If your going to remove the S/L dampers, I could be interested in them if they are reasonably useable.
If you do that you must change from S/L spec springs. They are far too soft to stay on the car with normal spec dampers.
As mentioned above, rear springs are a bit of a nightmare to get right. The ones currently on the rear of my car have the rear sitting too high.
I seem to remember Doc Gollum recommending Kielen heavy duty for the rear, so will probably investigate that option when I get around to it.
The rear shocks have pipes leading up to them but they are not connected to them so assuming it's standard shocks on them. I'll need to have a look at shocks see if I can see any ID on them.
I had a look at Kilen springs and they only list non SL ones so imagine Dg was talking about changing over to non SL stuff.
