670mm from the ground to the arch is the standard height, if I recall.
It seems to be a common thing that the wheel arch gaps look ridiculous when fitting new OEM springs. Either VW changed them over the years, or the originals just sagged and snapped.....or something. I remember replacing springs on my Corrado years ago and the back was so high, you could put a coke can on the tyre and still be an inch clear of the arch. VW double checked the part numbers and they were right. Weird.
