ok,first of all id change the top mounts (about £70 a pair from the dealer) worth changing,they do wear out and then you get a knocking noise from the front,and you dont want strip the suspension again,do it when you change the springs. All you need is a set of springs thats it ! (unless like me you get seized track rod ends) which will cost you around £20 the pair.I have some springs off a 2.0 tdi (sport) which are lower...you need to find out if the tdi's will fit your petrol 1.6(if ya interested)
