Great replacement for my 2004 330xi standard-suspension sedan. The new springs had the same general shape and number of rings as the originals. They were a bit taller, but that's to be expected, given that the originals were constantly compressed by chassis weight over 17 years. I wish they came with an alignment marker, but it's not a big deal; i just paid attention to the original spring orientation before removing.
Get new upper and lower spring pads. If it's been long enough that you need to replace your coil springs, those will be worn out as well.
