Soooo, I want to take out my coilovers and replace them with the originals or as near to them as possible. I was advised that the back ones could be taken out no problem and a replacement would not be needed but apparently the front strut and things will be needed to be changed or altered, I'm not sure what is needed to be done. I just want to take out both rear and front coilovers and get it back to sitting at normal height, what is needed to be done and bought thankyou!! Will other models of lupos have similar parts that I need? p.s it is a 1.4 vw lupo tdi sport 2003
