I forgot to mention that I think they're a poor man's koni special active/fsd, with a similar variable damping, but with a couple of differences.

These Monroe OEspectrum shocks have been used in Audi and some other cars that marketed smooth yet quick handling...

I haven't tried the konis so I can't say they're equal to them, but I did shy away from koni because the reds I had on my vw tdi rusted quickly... when I heard they still have crap paint, I decided to try something else.
