I suppose I could but your question did only call for a yes/no answer....
really simply- LSD's help you put more of the power you have down to the ground
they won't give you more power, just help you use it more effectively
do some research on LSD's and you will understand why you want one, what engine are you thinking of buying?
what are you going to be using your car for?
3 basic types....
viscous [pretty much worthless if it is old, but decent for a daily driver car]
clutch [best for drag racing... this is a true LSD]
helical [better for auto-x or road racing, not really a LSD, actually a "torque biasing differential]
spend an hour or so on google, or just go over to the quaife website and read up
