I am so tired of the name bashing in this place.......whether it's tires, suspension, exhausts, or air and oil filters, EVERYBODY has an opinion, and they are certainly entitled to it. However, these opinions can sway a member into a purchase that they may have never made otherwise. As for the guys @ Groton, I have personally used their stuff, and BELIEVE IT OR NOT, some of the Hamburg products have actually had the Lemforder "Owl" casted into the part. Since Hamburg Technic is a company that manufactures NOTHING, but instead buys overstocked inventory from the larger part manufacturers globally, you will often get Lemforder, Meyle, and even Sachs parts in the box. Here is the importer's website, give'em a call. http://www.eurostarinc.com/customer_service.shtml Just remember this, Bilstein was never offered as OEM on any E34, including the M5, yet if you read this forum, you'd be an ass for using anything but. I guess all those engineers over at BMW are asses for not using Grunt bushings, Triflo exhausts, Bruno's subframe inserts, or Bilstein shocks and struts. Who'd have thunk it?
