Yours looks different than mine. Besides mine having two door bars (that bend outward), my main hoop connects back to the rear wheel wells.
I'm using mine temporarily (got a helluva deal on it) for HPDE and while I get my license, then I'll go to a full built cage for competition.
So while we're on the topic of these cages, anybody have the same model as mine? I'm having a hard time getting the top passenger side door bar to go in. It's like the two connecting ends (on the main hoop and the bar going down the a-pillar) are not lining up. The cage was (allegedly) never in an accident, and it doesn't look like it took any damage. Not sure if it's tweaked and I can't see it, or if I'm just being an idiot.
