Like Ernie, I also opted for one full width bar. The RMC kit I have has substancial deep sockets welded to the chassis on both sides and the thick walled roll bar should take one hell of a impact before crumbling.
Ernie mentioned Marks accident. Having seen the pics of the car against the post, with the apparent lack of body/chassis damage. Together with the injuries as described by his Sister. It raises the question whether Mark's injuries were maybe caused by his head impacting the post.
Speculation I know, and a roll bar wouldnt have helped in any case.
In any event, My first wife wanted her head protected as much as mine so the full width bar it is.
