I have seen wheelbase checked 2 different ways in teardown. The last time I watched, the tech guys had a piece of aluminum about 15 inches long by 3 inches wide that had a mark in the center, held it against the wheel and measured by tape measure to the front spindle. Another time they put the edge of the tape measure on the front or back of the rear wheel and measured to the corresponding spot on the front wheel. They also made sure the wheels were straight before starting. I have also seen the tech guys measure the front and rear overhang(to the end of the car) but I have never seen a spec on this.
