A lot of the car's behavior will be dictated by the overall package you're running. I did not run a rear bar for very long on the stock suspension, but with aftermarket coil-overs LTO is more pronounced, especially on off camber corners(obviously). With my setup (22mm bars front and back, coil-overs, ALK, Cusco strut braces ft/rr, hard mounts and hardened links, 18" wheels, 40 series tires) breakaway is fairly consistent and progressive. I've noticed that the car rotates much more aggressively when trailbraking, since the rear is unloaded a little more than if I were braking entirely in a straight line before turn in(again pretty obvious). Just beware of using too little throttle. When the car goes to oversteer lift slightly, but not completey and when it goes to understeer (on exit), keep your foot in it. That's the beauty of AWD.

You shouldn't experience snap oversteer unless you are over the limit and by that point, you're either trying to induce oversteer anyway or you're on your way to an expensive and sudden stop. You should be fine, unless you're going with a >24mm rear bar on the street. Definitely not recommended.
