just to correct a few misunderstandings on a Limited Slip diff. it is not only useful to just high power cars. if you think the non-Ms devour the corners now, or have impeccable road handling...with a LSD it handles much better. people often confuse a LSD for just putting down power in launches or drifting, they actually do a great deal for handling.
