It isn't just width, it is offset. Every rego time for my old Datto 1600 I would have to put on stock rims, because the old kidney style rims that were probably on since the car was only a few years old added 1" to the track (wheel centre to wheel centre) which is not legal as they claim it puts undue stress on bearings and screws steering geometry.
The silly thing is if the rims were 0.5" wider (towards the middle of the car) the track would have passed.
