It's all balance. Stiffening up the front will make the vehicle feel like it's working more cohesively, just like adding more sway bar to the rear of a car can have the same effect as lessening sway bar in the front, it'll reduce understeer. The back and the front need to work together. The issue comes down to comprising stability or flex, like the difference between a double triangulated suspension and a single, racers use single for stability, crawlers like double for the flex, or less stability with a 3 link but epic flex. To really balance it, you'd want match the front and back, ie link the back or leaf the front, but that opens a whole can of worms I don't think you want to get into.but it's that balance that makes a lot of guys run a rear sway bar on a rig with a linked rear
