Do wagons need sub frame connectors

Ok, so most here know I am crazy about wagons and I am currently working very active on my wagon.

my thought of the day is: Do wagons need subframe connectors??

It has become my standard practice to install subframe connectors on my 2 door cars even for street use and it makes a huge difference, but that is on a 2 door car with the front seat mounted right over the weakest part of the floor.

Now I am looking at my wagon and its a 4 door so it has this massive B-pillar for support and this thing looks like its built like a tank.


So it makes me wonder if it would really benefit and stiffen up any more than it already is with subframe connectors ???
