OP, you are not supposed to modify the overall diameter of your OE wheel/tire combination, so dropping the ride height should not really be necessary for that purpose. Find a tire size that keeps your overall diameter as close to OE as possible.
I have 19's on my current car. I think 19's look brilliant, but while turn-in is crisp, I feel like 18's would have been better for handling. You can feel the car become a bit unsettled because the rest of the chassis is not ready for the sharper response. It's like the two are not in harmony.
For a street car, you have to do something drastic to notice, but I'm sure with enough options and time you might find a better combination than what the BMW engineers have come up with to improve on handling.
