Cross members and bracing are indeed components specifically designed to enhance the stiffness of a unibody structure. In automotive design, the unibody structure is critical for overall vehicle integrity, safety, and performance. Cross members are structural components that run across the width of the vehicle and connect different sections of the frame, helping to distribute loads and forces evenly. Bracing adds additional support and rigidity to areas that experience dynamic forces, such as during collisions or while driving over uneven surfaces.

While other components, such as subframes and reinforcements, also contribute to the overall structural strength of a vehicle, cross members and bracing are particularly important for providing stiffness against torsional and bending forces. Shock absorbers and struts are essential for suspension performance but do not perform structural functions in the same way. Body panels and welds contribute to the overall strength and rigidity of the vehicle but may not specifically stiffen the unibody structure as cross members and bracing do.
