1986 Mustang Torque Box Reinforcement

[my89notchback]

I don't know at what HP levels either but from the sounds of it I think your all set. I have just the stock boxes all welded up along with the rollbar supports and I'm in the single digits in the 1/4 without issues

Overkill with torque boxes doesn't exist in my mind. I'd weld them all the way around while your in there, they make some bottom plates you can weld on that tie them into the sub frame alil better plus battle boxes. I'd fully weld it all, the plates the boxes and the battle boxes. I even welded the bolts to the plates and the nuts after i tightened in my old car then added upper bars as well just for the fuck of it. Then you don't have to worry about them ever.

Thanks for the info guys. That is exactly what I wanted to know. I appreciate it!!
