WARNING: This page is about a different car, the 2016 Porsche Macan and 2015 Porsche Macan. However, it is still accessible from the selected car via links, so may be relevant.
Body structural foam is ideal for increasing the rigidity, strength and fatigue endurance limit of cavities, plates and structural parts, e.g. pillars, door sills and frame sections.
