Other than better traction in turns, im wondering what the offset of having too much..or I guess to little limited slip action.
Increasing the stiffness of the rear diff makes the car apply power better to the ground in a corner and also even in a straight line. A stiffer rear diff makes the car corner better under power but lose some off power turnin.
The 4 gear conversion for the rear diff increases the total surface area of diff gears moving against other diff gears which increases mechanical friction making the diff stiffer. Also since there is more surface area of planetary gears the effect of a given weight of silicone lube is greater than if you only had 2 planetary gears.
