I had considered this approach as well. Unfortunately, roll bars are
only allowed under Apendix C which is somewhat dated in it's
construction requirements. The GCR does a good job of requiring minimum
tube diameter and wall thickness based on the actual properties of the
material. Appendix C just requires THICK wall tubes.
If all I had to do to meet Appendix C is to use a thick wall main hoop
and rear supports I suppose it wouldn't be too bad. However, it's not
clear if I can hang a bunch of 'stuff' off it in the form of side hoops
and not be subjected to the contruction requirements of Appendix C.
BTW, one of the reasons I wish to not build a full GCR cage is my desire
to use somewhat unconventional door bars much like seen here.
