This is not quite correct. A larger front swaybar increases the load
on the outside front and inside rear tires, and decreases the tires
on the opposite diagonal. Whether this is a good thing depends on a
bunch of other factors. With a front engine way up in the air you
usually already have too much weight on the outside front tire, so
the result is to reduce front traction. Similar arguments apply at
the rear, where the center of mass is much lower. The roll center is
also different front to rear, usually much higher at the rear,
especially with a swing axle. The result is that you start with even
more weight already transferred to the OF/IR diagonal. Yes, having
the car sit flatter in a corner is good, but the weight shift onto
the already overburdened diagonal makes understeer worse.
