It could be the same as with FWD cars the rear wheels are the one you want to go up in size or add a sway bar to to get the car to rotate into the corner and not push .. Right ? So with the stiffer rear beam and different springs maybe the front was ok as it was .. Or I could be all wet here maybe BRGT350 can shed some light as he has both cars ..

Stiffening up the rear on a fwd car helps reduce understeer.

Isn't push and under steering the same thing?

I will let Richard Hammond explain
