My bilstein dist here in chitown shows an app for the sport shocks on the 5ktq, for me it was a price issue, I think my racersnet price was in the neighborhood of $900 for the set... this was 2 yrs ago, and I went with the Sachs sport guys... Anyone out there give some compare on the sachs vs. boge on the 5k/v8 app. Scott PDQSHIP@AOL.COM
