''At this point the back suspention was low,''

^ ^ ^ this says it all, the car drooped before they could add springs to the invoice.

I may seem a bit cynical, but you get so many stories of the big chains of tyre and exhaust fitters finding other defects whilst doing their job, defects which they can repair but which they will make a total codge of if you let them do it! My own experience of rear dampers on my 2006 Tdci is that one started leaking at just three years old and failed completely whilst I was waiting to book it in. They spotted both dampers leaking, but neither of them had actually failed. Strange, that. The proper Ford dampers come complete with the flexible plastic weatherproofing tube over the top. The old ones will be cracked and disintegrating, so you wouldn't want to re-use them. Now - the front springs on the Diesel Fiesta are heftier than those for the petrol, in order to support the extra engine weight. I am having a deal of difficulty in finding out if the back ones are similarly different. If any other contibutors know the answer, please tell. Anyway, if you are regularly carrying back seat passengers, then the Tdci van back springs should do. But why is it low with the new springs that they've fitted? Have they fitted the dampers or springs or both for the model with lowered suspension? Try removing the bottom fixing bolt on one of the dampers (15mm socket) and see if the dampers are too short and holding the back end down. I think it would be wise to cut your losses. Find a local garage with a good reputation and let them have a look. --- And mine's done 160K miles now and still on the same back springs.
