That much drop, you will destroy your stock shocks very quickly because their piston travel isn't designed for it. Labor overlaps so much cheaper to install springs and shocks at the same time. Bilstein B8 shocks are a nice choice and are designed for dropped springs. Another to consider is the Koni Yellow Sport. Bilstein have only one factory default setting, but Koni are adjustable on the car for damping level so you can customize the ride to your liking.

Hope this helps!
Are they cheaper than $206 buying from US retailers? I know nothing about suspension so thanks for all the info and tips about changing shocks too lol.
Since you are xDrive and in NYC with horrible roads I would definitely not install that Eibach part number. The drop is too great.

See the Eibach springs part number in the attached photo with the -06 in it. This is a more moderate drop of 0.8" front and 0.6" rear. With the NYC roads I'd install Koni Special Active Shocks with the springs for the best combination of sporty handling and road comfort.

I've driven my car with these mild drop Eibachs and Koni Special Active Shocks around NYC and they handle the rough roads very well.

Avoid 19" wheels and their low sidewall tires since many guys in your NYC area complain about hitting potholes and damaging tires. One thing that you can do, assuming that you have a square 18" wheel setup with maybe the 400M BMW wheels is to change your tire model and size.

Runflats ride very rough on bad roads and are more likely to be damaged by developing big bubbles on the sidewall when they hit a pothole. Changing to non-runflats will drive so much smoother even when you hit a pothole. They soak up potholes smoothly compared to runflats and their jaw jarring. The tire size can be upgraded from a typical standard 225/45-18 to a 245/45-18. The extra width makes handling so much better and the accompanying sidewall makes the ride even more comfortable. There is also the added feature of taking up more fender gap so the car will appear to have been dropped without being dropped. Even better to handle snow in winter.

Michelin Pilot Sport 4S are fantastic summer tires (only above 40 degrees Fahrenheit) A great year round All Season tire like the Michelin PS AS 3+ in a 245/45-18 would be great in the city.

Hope this helps!
