For sport springs....
Yeah, different answers from Bilstein is maddening. Not wanting to re-ignite the debate but with info. from them and Turner I've concluded that B6's are for 0-25mm (1") drop. That includes all BMW springs, Sport Pkg. and Performance. Over 1" is B8. Turner backs this by advising B8's are not recommended for any OE springs including Sport Pkg./ Performance. On the short term many seem to disregard this with no apparent problems. My personal experience is that if you're happy with your ride height, the B6's with Sport Pkg. springs work very nicely indeed.
