THE 323's suspension system utilises a MacPherson strut arrangement at the front and MacPherson struts with twin-trapezoidal links at the rear. The lightness and rigidity of the front suspension is maximised by 68mm diameter pipe for the front cross-members, single lower arm structure made possible by the use of high-tensile steel and vertically aligned bushings on lower arms.

The rear suspension has been seen in previous 323 generations.
