Tailored blank usage Tailored blank: rear rail outer (thickness in mm) Careful placement of the seams in the tailored blank was critical for minimizing weight and facilitating forming. This consideration was especially important in the body side outer because of its complexity, its size, its use of high strength steels and the inclusion of a class A surface quarter panel.
