After growing attendance and notoriety within the rotary community, SevenStock began to gain the attention of top tuners and even Mazda itself.
Mazda North America President Charlie Hughes was on-hand to introduce the 4-rotor 700 horsepower (520 kW) race car to the crowd.
SevenStock 5 hosted an estimated 4000 attendees and vehicles had to be turned away as over 400+ enthusiasts filled the Mazda parking lots and surrounding streets.
In addition to the return of Mazda North America President Charlie Hughes and program manager Koby Kobayakawa, Kazuo Takada was also on hand to reminisce for the crowd.
SevenStock IX signaled a change for the event, as it was moved to Mazda's corporate headquarters in Irvine, CA, just a few miles from the R&D site.
Today SevenStock has grown to become one of the largest all-rotary car shows and events of its kind and continues to be the Mecca of all things rotary.
