Subframe connectors for a driver/cruiser, necessary to weld to floor?

I went with the Mancini/non-floor welded connectors after a similar discussion a couple years back, no regrets.

The thing that seems to be missing here is the debate over torque boxes. I have no data to back this up but the Torque boxes may actually be more important since this is what Mopar chose for factory high performance equipped cars.

As has already been pointed out, the factory isn’t the last word and they were working with much lower traction levels due to tires of the day…but it’s hard to imagine that the torque boxes would have been cheaper than the subframe connectors in terms of manufacturing.
