The limited-slip differential uses clutches, gears, or viscous fluids to transfer torque away from a slipping wheel and send it to the wheel with more grip. Unlike an open differential, it prevents one wheel from spinning wildly on ice or during hard acceleration. It provides a balance between smooth cornering and high-performance traction.
Upgrading to a clutch-type LSD completely transformed how the car puts power down out of the corners.
