The classic double A-arm with a separate toe control link. Usually configured with unequal length non parallel A-arms, but can also be parallel A-arms, either equal or unequal length.

When used as a front suspension there are five chassis mounting points, two for each A-arm and one for the steering tie rod (which can be either the end of the steering rack, or the tie rod mounting on the track rod).

When used as a rear suspension there are either four or five mounting points, two for each A-arm, and either a separate toe link mounting, or the toe link mounting can be common with one of the A-arm link link mountings.

Three upright mounting points, one top A-arm, one bottom A-arm and either a steering arm or a toe control link mounting.
