The GTO got a "brother" which was actually the predecessor: The Ferrari 250 Berlinetta GT "Passo Corta", or more commonly known as SWB - short wheel base.
The Ferrari 250 GT SWB was, similar like the GTO, a winner on any track. But unlike the GTO, it was built also to be a roadcar (I mean - the GTO was road legal, too; however it was premarily built for racing only) which could take you to work (or golf course) every day. In fact, not few SWB were winning a tropphy on Sunday and used to bring the offspring to school on Monday...
Between 1959 - 1962, 167 cars were made in slightly different versions.
