if they're going to wear out quickly or ride uncomfortably. Any input from experienced users will be greatly appreciated.
