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. |

This is what I would do Randal:
Get rid of the top of the sheet metal behind the engine compartment and install a tube going all the way across, just ahead of the shock towers. You can terminate the main hoop braces onto the cross tube or land them on reinforcing pads at the ends like in my pic. My design improves engine compartment access, and you can add small triangulations between the rear braces and the crossbar if you want. Then attach the tranny crossmember braces to the shock tower crossbar next to the shock towers. Don't put the rear attachments together to form a triangle. It is better to keep them apart and land them just above the tranny mounts. Attached image(s) |

I can't draw a picture with the tube in front of the shock towers, but you get what I mean. Like this? I'd still like to see a picture of what the cross pipe looks like at the ends. Thanks again Chris. |
