What is the minimum amount of bar that would need to be added from the back towers to the transmission cross member? Understanding that I am running a bar from the back hoop of the cage to the shock tower.
Could I just run a bar from a plate on the rear side of the shock, midway to the top of the transmission cross member? Just a simple triangle. Would that help? Picture below. |

I usually use 1 1/4" x .083. 1" x .065 is the lightest I would consider using. Reinfocement will definitely make a difference once the floor has been cut out around it.
Mark, IMO your test method leaves a lot of room for error. The weight of an engine/trans assembly is at least 200 lb on that crossbar and the forces applied in operation are certainly greater than someone jumping up and down on it. |
