the diff works on torque differences on these cars. it has to do with angular momentum and the dynamics of rotational bodies.

A
differential is a device, usually but not necessarily employing gears, capable of transmitting torque and rotation through three shafts, almost always used in one of two ways. In one way, it receives one input and provides two outputs; this is found in most automobiles. In the other way, it combines two inputs to create an output that is the sum, difference, or average, of the inputs.
In an
automobile and other wheeled vehicles, the differential allows each of the driving
wheels to rotate at different speeds, while supplying equal
torque to each of them. In automotive applications, the differential and its housing are sometimes collectively called a "pumpkin" (because the housing resembles a
pumpkin).
vehicle's wheels rotate at different speeds, especially when turning corners. The differential is designed to drive a pair of wheels with equal force, while allowing them to rotate at different speeds. In vehicles without a differential, such as
karts, both driving wheels are forced to rotate at the same speed, usually on a common
axle driven by a simple chain-drive mechanism. When cornering, the inner wheel travels a shorter distance than the outer wheel, resulting in the inner wheel spinning and/or the outer wheel dragging. This results in difficult and unpredictable handling, damage to tires and roads, and strain on (or possible failure of) the entire drive train.
diffs have been around since the train days in mechanical vehicles. just like leaf springs
lsds are for better traction
basically its the slip in the tire that causes the massive torque which must select lsd clutch plates etc ordered placed correctly in the lsd.
