Porsche 550 RS Spyder

As their first dedicated sports racing car, the 550 RS Spyder was raced to Porsche's first major victory at the grueling 1956 Targa Florio.
With Dean's mystery, the multiple class victories and the recent relaunch of Porsche's mid-engine roadster (the 1998 Boxster), the 550-era was easily the most defining era for Porsche history.
