Not necessarily. If you have the m-sport suspension, you might only see 1/2" front & back. The drops listed are for those with standard suspension

My 07' 335i dropped around 3/4" in the front, and only 3/8 in the rear with the B12 Prokit.....I wish the front would have dropped another 1/4".....but the back is perfect. Overall I can't complain......looks lower than stock but not dropped. And it handles great!

Hows the handling now? Hows the ride quality with the B12 kit?

What setups were you each running before?
Stock struts/shocks/springs?

You'll have plenty of room for 17x9s. Plenty of finger gap all the way around. Its about the same height as regular sport on xdrives.

Ride quality is a little stiffer than sport. There's a very noticeable difference from stock. Improved handling makes up for the uncomfortableness (which is really only uncomfortable on rough roads at lower speeds). If you don't care for spirited driving (which I'm sure is not the case), the B4s would be better suited.

I was running the OEM shocks and springs....with around 90k miles on them. The ride was pretty soft....nothing to brag about.

With the B12 Prokit, it dropped the car a little bit (see my post above), and the ride really firmed up. It's almost to the point where if I had to drive on bumpy roads all the time....I would say that it's almost too firm......but I don't drive a lot of bumpy rough roads.

It's a firm ride, but not harsh. it's just about perfect.... I wouldn't want it any harder, or any softer. I'm pretty happy with the whole kit in general.
