Suspension Question - KW vs. Bilstein w/ Eibach Sprigns

[Bayerische E53]

Hi everyone,

I have tried quite a bit of searching and cannot seem to find a quality comparison between a KW coilover setup vs. a Bilstein HD setup with Eibach Sport springs.

What I have found is that people using OEM springs with Bilstein HD shocks hate the setup. However, I can't really find any comment as to whether the Bilstein HD shocks work well with the Eibach Sport springs. I also can't find any discussion regarding what setup is better - the Eibach Sport/Bilstein HD or KW V3.

One thing that sort of makes me skeptical of the KW shocks is that they are twin-tube, rather than mono-tube construction (the "racer" in me doesn't like that - I even tried offering AST a boatload of money to make me a custom setup because I have their stuff on my race car and I like it (mono-tube really is the way to go); but they refused to work with me. I'm not trying to be high and mighty but I know it may come off that way. Blah blah blah).

I need to buy something pretty soon here so I'd appreciate any feedback.

Thanks, all!
