First off, I am so impressed with the wealth of knowlege you F10 posters have. Respect.
It seems I will be rolling with my OEM staggered 19" Factory style 331 wheels for a while. I know many have put spacers on the rear to bring them flush with the fender.
By knowing the ideal offset for after market wheels, I was thinking that we can calculate how much offset is needed for the OEM wheels. I love wheels/rims with an aggressive flush stance and offset. As my title says, my goal is for my OEM wheels to sit flush and aggressive like many of the aftermarket wheels.
These are my wheels:
Front Wheels are BMW Part # 36116790178 8.5" x 19"
Front Tires: 245/40R19
Rear Wheels are BMW Part # 36116790179 9" x 19"

Rear Tires: 275/35R19
