Restore your Porsche’s strength, structure, and originality with genuine Porsche and reproduction floor pans & floor pan sections from Design911. These essential body panels form the foundation of your Porsche’s chassis, providing rigidity, safety, and support for the seats, interior, and underbody.
Over time, floor pans can suffer from rust, corrosion, or damage, especially on classic and air-cooled models. Our range of OEM and reproduction floor panels are manufactured to factory specifications, ensuring precise fitment, accurate contours, and structural integrity — whether you’re performing a full chassis restoration or repairing a localised section.
Made from high-grade steel or aluminium, these panels deliver long-term durability, perfect weld alignment, and corrosion resistance. Design911’s comprehensive selection covers full-length floor pans, half panels, and repair sections for both classic and modern Porsche models, supporting restorations from the 356 to the 992.
