General body structure
This car has a unified body, which includes built-in front and rear longitudinal frame spars.
The lower control arms of the front suspension are bolted and held by supports (calipers), one on the left and one on the right. The front suspension lower control arm calipers are attached to the underbody with three bolts in two places. The engine is bolted to the front longitudinal spar. The suspension struts must be properly sized in relation to the rest of the underbody to maintain the proper suspension strut and front cast/camber angles.
Since the individual parts of the lower bodywork play a direct role in the strength of the vehicle as a whole, it is important to follow proper welding techniques during repairs. Underbody parts must be properly sealed and protected from rust whenever the original seal and rust protection is compromised during body repairs. When protecting critical underbody parts from rust, use an air-drying primer such as anti-corrosion chromate or similar. It is not recommended to use a primer / putty combined type.
Engine mudguards
The engine mudguards are molded plastic parts that act as protective shields for the underside of the engine. Shields help protect the engine from small stones, gravel, and other objects that would otherwise fall on the engine under normal operating conditions.
