what is wms to wms on a axle
Axle Width (WMS to WMS) - this is the distance from where the wheel sits flat against the hub/rotor assembly on one side to the same surface on the other side of an axle. If you are using wheel spacers or any kind, they should be included in this total width as well (for example: 60 WMS to WMS with 1 spacers on each side = 62 WMS to WMS). Wheel Backspacing - this is the distance measured from the inside (or back side) of the wheel edge towards the center of the wheel where the wheel contacts the hub/rotor assembly when mounted on the vehicle.
