The front of the S660 has a monocoque structure with no subframe, but since the strength of the genuet gazette plate of the lower arm attachment part is not sufficient as on the image, twisting will occur especially during hard braking or roll. Found there, a rigid body plate integrating the left and right lower arms and the body of the front.By making the suspension and the body one BOX like a subframe, it made direct and stable maneuverability possible. First of all, CAE analysis of the body is carried out, designing by SPOON original design and development method, based on it, designing a special press mold by 3 dimensional CAD, cutting by the machining center.Material is usually 2 mm thick JSC 780 ultra high tensile material which is only adopted for the framework part of the chassis, it was molded by 800 t hydraulic press. Specification similar to genuine finish. Remarks & special note ust by replacing and replacing the genuine plate and bar, the genuine under panel can be installed as it is without processing etc.
