The rear section of the GA-K platform was specifically designed to accommodate the multi-link suspension. A rigid high-torsion rear body frame is used to firmly support suspension input during acceleration, deceleration and cornering. High-rigidity foam optimally positioned around the back door opening provides effective reinforcement while enabling a lightweight and highly rigid body. In addition, the mounting points for the rear suspension and the rear suspension member have been significantly reinforced. Short pitch welding, LSW (Laser Screw Welding) and structural adhesives were used to further boost joint strength.
