If you’ve ever found yourself in a car conversation with one of your nerdier car-person friends, they’ve probably mentioned how a certain performance car does or doesn’t have an “LSD.” No, they are not talking about hallucinogenic drugs.
In car-guy speak, LSD is short for limited-slip differential, and judging from the name, you might assume that limited-slip differentials, well, limit slip. And you’d be right. But how does it do this? What is an LSD exactly, and how does it actually affect the way a car drives?
