Recommendations for 535i m sport? Looking for cost effective solution. Separate wheels and tires? Swap tires?

It's my DD and use all season and I do fine.
I can't imagine your winter is much different than mine.

If your BMW is a RWD and if you intend to keep you car for a number of years, go with separate winter tires and wheels. Generally inexpensive ones on all four corners will work fine (and not much differently than expensive ones like Blizzaks and Michelins). Go with smallest rims that will clear your brake calipers and the narrowest stock tires that work with your car - possibly 17" wheels. Often winter tires are a size narrower than summer tires because they cut through the snow to the road surface rather than riding up on it as wider tires are inclined to do. You'll be surprised at how well dedicated winter tires work even with a RWD vehicle. BTW, most people think of winter tires for driving forward on snow-covered roads. Actually, they are just as important for stopping on snow and ice.

How to check if 17s off of a non-sport model fit my M-sport that currently uses the 19s? Are brakes different on the M-sport package models?

What did you end doing? I'm in similar situation. I have the 19s with the stock summer touring bridgestones.

Like your M-sport, my 535d xdrive came with OE 19" wheels, but 17" wheels (like BMW style 327) also fit. I don't believe the brakes were any larger with the M-sport option on a 535d.
