I've heard a couple IS300 owners on this board that have chirped their tires for a sec or so upon take off. LSD should make it more difficult to do so. I think the final drive ratio probably has something to do with this, because when I had my GS400 (equipped with LSD) if I floored it from a stand still, the car will give a little chirp and shoot off... I heard that low tire pressure helps you spin your tires off the line..
