mparallels

I'd like to lower the car so that it doesn't look like a 4x4 - can anyone recommend a decent set of springs for the E38 which actually make a visible difference? I have 18" m-pars on mine. I've heard a lot of springs which say 50mm lower or whatever don't actually make any difference at all...

Just upgraded the alloys on my E38 Sport to 20" Alpinas. Will be posting photos soon :) Before anyone asks the Parallels have been sold to a friend who wanted them for his E39 (he will need to get them bored out to fit). thanks.
