This finally came in today after placing an order on 5/12/14. I plan on having this installed on my 2005 SLK55 next week. Paid $905 shipped, which I think is reasonable for Bilstein Sport/B8 shocks and discontinued Eibach Pro-Kit springs. Bilstein Sport shocks fit the SLK55 and members have installed Eibach springs on the SLK55 without any issues. I shouldn't have any fitment issues with this kit, hopefully. I also have the SPC rear camber kit to be installed at the same time. Thanks to Durk, I'll look into spacers for the stock wheels after everything is said and done.
