at what point would you suggest sub fram connectors?

I have a 94 mark VIII
the engine that is going in the car makes 416hp at 5600 RPM and 410 ftlbs of torque.
this car will be used as a street rod but may go to the strip once in a blue moon to see what it will do
do you feel that this car needs sub frame connectors?
and if so who makes them?
thanks in advance

RE: at what point would you suggest sub fram connectors?

Johnny langton used to make subframe connectors, but i don't think he does anymore.

I don't think you'll "need" them, but they do stiffen it up a little.
