We just fitted the Paddocks kit to our 200tdi and it looks great. Our way of thinking was you might as well get everything you might need to start off with to save any messing around in the future. Not only do you get the extended hoses, you also get extended bump stops and disslocation cones.
If you just fit springs and shocks, then find out in a few weeks time that you need extended hoses, disslocation cones and extended bump stops you're going to be pretty fed up if you have to take everything to bits again, plus it will cost you more than buying the whole kit in the first place!
Go for the kit. Job's a good'un.
