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

MopaR&D said
For them to be "designed right" would make them expensive and enough of a pain to install (read: drilling lots of holes and installing lots of bolts) that it wouldn't be worth it vs welding them in.

Possibly, you guy's take pointing out a fact as the same as an endorsement, never said it was generally better or the way to go.
