The 35 weighs 165lb's more, so I'm not sure if that negates the bigger brakes stopping in a shorter distance.
The 35 also is a 52.1/47.9 weight distribution vs the 50.6/49.4 of the 28. A local SA said there is a noticeable difference but I would think occupants would affect the distribution more, am I wrong? 3 series xdrive28i is 51.3/48.7 for reference, and the xdrive35i is 52.2/47.8.

It could be related to pads too, but the pedal feel sure felt better on the 35i and is one of the reasons we chose it over the 28i. I'd guess initial stopping differences aren't all that different, but the capability of the 35i's larger rotors to dissipate heat is much, much better, not only are they taller, but they're also significantly thicker and better vaned, so braking distances over multiple stops should start to show sizable advantages.
