DESCRIPTION OF R EA R AXLE
The rear wheel suspension incorporates radius arms _ the geometry of which provides favorable camber and the best possible tracking characteristics.
Wheel springing is by suspension struts. These are combined assemblies consisting of coil springs, double action shock absorbers ,
The pivoting of the suspension strut assembly at the radius arm and at the anchor point on the body causes constantly changing ratio between spring compression and wheel movement. This provides progressive increase in suspension stiffness on the wheel stroke bump
Power is transferred to the rear wheels by two drive shafts , each with two CV joints.

Table Caption: This table compares the general specifications and rear wheel suspension details for two vehicle variants: a 1.7 liter 76 HP model and a 2.0 liter 91 HP model. While many specifications like wheelbase and permissible rear axle load are identical, the 2.0 liter model lists specific details for its rear coil springs and has a different standard tire size and rim size.
