Once every year, on July 7th, tuners and enthusiasts from around the country celebrate Mazda’s shining triumph of engineering.  The RX-7, to many, is so much more than a car; it’s an engineering marvel. The unique rotary motor a triangular pariah in a sea of ordinary, piston driven combustion.  The chassis of the FD so perfectly geared towards time attack, has become a symbol of the sport in Japan.  On this date, thousands will come together in honor of this car worldwide, with the epicenter being Tsukuba Circuit.
