Usually when a manufacturer puts wider wheels on a car, they ingrease the positive offset so the outside edge of the wheel is in the same place, moving the centerline inwards. I suspect this is what the case is with the 323i/328i but I haven't checked the numbers like you have; I just went with DAT's numbers.. (n/m)

: : Track is measured at the centerline of the wheels. The 328i's wider wheels put the centerlines farther in, thus reducing the track. The "intuitive" track (overall footprint) is the same. --Andi

: : : Can anyone explain to me why the 323i's front/rear track is 58.3/58.6 while the 328i's front/rear track is 58.0/58.3. Why is there a .3" difference between the two.

: : : Thanks

: : : DAT


: Changing the wheel width won't change where their centerlines are, you need to change the offset to do that. Where are those track figures from? The bmw.ca website listes both cars with the same track (58.3"/58.6").
