Bilstein streetline shocks worry me a little.
This is based on my knowledge of 205's the fronts are good stuff, but the rears are as arse as arse can be - supposed to give a very wobbly ride that can snap on you very quickly.
I'd be interested to hear how they feel on the heavier golf as i'm looking for replacement rears at the moment propbaly just going to put on gsf/eurocarparts stuff, but could be tempted to go Billie all round if reports are good.
