Hi Cristo,
did see this thread of yours when I was searching. Don't think answering any of above will help as my springs have been replaced since new by an independant mini garage. That is why I am now trying to ascertain whether the springs are SS+ or not. So we match colours on front pair but not rears. Funny yours are grey as I have checked in my cellar today and I still have a almost new pair of springs off my old ONE from 4 years back and the rears are grey???
anyway, here we go: my car is a MCS(so should have SS+ from factory),manual, with storage, fogs, and HK....nothing else on your list.
