I ordered Eibach Pro Kit springs and will probably have someone else install them for me as soon as I get them. I am eventually planning on redoing the whole suspension, struts, etc. but right now just the srpings. Is this ok, or do I need to redo everything when I put the springs on, or can I do each part gradually. A mechanic I know said I should redo the struts when I do the springs. If I don't he said the struts might end up leaking. Does anyone know if I can just do springs or do I need to do everything together. I'm still pretty new to working on cars and owning a Mustang. Thanks so much for the help. (I also orderd Flowmaster Cat-back exhaust, can't wait to get it all on)
