The classic production car Macperson strut.
When used as a front suspension there are four chassis mounting points, one for the strut rod top mounting, two for the lower 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 three or four mounting points, one for the strut rod top mounting, two for the lower A-arm, and either a separate toe link mounting, or the toe link mounting can be common with one of the A-arm link mountings.
Three strut mounting points, one for the strut rod top mounting, one bottom A-arm and either a steering arm or a toe control link mounting.
The design of the wishbone can take several forms.
Two of the most common styles are
| • | a single lateral control arm with a trailing link (where the anti-roll bar is used as the trailing link in which case this is the classis "Macpherson strut") |
| • | a one-piece 'sickle' or 'L' shaped arm |
The king-pin inclination and caster are measured from the strut rod mounting point on the chassis and the bottom wishbone strut ball joint.
