There are other ways to fix understeer, is what it comes down to. Primary purpose of the sway bar is to reduce body roll, however a side effect of a antisway bar is that it causes some load to be transferred to the outside tire-which ends up causing "push". Push in the front is understeer, push in the rear is oversteer.

Body roll itself does not cause that much understeer mathematically. But it is scary as hell and destabilizes everything when you are going through the esses for example. So the more correct way of looking at it is that a anti sway bar is there to prevent body roll, however when you use one, it is going to affect the way the car handles in terms of under/oversteer. If you did have "too much front bar" yes the front would "push" around the corner.

However I think a better way to solve it would be stiffer front springs, damper settings, and tuning the rear sway correctly which are all valid ways to get the car to rotate. All of those would be better than "not enough front bar to reduce body roll to an acceptable level".


That's my interpretation of it anyway.
