Dual pivot steering geometry

Dual-pivot steering geometry (also known as virtual pivot) is a geometric arrangement of linkages in the steering of a car designed to reduce or eliminate scrub radius by moving the pivot point of the king pin outboard, in order to improve steering precision and straight line stability.[1][2]

It is typically used with a MacPherson strut, but can also be applied to a double wishbone suspension.[3] In either case, the difference is that the single bottom wishbone is replaced by a pair of suspension links forming a trapezoidal four-bar linkage. This allows the kingpin to pivot about a pivot point nearer the center of the wheel's contact patch instead of the traditional pivot point at the ball joint of the bottom wishbone.[2]
