um where are the front tubes supposed to be going
you have too much pipe in there
why would you build a cage from chromoly anymore, totally pointless, wall thickness must be consistent regardless of material which invalidates any benefit from chromoly. read the rule book. or read about roll cages. what am i talking about this is zilvia.
anyway using a strut bar as a harness bar is retarded and unsafe. you want your harness bar to be as close as possible to yourself. you want minimal excess webbing so you have less stretch. and you want it up by your shoulders. not like down by your lower back.
Xing the roof halo is stupid, so much weight up high (worst place) for no reason.
also the rear part (im assuming you got that from some kind of drag racer cage picture where they have to tie into the rear frame rails for the rules/helps with launching) is stupid.
if you went into a chassis shop with any of those pictures they would just say youre retarded and build you a cage that looks like everyone elses cage. dont reinvent the wheel.
make that
the sooner you realise the reason you want all that shit is for cool points and nothing else, the better off youll be
