Basically in real world driving, a thicker rear sway bar gives much improved grip for turn in, but as a result the rear can come unstuck easier if you lift of mid corner. Don't let that scare you though coz it's easier to recover also as everyting responds faster to your inputs.

I was saying that if you increase rear stiffness you decrese front lateral weight transfer and vice-versa. Rear end independance means nothing on a front-wheel drive as you are ultimately cornering on 3-wheels. Just like a rear wheel drive lifts the inner front, you want to unload the inner rear completely. You want to be careful not to over-load the inner front however and heat it up to a point of non-grip. It's far from an exact science, hence why motorsport costs a lot in testing etc...
NB: You obviously don't want to be lifting the inside rear off the ground when driving around the street, but the same phsyics still apply, just to a lesser degree.
