you need to add a virtical rizer in the middle (see thick green lines ) and move the red bar with the x on it to where the orange line is and it is always good to add some door bars othe than that it looks like it will be a very strong cage and don't forget to add gussets
are you planning to add five point harnesses if so you need to add some horizontal bars across slightly below shoulder height
I asked him & he said he wants to be able to open the back doors or Id agree he needs support where you put the green lines, so to take care of the strength issue there, I will be running an interior X out through the roof and tieing it into the halo right behind the front seats, also keep in mind just behind the back doors where the roof will end and the halo drops down there will be another large X/tie mount and a cross brace, also the roof where the rack use to be will also be */x thats an X plus an additional bar, one thing for sure, this will be one rugged -bash into off of & over anything he wants to hit!!!
As soon as I get started on this EXO I will be sure to snap a few pix and post them up!!!
Last week I just removed my EXO off of my buggy to redo it, so as soon as thats done/underway I will start on Nates rig!!!
Stay tuned!!! Scott <CentralMassSamurai>
P.S my harnesses out of my drag car expired this summer so they wont pass tech next season,,so maybe Ill supprise Nate and put them in for him, something tells me he might need them
