Performance impact of 19"/20" wheels

Does anyone have any concrete data on the performance impact of the 19" and 20" wheel upgrade options? I love the look of the 19s and especially the 20s but may not like the performance impact of that look.

I'm guessing about a 0.1s 0-60 impact for each 1" increase in diameter. Has any mag or BMW published numbers for the 19s or 20s? Paying good money to slow down the car makes me uneasy.

Would be good to even have weights of the different wheel options if they're available.
