Well, that is what i was afraid of. I was thinking that all E46 parts would be interchangable, you would think that they are. but i guess you cant argue with measurements. I am wondering about the M3 wheels. i dont really know what it means to have a different offset. So if someone could explain on how a wheel with the same 5 bolt style, that the measurements fit, how could it not work? or does offset have something to do with the 5 bolts or something or other.
