A further challenge in the body development of the new 911 GT3 Cup (991)
consisted in connecting the floor assembly largely made up of aluminum parts to the
steel assemblies of the body. Bonded joints are used in addition to pierce-riveted,
clinch and flow drill connections. The benefit of bonded joints is the force
transmission over the entire surface, increasing the strength of the joint.
Further developments in steel processing allow using ultra-high strength and
extremely thin-walled steels that are tailored to the individual field of application of the
body. They provide very high stiffness values and safety while reducing material
usage to the maximum.
