I am not sure if you are referring to Negative Diff that made by Kawahara or Kyosho.
Anyway, Negative diff VS standart gear diff:
Standard Gear Diff only have gears inside the diff obviously! and you will need to fill it with different weight of diff oil to make the gear diff loose or tight depending on what weight of oil you put in there!
Negative Diff, actually it has 2 different housing and sealed from each other and they are side by side. The only thing that go between both housing is the left outter drive. The housing on the right has regular gears that you put into regular gear diff and you will also need to fill it with diff oil,(different weight of oil will result loose diff or tight diff) and on the left side of the gear diff housing which is another housing that has 2 fingers clutch in there.
The concept is when the whole rear diff that pulls by the belt spins fast enough then the clutch will engage by concentric force then it will become a solid axle but when you slow down the concentric force is not enough to spin the finger type clutch fast enough so it will disengage then you will have diff action.
So the best effect or result from a Negative Diff is to use light weight of diff oil or diff lube to allow really smooth diff action for tight corners and when you punch out of the corners then it becomes solid axle and the car will rocket out the corners also the car will be much stable on highspeed straight away!
Hope that will help!
