i'm not having any issues with mine at 95k but i just wanted to see how long i should expect to be able to go without replacing the stock shocks. i've done more than enough city driving on some terrible roads in downtown hartford (ct) and the aero setup is i think still doing fine. i am definitely going to go with the bilstein hds once the time comes, if not sooner. i just want to make sure i'm covered while i go out and replace the standard piping with 3" from the turbo back and elsewhere. i know it can vary with conditions and certainly between the different models of the 9-5 but though i'd ask to get some info. any takers?
