I highly rate my quaife LSD, it has changed the way I drive it, where before I would understeer with anything but the smallest throttle input in a corner it now pulls you around the bend, you effectively steer with the throttle now and it's complimented by the rest of the car's setup at the minute, it's very neutral but when it does break traction it does so progressively and it's very controllable on the edge of traction.
