To give the LC convertible with its soft-top roof the structural integrity at the heart of the LC’s dynamic performance, it integrates several exclusive components to boost body rigidity. They include a rear suspension tower brace with V-brace, torsion box, under floor braces, and gussets on the bottom of the front and center pillars. The use of aluminum, hot-stamp, and high-tensile steel further contributes to the lightweight, high rigidity body structure, reinforced by the use of body adhesives, laser welding and laser screw welding. To further lighten weight and lower the center of gravity, aluminum and CFRP (Carbon Fiber Reinforced Plastics) are used for a variety of components.
