1958 – 1959 Porsche 356A/1600 Super GT Speedster – Ultimate Guide
A handful of push-rod 356As were delivered from the factory with a lightweight package that was usually reserved for the Carrera race cars. Called GTs, these got the stripped out interior, aluminum doors, a large fuel tank and Porsche ATE disc brakes.
As few as four Speedsters came equipped this way. Since the four-cam was only a marginal improvement in power, the regular 1600 Super was more than enough for the small car. It was also easier to maintain and overhaul the engine since they were manufactured in very large numbers for the general public.
