Koni's for the front are 8741 1535 l/r sport, fits all 3 series xi models.
Besides the extra time diagnosing the bump stops, the install was surprisingly easy. Its more of a mental thing. After this experience, I would rather do struts and springs on the bmw than replace a serpintine belt on an Audi. You have to remove the entire front end and push out the radiator support to get an extra 3" to get to the belt. I had to do mine earlier this year on my old S4 cabrio.
All said and done, I haven't looked back besides sharing my experience. Well worth the time and effort for the results, both looks and handling. I felt the car had way too much power for the suspension. Missed shifts due to nose lift as well as front wheel scratch during heavy trottle.
Just because you have an awd car doesn't mean you need all that extra ground clearance.
