I have gone for just the eibach springs on my 110 se, (10 000 miles ago) it goes really well,doesn`t bounce. mind you its only got 22k on the clock so the shocks are still good. If youve done nearer 50 then probably best to go shocks too. I did recently think the shocks were getting dodgy on the back, took it to Midland vw where it was diagnosed as rear bushes, It is now very quiet and seems to be a pretty good set up over bumps with no crashing at all. Cost me £210 at the time shocks on top will double that price at least.
