Update: All sorted, the wider, shorter, non-bunched up ones are the fronts, and the taller, narrower ones with the bunched up end are the rears.
Need to send off some rear springs, and I'm just double checking to make sure I don't stuff up... which ones here are the rears? (i.e. 1st & 2nd or 3rd & 4th)
They're GC8 STI springs if it makes any difference. Looked on my car but can't see which one has the bunched-up coil end.
