Limited Slip Differential (LSD)
What is a limited-slip differential and what is it good for?
A limited slip differential (LSD) is a device on a car that limits the amount that a wheel spins, for example, when a car loses grip on the road. In this situation, the LSD redistributes the engine power to other wheels that have more grip, either through a mechanical system, an electronic system, or a combination of both.
LSDs tend to be found on sports cars and SUVs.
