Delrin or Poly bushings? Worth it?

[David]

OK, I'm getting to redo the front suspension on my car. I'm considering either Blau's Delrin Kit or QuattroSpeed's Powerflex polyurethane bushings. Both are about the same price. The Blau kit only comes with 4 control arm bearings and new hardware. The Powerflex polyurethane bushings/bearing kit does NOT come with hardware but comes with 4 control arm bearings, plus rear beam mounts and panhard mounts.

But my question is...on a car like mine with a somewhat stock suspension, will it make any noticable difference over new rubber Bushings?? My only suspension mods now are Boge TurboGas struts and a 4Kq sway bar. I'm considering putting on a set of early typ89 Eibach springs up front (should keep stock ride height but be a bit stiffer). So, what do you think?  Please discuss...
