LIKE the Holden Astra upon which it is based, the Zafira chassis incorporates a refinement-enhancing hydroformed subframe, which is attached to the underbody by six damping bushings, as well as a MacPherson strut front suspension and a torsion beam rear suspension configuration. Front and rear dampers were recalibrated to suit Australian conditions and Holden engineers increased the durability of key components such as rear shock absorbers. Together with the wide track and space-saving minibloc springs with separate shock absorbers, the torsion beam rear axle makes a big contribution to interior space saving.
