The rear size will rub on the front fender liner under certain conditions
A nineteen is big enough to fit the BMW jack kit inside and an eighteen isn't fyi

can you please clarify your last statement? Sorry, i am kind of a newbie here. What do you mean by "eighteen isn't fyi?" And when you say, the "BMW jack kit inside", do you mean that the m3 comes with a jack kit?? I was assuming it does not since it doesnt come with a spare, but I may be wrong!!!
Will the rear rub the front fender liner under normal highway driving conditions?? This is one of the reasons why I have ordered mine with standard 18"ers without the lowered suspension. I do need the practicality of the 18"s in my neck of the woods........
And I completely agree with you on the differential issue. Those were my exact thoughts, 'cause sometimes the routes that I ply on between Texas and Oklahoma, it can happen that you have to drive a good 80-150 miles, sometimes even 200, before you can get to a good wheel/tire store or a BMW dealership. And roadside assistance, as good as it maybe has its own limitations. I would rather have the capability to get home and then go to my regular dealer. sometimes I dont have an option given the time and work schedule.
but many thanks for your input, confirms my thoughts, rather save the differential and deal with a lill pull on the highway than mess around with uneven circumferences at the business end of things......
