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. |

Randal, have you noticed any issues with the trans mount bar flexing? I had a 200 lb guy stand on it and then jump on it and didn't see any flex. I would think that some pretty lightweight bars would be all that would be needed for a little 'added insurance'. The area is pretty strong as you have it, IMHO.
Assuming a magically rigid chassis from the rear shock towers forward, I can't see how the rear frame (shock towers to trans mount) would flex. If your shock towers flex, they'll take the trans mount bar along for the ride. But once your cage locks those rear towers into place, the transmission is going to have a hard time going anywhere. Again, I would think some really small bars would be all you would need, or nothing at all. |
