Nick and all A missing stiffening cross member could be a relevant issue. Is this item really in such an important function or is it just there to make the job as a sparewheel holder?
Is someone aware if the Roadster Sport is also missing this item? And as a reference representing the state of the art, I´m wondering if the +4SS comes with or without this cross member.
IF, and only if it should be relevant I would immediately sacrifice the won space in the back of the Roadster Sport and would instead let install such a cross member to prevent any future faults ref the wind screen or too much body wear in general. I guess it should be possible to install this stiffening cross member afterwards?
