an lsd provides its biggest benefit in straight line grip.. on a turn, it can hurt you a little bit.. here's the reason...
with an open differential, if you're making a turn and your inside tire loses grip, it starts spinning. the other rear wheel maintains its grip because its almost basically freewheeling, there is no force on it so it just rolls and you have 3 wheels that are in control.. so in that case you dont lose control..
with an LSD if one tire loses its grip, all the power you were putting to that tire, now goes to the one remaining gripping tire.. chances are that tires is now going to slip so you end up with only your front 2 tires having grip.. not too stable of an arrangement... at this point generally your rear slides out and you can A) lose control and end up facing backwards and hitting something or B) be aware of this and know how to counter such an occurrence....
