^^^Yeah, upon closer inspection of the interior pics from that last sales posting listing thread for one of these, and this post, I realized that it is
barely a 'single impact/easy rollover' protection provider.
(I've never seen a pic of their 'cages' up close/in person before this, not having had the privilege of attending the Utah OA myself when my car was new.
)
NO; triangulation, gusseting, reinforcement, or any of the other required items for most sanctioning bodies' GC rules.
The ARA (not to even mention the FIA WRC) spec cages might even be more intensive than those B-Spec ones, given that they have the chance to be hitting stationary objects at speed (dead stopping from trees and big boulders), and an even better chance of rollovers from hooking ditches, and flying off of the forest roads from ill taken 'yumps'.
