L.S.D, When, wut, why? Options

[Lil-Joe101]

Ok, so I see everybody talking and L.S.D.(Limited Slip Differential for those who are behind the curve) When would I need one and wut is the point of haveing one on a FWD car? I saw that TRD makes one for the 3sfe but I wanna know wut is the point of haveing one?

Can anyone answer this question for me?

Thanx

wtf is LSD?

A standard (open) differential is a set of gears, typically between the two drive wheels, which allows the wheels to turn at different speeds. This is important for cornering. However, a standard differential can lead to loss of traction under extre

When there is a difference in traction between the left and right wheels, on a car without LSD (a car with open diff), the wheel with the most traction will move less and the wheel with less traction will rotate more (scenario A). Taking this to an extreme, if one wheel is in mud or on ice, that is the wheel that will rotate and the one with excellent traction will stay put (scenario B). It should be clear that both scenario A and scenario B are the opposite of what you want.

An LSD is a clever set of gears, a little like a clutch, which allows for small differences in rotation speed between left and right (such as is needed when cornering) yet continues to drive both wheels even when there is a large traction difference between left and right.

The wikipedia article, while technically acurate, isn't a particularly good introduction to the subject. Try these instead:
