it allow power transfer between the rear wheels
so power goes to the one wheels needs it
to compensate for spin, or loss of traction
ideal for drag racing, so u avoid a peg-leg burnout (one wheel burnout)
so u wont lay eggs on the line

not ideal for drifting, cuz it will balance the car out , reducing angle and cutting your drift short

pple weld thier diff for drifting so both wheels spins its easier to control the drift this way
but welding the diff is not advisable for street driven cars
unless u dont mind a wheel hop everytime u try to park ur car into a parking space

but im still doing my reasearch on em, i might b wrong in sum points
but this is the best of my knowledge
if im wrong, i already stand/sit corrected

but i belive thats diffent types of diff. for diffent applications
