Wheelbase measuring tool VW Audi Skoda Seat (5x100 or 5x112)

The centering hole is normally 57.1 mm in diameter but I've added a bit of clearance (actually 57.5 mm) to be able to install the part on the car if necessary (unlikely since you just have to put the part on the rim to see if the center distance matches or not) The center hole is marked 57.1 mm but is actually 57.5 mm in order to put it on the car with a small play. Just put it on the rim to see if the holes are matching or not.
