HYP04A Occasional Poster Registered: March 2004	Re: whats a LSD? Mon, 08 March 2004 22:24 Limited Slip Diff. What this thing does is create a link between the rear wheels (or front wheels, in a FWD car, and often between the front and rear wheels as well in a 4WD) so that instead of letting them spin freely with respect to each other, they have a certain amount of friction. I'll be talking about three types, but only two in any detail. The cheapest and certainly the nastiest to drive is what we call in Australia as the 'CIG Locker'. What this means is that the centre of the diff has been welded up (By using an oxy welder, almost invariably powered by CIG gasses, gettit??) so that the rear wheels are solidly locked together. This makes the car very hard to turn around slow speed corners, as the inside tyre wants to rotate at the same speed as the more heavily loaded outside, and so tends to push the car in a straight line - big time understeer! If you have enough power, then you can get both rears spinning nicely, and so create and control the oversteer that will then develop. You really have to drive the car on the throttle a lot more than a 'normal' car, and so they can be a quite tricky unless you get used to it quickly. What's far more common - and pleasant to drive - is the Salisbury (pro: Sawls-bree) LSD. All they are is a conventional open diff, but with a clutch pack on the axle diff gears so that there is friction created between the rear wheels when they rotate at different speeds. There are a couple of different ways of getting the LSD to work - There are the options (from Toyota, at least) of a '1 way, 1.5 way, or 2 way'. What this means is that with a '1 way', you only get the LSD action when under power. A '1.5 way' has a little LSD action when on trailing throttle. (good for controlling the car when cornering) And finally the '2 way', which is the sideways driver's dream, as the car will want to slide everywhere. Possibly the best LSD of all is the Torsen 'torque sensing' type. They are a very good thing, as they always spread the torque evenly between both wheels at all times, so even if you have one tyre on ice and the other on sandpaper, both wheels will spin evenly. There are two types of Torsen [Report message to a moderator]
