Haven't you been in my Fiesta before?, lol
I've been chopping springs for years, its just a metal rod wound into a coil, they usually get cut in the factory but you may as well do it at home.
My XR2 had lowering springs that were chopped as did my 1300 Sport.
My 1300 Sport failed its MOT on a broken spring so I took the other one out and cut it to match, painted them both black and the MOT man thought I purchased two new springs !!
If the rides a bit bumpy after cutting, its 'cos your still on stock dampers..
