Lowered Suspension Problem

I started getting a strange problem with the suspension going over speed bumps and coming off a curb.

It would make a clanging noise, originally suspected to be springs bedding in, it was annoying enough to make the trip back to Amd.
They told me that "its never hapened before" and I was unable to demonstrate it. :o(

But these springs sit in a compressed state and logic "to me" says when a spring is uncompressed, its going to return to compression and possibly
slam back making a noise. Amd called a distributor who had a new "spring modification", or fish tank nylon hose, in my opinion! :o)
BUT it works, there is no more noise problem.

You'll notice in the last picture the car has raised slightly because of the hose, I think this brings the ride height to a nice level,
at around 20mm its S-Line/2002 spec and looks just right.
